Electric knife sharpeners vary most in the edge angles they support, how much control they give you, and whether they handle tools beyond kitchen knives. My best overall pick is the Chef’sChoice 15XV EdgeSelect, which combines a three-stage process with support for converting knives to a 15-degree edge. The Work Sharp E2 is a simpler choice for routine kitchen upkeep, while the Work Sharp MK2 suits buyers who want adjustable speed and broader sharpening uses. The tradeoff is between guided convenience and flexibility: dedicated kitchen models are easier to operate, while more versatile sharpeners can take more care. Read on for the full breakdown and a guide to choosing the right sharpener for your knives.

Key Takeaways
- Chef’sChoice 15XV EdgeSelect leads for buyers who want a guided three-stage process and a 15-degree edge option; it offers more edge-angle flexibility than basic two-stage models.
- Work Sharp E2 is the straightforward kitchen-focused pick, while the Work Sharp MK2 adds adjustable speed and a wider range of sharpening tasks at the cost of a less specialized setup.
- The two Presto EverSharp models make a practical value-oriented pair, but buyers should compare their stage design and intended use rather than assume the word “Professional” means they suit every blade.
- Models with multiple stages, such as the Narcissus S809 and Chef’sChoice three-stage options, provide more steps for edge shaping and finishing; they also ask buyers to follow the sequence more carefully.
- Scissors and tool compatibility set apart models like the Narcissus QN-M866 and Work Sharp MK2, but a multipurpose sharpener only makes sense if those extra uses justify a broader, less kitchen-specific format.

More Details on Our Top Picks
Work Sharp E2 Electric Kitchen Knife Sharpener
The E2 is a good fit for home cooks who want a guided, push-button routine instead of managing blade angle by hand. Its built-in ceramic hone wheel also gives it a maintenance role between sharpening sessions, a convenience the Presto 08800 EverSharp’s two-stage sharpening and polishing setup does not specifically provide. The E2 covers kitchen and serrated knives, scissors, and shears, so one appliance can serve more of a household’s cutting tools. That range makes it more versatile than the Presto for mixed blade drawers. The tradeoff is that the supplied details do not specify multiple sharpening stages or an adjustable angle, so buyers seeking more control over the sharpening process may prefer the Work Sharp MK2’s two-speed belt system. It requires an outlet, and the guided approach may feel limiting to people who prefer manual control.
Pros:- Push-button guided sharpening helps maintain an even angle
- Built-in ceramic wheel supports routine edge maintenance
- Handles kitchen and serrated knives, scissors, and shears
- Includes a 3-year warranty
Cons:- Requires an electrical outlet
- No adjustable speed or sharpening-stage options are listed
Best for: Home cooks who want push-button sharpening and a separate ceramic wheel for routine maintenance across kitchen knives, serrated knives, scissors, and shears
Not ideal for: Sharpening enthusiasts who want adjustable speed or a more hands-on choice of sharpening technique
- Type:Electric knife sharpener
- Sharpening method:Push-button guided sharpening
- Honing:Built-in ceramic hone wheel
- Compatible tools:Kitchen knives, serrated knives, scissors, and shears
- Warranty:3 years
- Designed and calibrated:Ashland, Oregon
Our verdict“Choose the E2 if you want guided kitchen sharpening plus a built-in hone for several types of household blades.”
Presto 08800 EverSharp Electric Knife Sharpener
The Presto 08800 keeps its job focused: its two-stage system sharpens and polishes most non-serrated kitchen and sport knives, with blade guides to help hold a consistent angle. That simplicity suits buyers who mainly want to restore everyday straight blades at home. Compared with the Work Sharp E2, it lacks the stated ability to handle serrated knives, scissors, and shears, as well as a separate ceramic maintenance wheel. It also offers fewer stages than the three-stage 15° sharpener in this batch, which adds a polishing step and specifies a fixed angle. In exchange, the Presto’s straightforward setup may be easier to match to a basic knife drawer. Its key limitation is compatibility: buyers with serrated blades or a need for broader tool sharpening should look elsewhere. This version is built for 120 V North American power.
