The very best sharpener I used whereas testing was the $150 Chef’s Alternative Trizor XV, a cumbersome gadget with three separate tracks for bringing uninteresting knives to a super-sharp 15-degree edge (many American knives are sharpened to a 20-degree angle). The Trizor additionally comes with thorough and useful instructions to be used — explaining unfamiliar phrases and processes in simple methods. Plus, magnets on the sharpening tracks hold your blade angled appropriately, so danger of creating errors whereas sharpening a uninteresting blade on the diamond abrasive sharpeners is fairly minimal. 

The outcomes of my testing had been spectacular. The sharp blade and easy edge produced by the gadget meant I may slice by way of a tomato with out squashing it or tearing the pores and skin due to inconsistencies throughout the size of the sting.

The one draw back of the Trizor sharpener is its premium value ($150 is greater than most individuals pay for a chef’s knife, not to mention the tool that sharpens it) and its cumbersome profile. However when you’ve got loads of counter area or don’t thoughts storing it in a cupboard, the Trizor is the best-performing gadget round.

When you’re much less excited by sustaining an ideal edge in your knife blade, and as a substitute need an reasonably priced, “good-enough” different, the $6 KitchenIQ 2 Stage Knife Sharpener may be for you. No, it received’t totally resurrect an outdated, uninteresting blade, however this sharpener may also help sustain a greater edge than normal with just some passes by way of the sharpening tracks every day.

The KitchenIQ additionally consists of two tracks: a rough sharpener for setting the sting, and a superb sharpener for ending it. When in comparison with different compact, non-electric merchandise, just like the $25 Anysharp Professional with solely a rough sharpener or the poorly performing $eight Kadell three Levels sharpener, the KitchenIQ stands out. 


To check our knife sharpeners, we acquired eight similar chef’s knives and dulled them utilizing a Dremel. They nonetheless may reduce tomatoes and pineapples (our two testing fruits), however not cleanly; primarily, we needed our knives to behave like chef’s knives which have seen years of use with out a lot maintenance.

I examined the knives earlier than sharpening them to make sure all of them carried out about as poorly as we needed them to, paired every with a sharpener and labeled accordingly. I then adopted the instructions for every sharpener. Some sharpeners prompt passing the blade by way of “till sharp,” and I did so till the enhancements appeared negligible. Different sharpeners had been extra prescriptive, and I adopted the instructions exactly.

After sharpening, I examined every knife, how a lot it squashed a ripe tomato and tore its pores and skin whereas slicing, in addition to how simply it sliced pores and skin from a ripe pineapple. I rated the reduce with every fruit out of 10, noting my particular observations. The first objectives right here had been to see how sharp the sting turned and the way easy it was throughout its size: a pointy blade shouldn’t squash a tomato, and a easy blade shouldn’t tear its pores and skin. A pineapple would check the identical results in a better stress context — chopping by way of a sturdy fruit in a non-straight sample.

Which is the very best knife sharpener for you?

An important ingredient of a knife sharpener is its skill to sharpen an edge throughout the size of a blade. That mentioned, loads of different elements may make different gadgets a greater match for you. Listed below are a few of these elements:

  • Skill to sharpen various kinds of knives
  • Cleanliness
  • Sound

Typically, sharpening a serrated blade particularly requires a serrated knife sharpener, however you continue to might wish to sharpen straight paring knives, boning knives, a fillet knife, cleavers or utility blades (or perhaps a pocket knife or looking knife). Whereas the Chef’s Alternative sharpener is the very best for chef’s knives, each the Presto Three Stage and Work Sharp gadgets supply a bit extra flexibility for various blades. Presto, as an example, can alter its slots to information totally different blades extra successfully. Work Sharp makes use of attachments and belts of various coarseness for kitchen knives, pocket knives or scissors — a modular method which will delay informal cooks, however will probably enchantment to DIY lovers.


Regardless of honest outcomes, the Work Sharp seems far more at house in a storage than on a kitchen counter.

One other consideration is how clear your sharpener is: in the event you’re sharpening in your storage, you then may not sweat the metal filings that sprinkle out of some sharpeners, just like the Work Sharp or the Presto sharpeners. In a kitchen setting, cleanliness is a should, and Chef’s Alternative Trizor and the $25 AnySharp Professional sharpener had been the cleanest. That mentioned, all of the above suggestions required minimal cleanup, if any in any respect.

Lastly, sound is a priority for some — and a few of these gadgets are considerably louder than others. The Chef’s Alternative Trizor is barely quieter than the Presto sharpeners, however none had been silent. If you’d like a quiet possibility, non-electric sharpeners might be your finest guess.

Out of all of the testing, the one gadget that appeared to haven’t any upside was the $eight Kadell three Levels Sharpener, which wasn’t as reasonably priced because the KitchenIQ sharpener and in addition carried out worse than every other sharpening tool I examined. Moreover that one, it appears just about any knife sharpener is best than no knife sharpener. So spend money on the excessive finish or decide up a $6 tool. Both approach, meals prep will get a lot simpler if you do.
