The very best sharpener I used whereas testing was the $150 Chef’s Selection Trizor XV, a cumbersome system 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 maintain your blade angled appropriately, so threat of constructing 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 system meant I might slice by means 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 do not thoughts storing it in a cupboard, the Trizor is the best-performing system round.

If you happen to’re much less enthusiastic about sustaining an ideal edge in your knife blade, and as an alternative need an inexpensive, “good-enough” various, the $6 Kitchen IQ 2 Stage Knife Sharpener may be for you. No, it will not absolutely resurrect an outdated, uninteresting blade, however this sharpener might help sustain a greater edge than typical with only a few passes by means of the sharpening tracks every day.

The Kitchen IQ additionally consists of two tracks: a rough sharpener for setting the sting, and a tremendous 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 Kitchen IQ stands out. 


To check our knife sharpeners, we acquired eight equivalent chef’s knives and dulled them utilizing a Dremel. They nonetheless might lower 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 urged passing the blade by means 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, taking a look at 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 lower with every fruit out of 10, noting my particular observations. The first targets right here had been to see how sharp the sting turned and the way easy it was throughout its size: a pointy blade should not squash a tomato, and a easy blade should not tear its pores and skin. A pineapple would take a look at the identical results in a better stress context — chopping by means of a sturdy fruit in a non-straight sample.

Which is the most effective knife sharpener for you?

Crucial aspect of a knife sharpener is its means to sharpen an edge throughout the size of a blade. That stated, loads of different elements may make different units a greater match for you. Listed here are a few of these elements:

  • Capacity to sharpen several types of knives
  • Cleanliness
  • Sound

Typically, sharpening a serrated blade particularly requires a serrated knife sharpener, however you continue to could wish to sharpen straight paring knives, boning knives, a fillet knife, cleavers or utility blades (or perhaps a pocket knife or searching knife). Whereas the Chef’s Selection sharpener is the most effective for chef’s knives, each the Presto Three Stage and Work Sharp units provide a little bit extra flexibility for various blades. Presto, for example, can modify its slots to information completely different blades extra successfully. Work Sharp makes use of attachments and belts of various coarseness for kitchen knives, pocket knives or scissors — a modular strategy that will postpone informal cooks, however will seemingly attraction to DIY fanatics.


Regardless of truthful outcomes, the Work Sharp appears rather more at residence in a storage than on a kitchen counter.

One other consideration is how clear your sharpener is: for those who’re sharpening in your storage, then you definately won’t 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 Selection Trizor and the $25 AnySharp Professional sharpener had been the cleanest. That stated, 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 units are considerably louder than others. The Chef’s Selection Trizor is barely quieter than the Presto sharpeners, however none had been silent. If you need a quiet possibility, non-electric sharpeners will likely be your greatest guess.

Out of all of the testing, the one system that appeared to haven’t any upside was the $eight Kadell three Levels Sharpener, which wasn’t as inexpensive because the Kitchen IQ sharpener and likewise carried out worse than every other sharpening tool I examined. In addition to 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 means, meals prep will get a lot simpler whenever you do.