Pros:- Two stages sharpen and polish blades
- Precision guides help maintain a consistent sharpening angle
- Works with most non-serrated kitchen and sport knives
- Sapphirite wheels provide the sharpening material
Cons:- Not designed for serrated blades
- 120 V model is specified for North American electrical standards
Best for: Households with mostly non-serrated kitchen or sport knives that want a guided two-stage sharpening and polishing routine
Not ideal for: Buyers who need to sharpen serrated knives, scissors, or tools, or who need a voltage range beyond 120 V
- Model:08800 EverSharp
- Type:Electric knife sharpener
- Sharpening stages:2
- Compatible blades:Most non-serrated blades
- Sharpening material:Sapphirite wheels
- Voltage:120 V
- Electrical standards:North American
Our verdict“Pick the Presto 08800 for a basic guided sharpening routine if your knives are mostly straight-edged and non-serrated.”
Narcissus S867 Electric Knife Sharpener with Diamond Abrasives
The S867 stands out for blade compatibility: its coarse and fine diamond-abrasive slots are specified for straight, serrated, and ceramic knives, and it also includes a scissors sharpening feature. That makes it a broader match for varied household tools than the Presto 08800 EverSharp, which is limited to most non-serrated blades. Its 100–240 V input also gives it a wider stated voltage range than the Presto’s North American 120 V specification. The cost of that range is a more hands-on process: you pull each blade through the slots, rather than using the Work Sharp E2’s push-button guided sharpening. Anti-slip feet and a metal dust collection box support steadier, tidier use, though buyers need to follow the manual’s instructions before starting. Choose it for flexibility across blade types; skip it if you want the simplest push-button routine.
Pros:- Coarse and fine diamond slots sharpen and polish
- Compatible with straight, serrated, and ceramic knives
- Includes a scissors sharpening feature
- Anti-slip feet and a metal dust collection box support steadier, cleaner use
Cons:- Requires manually pulling each blade through a slot
- Instructions recommend reading the manual before first use
Best for: Cookware owners with a mix of straight, serrated, or ceramic knives who also want a scissors sharpening feature
Not ideal for: Beginners who want push-button guided sharpening or do not want to manually pull blades through slots
- Model:S867-2
- Power:30 watts
- Input voltage:100–240 V
- Abrasive material:Diamond
- Sharpening slots:Coarse and fine
- Compatible blades:Straight, serrated, and ceramic knives
- Additional use:Scissors sharpening
- Warranty support:12-month replacement or refund policy; 24-month after-sales service
Our verdict“Choose the S867 when broad blade compatibility matters more than a push-button sharpening routine.”
Work Sharp MK2 Electric Knife Sharpener, Adjustable 2-Speed
The MK2 is the broadest tool sharpener in this group: its flexible abrasive belts and edge guide support work on kitchen and pocket knives, serrated blades, scissors, axes, and garden tools. That gives it a workshop role the kitchen-focused Presto 08800 EverSharp cannot fill. Two motor speeds let the user choose a pace for different sharpening tasks, while the flexible belt can conform to different edges. Those capabilities bring a learning curve: consistent results take practice, unlike the E2’s push-button guided sharpening. The dynamic is also described as noisy, which may make it a poor fit for quiet kitchens or frequent indoor use. The MK2 makes the most sense for someone who wants one electric system for household knives and tougher tools and is willing to build skill with it. Its 3-year warranty matches the E2’s coverage.
Pros:- Supports a wide range of knife and tool types
- Two motor speeds offer control for different sharpening tasks
- Flexible abrasive belts conform to blade edges
- Includes a 3-year warranty
Cons:- Requires practice to achieve consistent results
- Noisy operation may be disruptive in a kitchen
Best for: DIY users who sharpen kitchen and pocket knives alongside serrated blades, scissors, axes, or garden tools
Not ideal for: Cooks seeking a quiet, low-learning-curve appliance dedicated to routine kitchen knife sharpening
- Model:WSKTS2
- Motor speeds:2
- Sharpening system:Flexible abrasive belts with edge guide
- Compatible tools:Kitchen and pocket knives, serrated blades, scissors, axes, and garden tools
- Included components:Abrasive belts, knife sharpener
- Warranty:3 years
- Designed and calibrated:Ashland, Oregon
Our verdict“Choose the MK2 if you want adjustable belt sharpening for kitchen knives and workshop or garden tools in one system.”
