Top 10 Electric Knife Sharpeners in 2027 — Best Overall + Best Value

Direct Answer

The best overall electric knife sharpener in 2027 is the Chef'sChoice Trizor 15XV (Model 15XV) at $169, a 3-stage, 100%-diamond machine that converts a dull 20-degree factory edge into a durable 15-degree triple-bevel edge in about a minute and handles serrated blades too.

The best value pick is the Presto EverSharp 08800 at $29, a no-frills 2-stage Sapphirite sharpener that gets most home knives genuinely sharp for under thirty dollars. This list is for home cooks and serious hobbyists who want a fast, repeatable edge without learning to freehand on whetstones — whether you own a drawer of German Western knives, a few Japanese 15-degree blades, or a mix of both.

How We Ranked the Top 10

We weighted real-world sharpening results over marketing claims, drawing on long-run testing from America's Test Kitchen, Wirecutter, Serious Eats, CNET, and The Spruce Eats, then cross-checked specs against each maker's own sheets from Chef'sChoice, Work Sharp, Presto, and Wusthof. The scoring breakdown:

• Sharpening quality & edge — 30%
• Ease of use / consistency — 20%
• Blade compatibility (angle, serrated) — 15%
• Build & durability — 15%
• Speed & stages — 10%
• Price-to-performance — 10%

We favored machines with angle-guided slots (so the result does not depend on your hand), diamond or quality ceramic abrasives, and a polishing/honing stage rather than a single grinding wheel that just eats steel.

1. Chef'sChoice Trizor 15XV (Model 15XV) 🏆 BEST OVERALL

Price: $169 | Best for: anyone who wants the sharpest, most repeatable edge with the least skill

This is the machine that wins nearly every editorial roundup, and for good reason. The 15XV is a 3-stage electric sharpener running 100% diamond abrasives through spring-guided slots, and it re-profiles a standard 20-degree edge into a stronger 15-degree Trizor triple-bevel that slices and dices with noticeably less effort.

Stage 1 shapes the bevel with coarse diamonds, Stage 2 sharpens, and Stage 3 strops and polishes; the flexible stropping disk also puts a usable microscopically serrated edge that grips tomatoes and bread. It is heavy, stable, and built to last years of regular use, and a full sharpen takes roughly a minute with quick touch-ups after that.

Pros:

• Best, most consistent edge of any pull-through electric we tested
• 100% diamond, 3 stages including a real polishing pass
• Angle guides remove user error almost entirely
• Handles serrated knives in the polishing stage

Cons:

• Pricey, and the 15-degree conversion removes a fair amount of metal the first time
• Overkill if you only own a couple of cheap knives

Verdict: The default recommendation for almost every home cook — buy it once and your knives stay frighteningly sharp.

2. Work Sharp Culinary E5

Price: $235 | Best for: cooks who want belt-sharpening speed plus a built-in honing rod

The Work Sharp Culinary E5 takes a different path: instead of diamond wheels it uses a flexible abrasive belt that shapes, sharpens, and refines in under 90 seconds, plus a ceramic honing rod built into the body for between-sharpening touch-ups. The single belt behaves like multiple grits because the machine varies speed across its three settings (shape, sharpen, hone), and a small built-in vacuum pulls swarf off your counter.

Edges come off keen and the guided slots keep the bevel honest, making it a strong runner-up to the Chef'sChoice for people who like the belt feel.

Pros:

• Fast belt system with a genuine honing stage
• Built-in ceramic rod for quick maintenance
• Vacuum collection keeps the workspace clean

Cons:

• Most expensive pick here, and belts are a consumable you replace over time

Verdict: A premium, fast alternative if the belt-and-honing-rod combo appeals more than diamond wheels.

3. Chef'sChoice 1520 AngleSelect

Price: $159 | Best for: households mixing 15-degree Japanese and 20-degree Western knives

If your drawer holds both angle styles, the 1520 AngleSelect is the smart buy. It is a 3-stage, 100% diamond electric sharpener with a selectable angle: the slots sharpen 15-degree edges in one path and 20-degree edges in another, with a final stropping stage for polish.

That flexibility means you do not have to force a Japanese gyuto down to a Western angle or vice versa, and it still handles serrated blades. Build quality matches the 15XV, and America's Test Kitchen specifically recommends it for mixed collections.

Pros:

• Switchable 15 and 20-degree sharpening
• 3 diamond stages with real polishing
• Serrated-capable and very durable

Cons:

• Costs nearly as much as the 15XV without the single-minded 15-degree refinement

Verdict: The pick when one machine has to serve both Japanese and German knives under one roof.

