The perfect sharpener I used whereas testing was the $150 Chef’s Alternative Trizor XV, a cumbersome system with three separate tracks for bringing boring 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 preserve your blade angled accurately, so danger of creating errors whereas sharpening a boring blade on the diamond abrasive sharpeners is fairly minimal. 

The outcomes of my testing have been spectacular. The sharp blade and clean 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 you probably have loads of counter house or do not thoughts storing it in a cupboard, the Trizor is the best-performing system round.

Should you’re much less interested by sustaining an ideal edge in your knife blade, and as a substitute need an reasonably priced, “good-enough” various, the $6 Kitchen IQ 2 Stage Knife Sharpener is perhaps for you. No, it will not absolutely resurrect an previous, boring blade, however this sharpener may also help sustain a greater edge than traditional with just some passes by means of the sharpening tracks every day.

The Kitchen IQ additionally contains two tracks: a rough sharpener for setting the sting, and a high quality 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 Phases sharpener, the Kitchen IQ stands out. 


To check our knife sharpeners, we acquired eight an identical chef’s knives and dulled them utilizing a Dremel. They nonetheless might minimize tomatoes and pineapples (our two testing fruits), however not cleanly; basically, we wished 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 certain all of them carried out about as poorly as we wished 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 means of “till sharp,” and I did so till the enhancements appeared negligible. Different sharpeners have 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 minimize with every fruit out of 10, noting my particular observations. The first objectives right here have been to see how sharp the sting grew to become and the way clean it was throughout its size: a pointy blade should not squash a tomato, and a clean blade should not tear its pores and skin. A pineapple would check the identical results in a better stress context — chopping by means of a strong fruit in a non-straight sample.

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

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 looking knife). Whereas the Chef’s Alternative sharpener is the perfect for chef’s knives, each the Presto Three Stage and Work Sharp gadgets supply a bit extra flexibility for various blades. Presto, for example, can alter 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 which will postpone informal cooks, however will probably attraction to DIY fans.


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

One other consideration is how clear your sharpener is: should you’re sharpening in your storage, you then 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 Alternative Trizor and the $25 AnySharp Professional sharpener have been the cleanest. That stated, all of the above suggestions required minimal cleanup, if any in any respect.

Out of all of the testing, the one system that appeared to haven’t any upside was the $eight Kadell three Phases Sharpener, which wasn’t as reasonably priced because the Kitchen IQ sharpener and likewise carried out worse than every other sharpening tool I examined.