3-Stage Electric Knife Sharpener with 15° Angle Guide
This sharpener suits buyers who want a defined sharpening sequence for straight-edge steel knives: coarse, fine, and polishing stages pair with a built-in 15° guide and diamond wheels. The guide helps keep the angle consistent, while the magnetic shavings collector and non-slip feet support tidier, steadier countertop use. Its listed footprint of 10 × 4 × 4 inches is more specific and compact than the Work Sharp MK2’s belt-based tool setup. But this model is narrowly focused: it does not sharpen serrated blades or scissors, unlike the Narcissus S867, which covers both and adds ceramic knives. Its 120 W motor and stated resharpening time of as little as 30 seconds will appeal to buyers prioritizing a quick routine, though the product data does not describe speed adjustment. Pick it for straight steel blades at a set angle; skip it if your drawer includes other blade types.
Pros:- Three stages cover coarse sharpening, edge shaping, and polishing
- Built-in guide supports a consistent 15° sharpening angle
- Magnetic shavings collector supports cleaner use
- Non-slip feet and a compact 10 × 4 × 4-inch footprint suit countertop use
Cons:- Not designed for serrated blades
- Cannot sharpen scissors
Best for: Home cooks with straight-edge steel knives who want a guided 15° sharpening sequence and a compact countertop footprint
Not ideal for: Households that need one sharpener for serrated knives, ceramic blades, or scissors
- Sharpening stages:3
- Sharpening angle:15°
- Motor power:120 W
- Abrasive:Diamond wheels
- Compatible blades:Straight-edge steel knives
- Not compatible with:Serrated blades or scissors
- Dust collection:Magnetic shavings collector
- Footprint:10 × 4 × 4 inches
- Warranty:24 months
Our verdict“Choose this model for a quick, guided 15° routine on straight-edge steel knives, provided you do not need serrated or scissor sharpening.”
Chef’sChoice AngleSelect Professional Electric Knife Sharpener
The AngleSelect is the most adaptable pick here for households with knives that use different edge styles. Its guides support 15° and 20° edges, plus straight, serrated, single-bevel, and double-bevel knives. That broader compatibility gives it an edge over the Chef’sChoice 15XV, which focuses on converting knives to a 15° edge. Diamond abrasives and flexible stropping disks handle sharpening through polishing, so it can serve more than one sharpening need on the counter. The tradeoff is a larger footprint than the compact Northmas 2-Stage, and the supplied product details disagree on whether it has two or three stages. I’d choose it for versatility, while checking the stage instructions before sharpening a knife with a specialized edge.
Pros:- Supports straight, serrated, single-bevel, and double-bevel knives
- Guides accommodate both 15° and 20° edges
- Diamond abrasives and stropping disks cover sharpening and polishing
- Includes a 3-year limited warranty
Cons:- Stage count is inconsistent between the title and description
- Its 12-inch length takes more counter or storage space than the Northmas 2-Stage
Best for: Cooks with a varied collection of straight, serrated, and single- or double-bevel knives who want both 15° and 20° guides.
Not ideal for: Minimalist kitchens or owners who want a clearly documented, single-purpose sharpener with a small footprint.
- Knife types:Straight, serrated, single-bevel, and double-bevel
- Edge angles:15° and 20°
- Abrasives:100% diamond
- Stages:3-stage in description; title says 2-stage
- Dimensions:12 × 6-1/5 × 6-2/5 inches
- Warranty:3-year limited
Our verdict“Choose the AngleSelect if your knives have mixed edge styles and angles; skip it if you need a compact unit or unambiguous stage details.”
STONETIGER 4-in-1 Electric Knife Sharpener
The STONETIGER 4-in-1 stands apart from the lineup by pairing guided knife slots with support for household scissors. Its three-stage system and 6,500 RPM motor are aimed at quick countertop touch-ups, while a magnetic box catches filings and detachable parts make cleanup more manageable. The suction-cup base also helps keep the unit steady during use, a practical advantage over the Northmas 2-Stage, whose listed features do not include a stabilizing base or a filings collector. Its instructions should be read before the first pass, and the unit still needs a powered countertop spot. Buyers seeking a defined 15° edge or the broader knife-angle support of the Chef’sChoice AngleSelect should look elsewhere.
Pros:- Supports kitchen knives and household scissors
- Three guided stages help maintain a consistent sharpening path
- Magnetic collection box gathers metal filings
- Suction-cup base and detachable cleaning parts aid stable use and cleanup
Cons:- Requires countertop space and electrical power
- The manual is recommended before first use, adding setup effort
Best for: Home cooks who want one countertop appliance for routine kitchen knife sharpening and household scissors.
Not ideal for: People who need a portable sharpener, a specific edge-angle conversion, or a unit that works without mains power.