4. Wusthof Easy Edge

Price: $179 | Best for: Wusthof and other German-knife owners wanting brand-matched angles

Built around Wusthof's Precision Edge Technology (PEtec), the Easy Edge is a 3-stage electric sharpener whose guided discs sharpen, hone, and strop at the 14-degree angle Wusthof grinds its modern blades to. The motorized abrasive belts pull a tired edge back to keen quickly, and the matched angle means you are not fighting your knife's factory geometry.

It is a clean, well-built unit that pairs naturally with a Wusthof block, though it works on other Western knives too.

Pros:

• Brand-matched 14-degree geometry for German knives
• Three stages: sharpen, hone, strop
• Quick and easy for large chef's knives

Cons:

• Premium price, and the fixed angle suits Western blades better than thin Japanese ones

Verdict: The obvious choice if you already own Wusthof knives and want the maker's own angle.

5. Presto EverSharp 08800 💎 BEST VALUE

Price: $29 | Best for: budget shoppers who just want sharp everyday knives, fast

For under thirty dollars the Presto EverSharp punches far above its price. It is a 2-stage electric sharpener with rapidly spinning Sapphirite grinding wheels — the same abrasive used in professional shops — that precision-grind a 20-degree bevel in Stage 1 and fine-hone the edge in Stage 2.

The slots are angle-guided so you simply draw the blade through, and most kitchen knives come out cleanly sharp in a couple of passes. It does not polish to the mirror finish of a Chef'sChoice and skips serrated blades, but for the money it is the easiest sharp-knife upgrade you can buy.

Pros:

• Under $30 with surprisingly good results
• Sapphirite wheels grind fast
• Guided slots make it foolproof
• Compact and light for small kitchens

Cons:

• No serrated support and no true polishing stage
• Grinding wheels are aggressive on metal over time

Verdict: The runaway value pick — genuinely sharp knives for the price of a cheap chef's knife.

6. Chef'sChoice Hybrid 220

Price: $45 | Best for: people who want electric grinding plus manual control in one body

The Hybrid 220 is a clever 3-stage design that combines a powered diamond sharpening stage with a manual stropping/finishing stage in the same unit. Stage 1 uses the motor and diamonds to do the heavy edge work, then you finish by hand through the manual slots for control over the final polish, all at a 20-degree Western angle.

It is far cheaper than the flagship Chef'sChoice machines and a good step up from a pure budget grinder for someone who likes a little hands-on finishing.

Pros:

• Electric diamond stage plus manual finish stage
• Diamond abrasives at a low price
• Compact countertop footprint

Cons:

• Fixed 20-degree angle; not for thin Japanese edges
• Less refined final edge than the 15XV or 1520

Verdict: A budget-friendly hybrid for cooks who want power sharpening with manual finishing control.

7. Work Sharp Culinary E2

Price: $50 | Best for: first-time electric sharpener buyers on a tight budget

The Work Sharp Culinary E2 brings guided, abrasive-disk sharpening to an entry price. It uses flexible abrasive disks in a guided pull-through slot plus a ceramic honing path, so beginners get angle control without thinking about it. Results are usable rather than spectacular — testers noted a somewhat low, occasionally uneven bevel — but for someone moving up from a dull drawer of knives it is a real improvement and a fraction of the E5's cost.

Pros:

• Guided slots keep beginners honest
• Ceramic honing path for touch-ups
• Affordable entry point to the brand

Cons:

• Edge can come out uneven compared with pricier units
• Less aggressive on very dull or damaged blades

Verdict: A fine starter electric for under fifty dollars, with room to upgrade later.

8. Smith's / KitchenIQ 50029 Compact Electric

Price: $25 | Best for: tiny kitchens and shoppers who want the cheapest powered option

This 2-stage compact electric from Smith's (KitchenIQ) is about as small and inexpensive as a powered sharpener gets. It pairs an electric coarse stage with a manual fine stage and a blade guide to set the angle for you on straight-edge knives. It will not transform a knife the way a diamond Chef'sChoice does, but it lives in a drawer, costs about the price of two coffees, and keeps everyday blades cutting.

Pros:

• Very cheap and drawer-sized
• Electric coarse + manual fine stages
• Blade guide for angle consistency

Cons:

• Straight-edge only; no serrated and no polish
• Lightweight build; not for heavy or daily kitchen use

Verdict: The pick when space and budget are both extremely tight.

9. Chef'sChoice 312 UltraHone

Price: $60 | Best for: owners of all-20-degree Western and serrated knives

The Chef'sChoice 312 UltraHone is a focused 2-stage electric built specifically for 20-degree straight-edge and serrated knives. Stage 1 sharpens with abrasive disks and Stage 2 hones and polishes, and crucially it does a good job on serrated blades, which most cheaper units ignore entirely.

