The best electric knife sharpener for your knives

Electric sharpeners trade a little control for a lot of speed. The best ones hold the angle with spring guides, use diamond or fine ceramic stages, and finish with a hone or strop. Here are seven, from a budget Presto to an adjustable belt grinder.

The best electric knife sharpener for most kitchens is the Chef'sChoice 15XV: three stages with diamond abrasives and a stropping finish, a consistent 15° edge, and support for serrated knives. If your block mixes German and Japanese knives, the Chef'sChoice AngleSelect adds a 20° setting. On a budget, the Presto 08800 has nearly 19,000 ratings. And if you also sharpen pocket knives and tools, the Work Sharp Ken Onion Mk2 adjusts from 15° to 30°.

How electric sharpeners work

The stages of a typical electric knife sharpener Three slots from left to right: stage one coarse, which removes metal to form a new bevel and is used rarely; stage two fine, which refines the edge; stage three hone or strop, which polishes and removes the burr and is used most often. 1 · COARSE new bevel 2 · FINE refine 3 · HONE / STROP polish, deburr use rarely when dull use most often
A typical layout. Most knife damage from electric sharpeners comes from overusing stage one.

Spring-loaded or fixed guides hold the blade at the angle while motor-driven wheels or belts grind. Wheel models (Chef'sChoice, Presto) are fastest and easiest; belt models (Work Sharp) handle a wider range of blades, including tools, and some let you adjust the angle.

Chef'sChoice 15XV EdgeSelect

The 15XV is the benchmark home electric. Two stages plated with 100% diamond abrasives sharpen and hone, and a patented flexible third stage strops the edge.

It's the best seller here with 2,000+ purchases last month and 14,000+ ratings.

Presto 08800 EverSharp

Buying guide

Match the angle to your knives

Many Japanese knives are sharpened around 15° per side and many German knives around 20°. A 15° electric will thin out a 20° German edge, which cuts better but is a little less durable; a two-angle model avoids the compromise. Check your knife maker's recommendation and see the angle chart.

Look for a fine finishing stage

A ceramic hone or flexible strop stage gives a cleaner edge and is the stage you'll use most. Every pick here has one, except that belt models rely on fine belts.

Serrated and single-bevel knives

Check the listing. For serrated knives without electric support, see how to sharpen a serrated knife. For single-bevel Japanese knives, a whetstone is still the safest choice; see sharpeners for Japanese knives.

Wheel vs belt

Wheel models are simpler and best for kitchen knives. Belt models handle pocket knives, hunting knives, scissors and tools, and some offer adjustable angles, but need more care.

Getting the best from an electric sharpener

  • Start at the finest stage and only go coarser if the knife doesn't respond.
  • Pull at a steady speed with no downward pressure; let the guides do the work.
  • Alternate slots or sides evenly as the instructions direct.
  • Lift the handle slightly at the tip so the curve is sharpened.
  • Empty the metal dust as the maker recommends.

If you'd rather not go electric

A guided manual system like the Work Sharp Precision Adjust removes less metal and gives you any angle from 15° to 30°; a 1000/6000 whetstone gives the most refined edge. Compare in whetstone vs knife sharpener. For a premium powered option with a wide angle range, see the Tormek T-1.

The bottom line

The Chef'sChoice 15XV is the best electric knife sharpener for most kitchens. Choose the Chef'sChoice AngleSelect for mixed German and Japanese sets, the Presto 08800 on a budget, and the Work Sharp Ken Onion Mk2 if you sharpen pocket knives and tools too.

Questions people ask

Are electric knife sharpeners bad for knives?
Good ones aren't, used correctly. Electric sharpeners remove more metal than a whetstone, mostly in their coarse stage, so use that stage only when a knife is truly dull and use the fine stage for regular touch-ups. Avoid them on single-bevel Japanese knives unless the maker says the model supports them.
What is the best electric knife sharpener for home use?
The Chef'sChoice 15XV is the best all-round choice: three stages, 100% diamond abrasives in the first two, a stropping third stage and a 15-degree edge. If you own both German and Japanese knives, the Chef'sChoice AngleSelect offers 15 and 20 degree settings.
Can electric sharpeners sharpen serrated knives?
Some can. The Chef'sChoice 15XV and AngleSelect, the Work Sharp Ken Onion Mk2 and the Work Sharp E2 list serrated blades as supported. The Presto 08800 is listed for non-serrated blades.
What angle do electric knife sharpeners use?
It depends on the model. The Chef'sChoice 15XV sharpens at 15 degrees; the AngleSelect offers 15 and 20; the Work Sharp Ken Onion Mk2 adjusts from 15 to 30. Many Japanese knives sit around 15 degrees per side and many German knives around 20; check your knife maker's recommendation.
Is an electric sharpener better than a whetstone?
It's faster and needs no skill, which means many people actually keep their knives sharp with it. A whetstone gives a more refined edge and removes less metal. See our whetstone vs knife sharpener guide for the full comparison.
How often should I use an electric knife sharpener?
Use the fine or honing stage whenever the knife feels less sharp, often weekly for a busy kitchen. Use the coarse stage only when the knife is truly dull, perhaps a few times a year.