- Sharpening stages:3
- Motor speed:6,500 RPM
- Voltage:100–240V
- Sharpening time:About 20 seconds
- Compatible blades:Kitchen knives and household scissors
- Filings collection:Magnetic collection box
- Warranty:18 months
Our verdict“Pick the STONETIGER if you want knife and scissor sharpening with built-in filing collection; pass if portability or edge-angle control is your priority.”
Chef’sChoice 15XV Professional Electric Knife Sharpener, 3-Stage
The Chef’sChoice 15XV is built around one clear choice: converting traditional 20° edges into a 15° Trizor XV edge. That focus suits cooks who want a consistent, finer-angle edge across compatible straight-edge knives, with diamond abrasives for sharpening and honing and a flexible stropping stage for polishing. The stropping stage can also sharpen serrated knives, giving it more range than its angle-conversion focus might suggest. Compared with the AngleSelect, though, it does not offer a 20° guide for keeping a European or American edge as-is. Its 65–75 dB operating noise may also be noticeable in a quiet kitchen. I’d favor this over the Northmas 2-Stage when a defined three-stage process and serrated-knife support matter more than compact storage.
Pros:- Creates a 15° Trizor XV edge from traditional 20° edges
- Three stages sharpen, hone, and polish
- Flexible stropping stage can sharpen serrated knives
- Automatic angle guides simplify consistent passes
Cons:- Converts the original 20° edge rather than preserving it
- Operating noise is listed at 65–75 dB
Best for: Owners of compatible straight-edge knives who want a guided conversion from a traditional 20° edge to 15°.
Not ideal for: Cooks who want to retain a 20° edge, sharpen specialized single-bevel knives, or avoid noticeable operating noise.
- Stages:3
- Abrasives:100% diamond in stages 1 and 2; flexible abrasive stropping disks in stage 3
- Edge angle:15 degrees
- Compatible knives:Straight-edge, serrated, and Asian-style knives
- Noise level:65–75 dB
- Sharpening time:About 1 minute for first sharpening; about 10 seconds for resharpening
- Dimensions:Approximately 6.2 × 12 × 6.4 inches
- Housing:Brushed metal
- Warranty:3-year limited
Our verdict“Choose the 15XV for a guided 15° conversion and serrated-knife touch-ups; choose the AngleSelect if you need both 15° and 20° options.”
Northmas Electric Knife Sharpener, 2-Stage, Blue
The Northmas 2-Stage makes the most sense for buyers who want a basic sharpening-and-polishing setup that is easy to put away. Its compact design and 100–240V support suit kitchens with limited storage or travelers who can use the included adaptor. The manufacturer says a typical sharpening takes about 30 seconds, although the knife must be guided through the slots at a specific angle. That makes it less forgiving than the guided three-stage STONETIGER, which also adds scissor support and a filings box. Northmas offers fewer sharpening stages and its product data does not specify knife types or abrasives, so it is a simpler, less documented choice. I’d treat it as a space-saving option for routine use rather than a specialist sharpener.
Pros:- Compact body is easier to store than larger three-stage countertop models
- Two stages handle sharpening and polishing
- 100–240V support and included adaptor accommodate different power supplies
- Manufacturer lists 12-month replacement or refund service and 24-month after-sales service
Cons:- Requires the user to guide the knife at a specific angle
- Product details do not specify supported knife types or abrasive material
Best for: Apartment cooks or travelers who need a compact two-stage sharpener and can follow a manual slot angle.
Not ideal for: Owners of specialized or serrated knives who need clearly stated compatibility, or beginners who want more angle guidance.
- Brand:Northmas
- Model:QN-M868
- Type:Electric knife sharpener
- Sharpening stages:2
- Voltage:100–240V
- Color:Blue
- Included components:Adaptor and main body
- Warranty/service:12-month replacement or refund service; 24-month after-sales service
Our verdict“Pick the Northmas for compact storage and basic two-stage upkeep; choose the STONETIGER for more guidance and scissor compatibility.”
Chef’sChoice 15XV EdgeSelect Professional 3-Stage Electric Knife Sharpener
The 15XV EdgeSelect shares the 15° conversion approach of the Chef’sChoice 15XV Professional, including diamond abrasives in the first two stages and flexible guides to help control the pass. Its listed dimensions are more compact, and the manufacturer specifies about 10 seconds for resharpening after an initial sharpening of roughly one minute. That makes it a focused fit for cooks who maintain straight-edge or serrated knives and want quick touch-ups. The tradeoff is the same angle commitment: it converts traditional 20° edges to 15°, while the AngleSelect can accommodate both 15° and 20°. Its compatibility list is also narrower than the AngleSelect’s, so buyers with single-bevel knives should check that model instead.