If your kitchen is all classic German-angle knives plus a bread knife, this targeted machine costs less than the flagship models and covers exactly what you own.

Pros:

• Genuinely sharpens serrated knives
• Two stages including a polishing pass
• Solid Chef'sChoice build at a mid price

Cons:

• 20-degree only — wrong tool for 15-degree Japanese blades
• No multi-angle flexibility

Verdict: A smart mid-priced choice for an all-Western, serrated-heavy knife drawer.

10. AnySharp Pro

Price: $20 | Best for: manual-sharpener fans who want one reliable, grippy budget tool

Rounding out the list is the AnySharp Pro, a manual (non-electric) sharpener included here as the dependable budget benchmark every electric should beat. Its single tungsten carbide slot sits at a fixed angle, and a PowerGrip suction base locks it to the counter so you can pull the knife through one-handed and safely.

It removes a fair bit of metal and will not polish, but it is nearly indestructible, costs almost nothing, and revives a dull blade in seconds.

Pros:

• Suction base holds firm for safe one-handed use
• Tungsten carbide edge bites hard on dull steel
• Tiny and almost unbreakable

Cons:

• Manual and aggressive; no fine polish and no serrated support

Verdict: The honest budget fallback — not electric, but the best cheap manual to keep in any drawer.

Buyer Decision Tree — Which One's Right for You?

What to Look For When Buying an Electric Knife Sharpener

• Number of stages — a coarse grinding stage shapes the edge, but you want at least one honing/stropping stage to polish it; single-stage grinders leave a rough, fast-dulling edge.
• Sharpening angle for your knives — Western/German knives are typically 20 degrees (Wusthof's modern PEtec is 14), Japanese knives 15 degrees; match the machine or use an angle-selectable model like the 1520.
• Serrated capability — most cheap units skip it; the 15XV, 1520, and 312 handle serrated blades.
• Abrasive type — 100% diamond lasts longest and cuts fastest; Sapphirite/ceramic wheels are good and cheaper; tungsten carbide is aggressive and removes the most metal.
• Ease and consistency — angle-guided slots matter more than almost anything, because they make the result repeatable regardless of your skill.
• Build & durability — a heavy, stable base that does not walk across the counter signals a machine you will keep for years.
• Metal removal aggressiveness — gentler is better for long knife life; coarse carbide and aggressive grinders shorten a blade faster.

What matters less than marketing implies: exact stated grit numbers, mirror-polish claims, and the precise count of "professional" stages. A solid two-stage diamond or Sapphirite machine with good guides outperforms a flashy multi-stage unit with sloppy slots, so weigh real test results over the spec sheet.

FAQ

Are electric knife sharpeners bad for your knives? They remove more metal than whetstones, so an overly aggressive grinder will shorten a blade over years. But a guided diamond machine like the Chef'sChoice 15XV is gentle and consistent, and for most home cooks the trade-off of always-sharp knives is well worth it.

What angle should I sharpen my knives at? Western and German knives are usually 20 degrees per side (Wusthof's PEtec line is 14), while Japanese knives are typically 15 degrees. If you own both, get an angle-selectable sharpener like the Chef'sChoice 1520.

Can electric sharpeners handle serrated knives? Some can. The Chef'sChoice 15XV, 1520, and 312 sharpen serrated blades in their polishing stages, but budget units like the Presto EverSharp are straight-edge only.

How often should I sharpen versus hone? Hone (realign the edge) every few uses with a rod, and run a full sharpening every few weeks to months depending on use. Many electric units, like the Work Sharp E5, include a honing stage for between-sharpening upkeep.

Is a $30 sharpener really good enough? For everyday home knives, yes — the Presto EverSharp gets blades genuinely sharp. Step up to a diamond multi-stage machine only if you own nicer knives, want a polished edge, or need serrated and multi-angle support.

Electric or manual — which is better? Electric is faster and more consistent thanks to powered angle-guided slots; manual sharpeners like the AnySharp Pro are cheaper and travel-friendly but depend more on technique. For a busy kitchen, electric wins.

Bottom Line

For nearly every home cook, the Chef'sChoice Trizor 15XV at $169 is the electric knife sharpener to buy — a 3-stage, 100%-diamond machine that delivers the sharpest, most repeatable edge with almost no skill required. If you would rather spend a fraction of that, the Presto EverSharp 08800 at $29 is the standout value, turning dull everyday knives razor-sharp for under thirty dollars.

If your needs are more specific — mixed knife angles, Wusthof blades, serrated knives, or a belt system — run through the decision tree above to land on the right pick.