Pros:- Three-stage system sharpens, hones, and polishes
- Diamond abrasives are used in the first two stages
- Listed resharpening time is about 10 seconds
- Flexible guides help control the sharpening angle
Cons:- Converts traditional 20° edges to 15°, which may not suit every knife
- Compatibility is limited to straight-edge and serrated knives in the supplied details
Best for: Home cooks who regularly touch up straight-edge or serrated knives and want a compact 15° conversion sharpener.
Not ideal for: Owners who want to preserve a 20° edge, sharpen single-bevel knives, or choose between multiple edge angles.
- Type:Electric knife sharpener
- Stages:3
- Abrasives:100% diamond abrasives in stages 1 and 2
- Edge angle:15 degrees
- Compatible blades:Straight-edge and serrated knives
- Sharpening time:About 1 minute for first sharpening; about 10 seconds for resharpening
- Dimensions:10 × 4.25 × 4.25 inches
- Warranty:3-year limited
Our verdict“Choose the EdgeSelect for quick upkeep of compatible knives at a 15° edge; choose the AngleSelect for broader edge-angle and knife-style support.”
Narcissus QN-M866 2-Stage Electric Knife Sharpener with Scissors Sharpener
The QN-M866 earns its place for households that want one countertop tool for straight-edge kitchen knives and scissors. Its coarse and fine stages handle sharpening and polishing, while a magnetic collection box catches metal filings for simpler cleanup. Compared with the Presto 08810, it has fewer sharpening stages and no stated blade-thickness adjustments, so it offers less tailoring for different knives. Its scissors slot fills a gap the Presto’s listed functions do not cover. The 30-watt motor is rated for over an hour of continuous operation, and 100–240V input adds flexibility across power systems. The tradeoff is narrow compatibility: it is designed for straight blades, and the maker recommends watching its video before first use to learn the technique.
Pros:- Coarse and fine stages sharpen and polish straight-edge knives
- Dedicated slot adds scissors sharpening
- Magnetic collection box helps gather metal filings
- Supports over an hour of continuous operation
Cons:- Designed for straight-blade knives, limiting its usefulness for serrated edges
- First use may require consulting the product video for technique
Best for: Home cooks who sharpen straight-edge kitchen knives and want a dedicated slot for household scissors
Not ideal for: Owners of serrated knives or shoppers who want adjustable guides for different blade thicknesses
- Brand:Narcissus
- Model:QN-M866
- Sharpening stages:2
- Motor power:30 watts
- Input voltage:100–240V
- Compatible knives:Straight-blade chef, slicing, and santoku knives
- Additional function:Scissors sharpening slot
- Dust collection:Magnetic metal dust collection box
- Warranty and service:12-month replacement or refund policy; 24-month after-sales service
Our verdict“Choose the QN-M866 if you want a two-stage kitchen sharpener that also handles scissors and you mainly own straight-edge knives.”
Presto 08810 Professional EverSharp Electric Knife Sharpener
The Presto 08810 stands out for cooks who sharpen knives with different blade thicknesses. Its guides adjust for thick, medium, and thin blades, giving it a more tailored setup than the fixed-angle Narcissus S809. A three-stage system finishes with an extra-fine ceramic honing wheel, which refines the edge after sharpening. The listed compatibility includes kitchen and sport knives, including Santoku blades, so it reaches beyond a kitchen-only routine. The tradeoff is that the product data does not specify features such as dust collection, scissors sharpening, or voltage range; buyers seeking those details may prefer models like the QN-M866, which explicitly lists a scissors slot and magnetic filing box. This is the more suitable pick when blade thickness is the main variable to manage.
Pros:- Three-stage sharpening system includes a honing step
- Adjustable guides fit thick, medium, and thin blades
- Extra-fine ceramic wheel hones the edge
- Listed for kitchen and sport knives, including Santoku
Cons:- The supplied product data does not state whether it sharpens serrated knives
- The listed specifications do not identify a dust collection feature
- No scissors sharpening function is specified
Best for: Home cooks with a mix of thin and thick kitchen or sport knives who want guide settings matched to blade thickness
Not ideal for: Buyers who need a stated scissors slot, dust collection system, or serrated-knife compatibility
- Brand:Presto
- Model:08810
- Sharpening system:3-stage
- Compatible knives:Kitchen and sport knives, including Santoku
- Blade thickness settings:Thick, medium, and thin
- Honing wheel:Extra-fine-grit ceramic
Our verdict“Pick the Presto 08810 if adjustable blade-thickness guides matter more to you than extra functions such as scissors sharpening or filing collection.”
Chef’sChoice UltraHone 2-Stage Electric Knife Sharpener, White
The UltraHone is a focused choice for buyers who want diamond abrasives and angle guides in a two-stage sharpener. It is listed for 20-degree straight-edge and serrated knives, giving it broader edge compatibility than the straight-blade-only Narcissus QN-M866. The two sharpening and honing stages aim to leave a durable edge, and a magnetic pad helps catch residue during cleanup. Its limitation is especially relevant for serrated-knife owners: the manufacturer recommends other Chef’sChoice models for complete serrated sharpening. Compared with the Narcissus S809, which lists three stages and compatibility with ceramic blades and additional tools, the UltraHone has a more limited feature set. It makes most sense when diamond sharpening for standard kitchen edges is the priority, with occasional serrated-knife upkeep rather than full serration restoration.
Pros:- Uses 100% diamond abrasives
- Precision angle guides support consistent sharpening
- Listed for both straight-edge and serrated knives
- Magnetic pad helps collect residue
Cons:- Complete serrated-knife sharpening is recommended with other Chef’sChoice models
- Two stages provide fewer finishing steps than the three-stage Narcissus S809
- The listed compatibility is limited to 20-degree edges
Best for: Home cooks with 20-degree straight-edge knives and some serrated blades who want diamond abrasives and guided sharpening
Not ideal for: Buyers who need complete serrated-knife sharpening in one unit or want ceramic-blade and tool compatibility
- Brand:Chef’sChoice
- Model:0312000
- Sharpening stages:2
- Abrasive:100% diamond
- Knife compatibility:20-degree straight-edge and serrated knives
- Color:White
- Included components:Electric knife sharpener
Our verdict“Choose the UltraHone for diamond-guided sharpening of 20-degree straight knives and light serrated upkeep, but not for full serration restoration.”
Narcissus S809 3-Stage Electric Knife Sharpener
The S809’s distinguishing feature is its stated compatibility with ceramic as well as stainless steel knives, making it a specialized alternative to the steel-focused Presto 08810. Its diamond wheels work across three stages—coarse, fine, and polishing—and the fixed 20-degree angle helps guide the blade through the process. The open port also accommodates listed tools such as scissors and axes, giving it a broader task range than the two-stage QN-M866. A removable metal-dust box supports cleanup, and the unit is specified for over an hour of continuous operation. Buyers trade adjustability for simplicity: the angle is fixed, the sharpening method may take practice, and the product data gives no dimensions or weight for planning counter or storage space.
Pros:- Three stages cover edge repair, honing, and polishing
- Diamond abrasives and fixed 20-degree angle guide the sharpening process
- Listed for stainless steel and ceramic blades
- Removable metal-dust collection box supports cleanup
Cons:- Fixed 20-degree angle does not offer adjustment for other edge angles
- Manual consultation may be needed to learn the sharpening technique
- Dimensions and weight are not specified in the product data
Best for: Households with ceramic and stainless steel straight-edge knives that want multiple finishing stages and a fixed sharpening guide
Not ideal for: Buyers who want an adjustable sharpening angle or need to confirm the unit’s size before purchase
- Brand:Narcissus
- Model:S809
- Sharpening stages:3
- Abrasive material:Diamond
- Sharpening angle:20 degrees
- Compatible blades:Straight, serrated, stainless steel, and ceramic knives
- Additional tools:Scissors and axes
- Voltage and operation:100–240V; over 1 hour continuous operation
- Warranty and support:12-month replacement or refund policy; 24-month technical assistance
Our verdict“The S809 suits cooks who need a three-stage sharpener for ceramic and steel knives and are comfortable with a fixed 20-degree guide.”
Work Sharp MK.2 Electric Knife and Tool Sharpener
The MK.2 is the broadest tool sharpener in this group: its flexible belts and two-speed motor cover kitchen and pocket knives, serrated blades, scissors, axes, lawn mower blades, and garden tools. That range sets it apart from the Presto 08810, which is specified for kitchen and sport knives and uses fixed sharpening stages. An edge guide supports the blade to its tip, while the two speeds give buyers a way to match control to the task. Replacement belts are included, and the three-year warranty is longer than the support periods listed for the Narcissus models. Its breadth comes with a tradeoff: this is not a dedicated kitchen-only system with a stated sequence of coarse, fine, and polishing stages, so cooks seeking a narrowly guided countertop routine may prefer the Chef’sChoice UltraHone.
Pros:- Handles a wide range of knives and outdoor tools
- Two speeds offer control for different sharpening tasks
- Edge guide supports the blade through its tip
- Includes replacement belts and a three-year warranty
Cons:- Its broad tool focus may be more than a kitchen-only user needs
- The product data does not specify a staged honing or polishing sequence
Best for: Homeowners and outdoor users who want one powered sharpener for kitchen knives, pocket knives, scissors, axes, and garden tools
Not ideal for: Cooks who only sharpen kitchen knives and prefer a dedicated staged system with a clearly specified honing sequence

Our verdict“Choose the MK.2 if you want one belt sharpener for kitchen knives and outdoor tools, while dedicated kitchen sharpening is your main priority.”
How We Picked
I compared these sharpeners on the factors that change the buying decision: supported edge angles, number and purpose of sharpening stages, ease of guiding a blade, and whether the machine is designed for kitchen knives or broader tool use. I also weighed practical upkeep, including how clearly the sharpening sequence is explained and whether the format seems manageable for occasional home use. A higher stage count mattered only when it added a useful sharpening step rather than complexity for its own sake.
The ranking favors a capable kitchen sharpener with clear guidance and useful edge options, which puts the Chef’sChoice 15XV EdgeSelect first for its combination of three stages and 15-degree capability. Picks such as the Work Sharp E2 and Presto EverSharp rank well for simpler routines and value, while adjustable or multipurpose models rank higher for buyers who need their extra range and lower for cooks seeking a dedicated, uncomplicated kitchen appliance. Since product names alone do not establish compatibility with every blade, I treat specialty claims as a reason to check the manufacturer’s guidance before sharpening premium, serrated, or unusually shaped knives.
Factors to Consider When Choosing Electric Knife Sharpeners
Before choosing a model, start with your knives and sharpening habits. An electric sharpener can save effort, but the wrong angle or an unsuitable guide can remove more steel than your blades need. These broader checks help match the machine to your kitchen, how often you sharpen, and how much control you want.
Match the Sharpener’s Angle to Your Knives
Knife edges are ground at particular angles, and changing that angle can alter how the blade cuts and how much steel sharpening removes. A 15-degree option may suit some thinner-edged knives, while other kitchen knives use a different geometry. Check the knife maker’s sharpening guidance before buying, especially if your collection includes premium Japanese-style blades. A sharpener that offers more than one angle can cover varied knives, but extra settings are useful only if you know which setting belongs to which blade. Avoid choosing by the smallest angle number alone; edge design and intended use matter together. If your knives share one angle, a dedicated guided model may be easier to use than a more adjustable machine.
Choose Stages for Your Sharpening Routine
Sharpening stages usually separate heavier edge shaping from finer honing or polishing, though the exact roles depend on the model. If you maintain knives regularly, you may need the finishing steps more often than a full reshaping pass. Letting a dull blade go for a long time can make a repair stage more relevant, but using it routinely may remove steel unnecessarily. More stages do not automatically mean a better result for every cook. Read the manual to learn when each stage is intended and how many passes to make. If you prefer a simple routine, favor a clearly labeled sequence over a machine with extra steps you may rarely use.
Be Realistic About Blade Compatibility
Electric sharpeners are not universal solutions for every knife shape or edge. Serrated blades, single-bevel knives, very short blades, and unusual profiles may require a different method or a model-specific procedure. Before purchase, check the maker’s compatibility list rather than relying on broad phrases such as “kitchen knives.” A pull-through guide can make straight-edged knives easier to position, yet it may not reach the edge geometry of specialty blades. Sharpening a blade in an incompatible slot can damage its edge or produce uneven contact. If your collection includes specialty knives, choosing a dedicated manual service or a compatible sharpening system may be the safer fit.
Decide Whether Versatility Is Worth the Space
Some sharpeners are built for kitchen knives, while others extend to scissors or outdoor and workshop tools. That wider range can reduce the number of devices you keep, but each use may require a different belt, guide, or technique. A compact kitchen unit is often easier to store and straightforward to bring out for routine maintenance. A tool-oriented system can suit a household that sharpens more than chef’s knives, especially when adjustable speed helps match the job. Think through where the sharpener will live and which extra tasks you will actually do. If the added functions remain unused, a versatile machine may bring extra setup without improving your daily cooking routine.
Favor Control and Clear Instructions Over Speed Claims
Motorized sharpening moves quickly, which makes steady blade movement and sensible pass counts important. Look for guidance on blade position, stroke direction, and pressure; clear instructions can matter more to a beginner than another speed setting. Adjustable speed can help with varied tasks, but it also gives the operator another decision to make. Keep the blade moving as directed and avoid pressing hard, since pressure can cause excess material removal or heat buildup. If you are new to sharpening, practice the prescribed routine on a less cherished compatible knife before working on an expensive blade. A slower, well-guided approach can be more useful than a fast machine that leaves you unsure how to handle each pass.
Plan for Maintenance and Long-Term Ownership
A sharpener’s abrasives wear with use, and replacement parts or cleaning needs can affect how convenient it remains over time. Check the manual for abrasive replacement, cleaning instructions, and any limits on continuous operation. A model with an easy-to-follow routine may be simpler to maintain even if its initial feature list is shorter. Keep the machine clean and unplugged while following the maker’s care instructions. If you sharpen only a few household knives, an elaborate system may not earn its storage space. Buyers who maintain a large collection or several types of blades may find a more serviceable, adaptable design worth the added setup.
Frequently Asked Questions
Can I use an electric sharpener on every knife in my kitchen?
No single electric sharpener should be assumed to fit every blade. Straight-edged kitchen knives are the most common match, while serrated, single-bevel, short, or unusually shaped blades may need a specific method. Check both the knife maker’s guidance and the sharpener’s compatibility instructions before using a slot. If the guidance is unclear, avoid experimenting on a costly knife. A separate manual tool or professional service may suit specialty blades better.
Should I choose a 15-degree sharpener if I want the sharpest edge?
A smaller angle does not automatically make an edge better for your needs. The right angle depends on the knife’s original geometry, steel, and intended work, and changing it can remove extra material. Some knives are designed for a 15-degree edge, while others should retain a different angle. Confirm the maker’s recommendation before selecting a sharpener based on its angle setting. If your collection mixes edge types, a compatible adjustable model may be more useful than one fixed angle.
How often should I use an electric sharpener?
There is no single schedule because sharpening frequency depends on how often you cook, the board and cutting technique, and the knife steel. Use the sharpener’s honing or maintenance stage according to its instructions when the knife’s cutting performance begins to fade. Save heavier grinding stages for edges that need reshaping, since frequent material removal shortens a blade’s usable life. A honing rod or other maintenance method may keep an edge working between sharpening sessions. Let the knife’s performance and the manual guide the routine rather than sharpening on a fixed calendar.
Is a three-stage sharpener worth choosing over a two-stage model?
It can be, if the additional stage has a clear role in the maker’s process and you will follow that sequence. A three-stage system may separate shaping and finishing more distinctly, while a two-stage design can be simpler for routine home care. Stage count alone does not tell you how well a sharpener fits a particular knife. Compare the supported angle, intended blade types, and directions for each stage. For a small set of everyday knives, ease of correct use may matter more than an extra step.
When does a multipurpose knife sharpener make more sense than a kitchen-only model?
Choose a multipurpose system when you expect to sharpen scissors, outdoor blades, or workshop tools as well as kitchen knives. It can consolidate several tasks, though different tools may call for different guides, abrasives, and handling. If you mainly maintain chef’s knives, a kitchen-focused sharpener is often easier to store and operate. Before buying, check that the model explicitly supports the extra tool types you own. The broader feature set is useful when it matches regular tasks, not simply because it lists more uses.
Conclusion
For most cooks seeking a capable dedicated kitchen sharpener, I recommend the Chef’sChoice 15XV EdgeSelect as the best overall choice, particularly if its 15-degree option matches your knives. Buyers who want a simple routine should look at the Work Sharp E2, while the Presto 08800 EverSharp is my value-oriented pick for straightforward home sharpening. Beginners can favor a guided kitchen model with clear stage instructions over an adjustable tool system. For premium edge-angle flexibility, compare the Chef’sChoice 15XV EdgeSelect with the AngleSelect and confirm the settings suit your blades. If you also sharpen scissors or workshop tools, consider the Narcissus QN-M866 or Work Sharp MK2; their added range makes the most sense when those extra tasks are part of your routine.
