Best knife sharpeners for 2020: Chef’s Choice, AnySharp and more

I’ve used a lot of chef’s knives over time and are available to understand every of them for his or her distinctive really feel — the heavy-duty Wusthof (my first chef’s knife) is nice for cubing squash, whereas I really like my World knife for mincing veggies and herbs. However even a premium chef’s knife will boring over time, and $150 (not to mention far more expensive options) can really feel like a waste when your Wusthof cuts in addition to a $10 generic knife after solely a month or two. Enter the knife sharpener.

Knife sharpeners are far much less frequent within the common kitchen than many other tools, regardless of their worth. Some skilled cooks sharpen their knives every day, however even the informal prepare dinner will profit immensely from sharpening their knives as soon as a month.

The excellent news is knife sharpeners do not need to be enormous investments. Like some other kitchen software, what you set in is usually what you get out: A couple of dollars can get you measurable enhancements to your blade, and 20 instances that may hold your chef’s knife’s edge as sharp as new in perpetuity.

There are many instruments on the market for preserving knives sharp — we’re positive you are all accustomed to the sharpening stone and the sharpening rod — however we wished the knife sharpening course of to be just a little simpler than these explicit sharpening instruments. So we examined the heck out of some sharpeners to determine which of them will at all times lead to a pointy knife with out you having to fret concerning the sharpening angle or anything, and nonetheless get a razor sharp edge from a previously blunt knife. Listed below are our picks of one of the best knife sharpener on your chef’s knife, and we will replace it as we take a look at extra merchandise.

A observe, although: We’re speaking simply chef’s knives right here. A serrated knife might have a distinct type of sharpener.

One of the best sharpener I used whereas testing was the $125 Chef’s Selection Trizor XV, a cumbersome machine 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 easy methods. Plus, magnets on the sharpening tracks hold your blade angled accurately, so threat of constructing errors whereas sharpening a boring 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 machine 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 ($125 is greater than most individuals pay for a chef’s knife, not to mention the software that sharpens it) and its cumbersome profile. However if in case you have loads of counter area or do not thoughts storing it in a cupboard, the Trizor is the best-performing machine round.

For those who’re much less fascinated with sustaining an ideal edge in your knife blade, and as a substitute need an inexpensive, “good-enough” different, the $6 KitchenIQ 2 Stage Knife Sharpener may be for you. No, it will not absolutely resurrect an outdated, boring blade, however this sharpener may help sustain a greater edge than standard with only a few passes by means of the sharpening tracks every day.

The KitchenIQ additionally consists of 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 KitchenIQ stands out. 


To check our knife sharpeners, we acquired eight 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 sure 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 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, 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 targets right here had been to see how sharp the sting grew to become 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 strong fruit in a non-straight sample.

Which is one of the best knife sharpener for you?

A very powerful aspect of a knife sharpener is its capacity to sharpen an edge throughout the size of a blade. That mentioned, loads of different components may make different gadgets a greater match for you. Listed below are a few of these components:

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

Typically, sharpening a serrated blade particularly requires a serrated knife sharpener, however you continue to could need 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 one of the best for chef’s knives, each the Presto Three Stage and Work Sharp gadgets provide just a little extra flexibility for various blades. Presto, as an illustration, 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 doubtless attraction to DIY fans.


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

One other consideration is how clear your sharpener is: when you’re sharpening in your storage, then you definitely 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 Pro 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 Selection Trizor is barely quieter than the Presto sharpeners, however none had been silent. If you would like a quiet possibility, non-electric sharpeners will probably be your greatest guess.

Out of all of the testing, the one machine that appeared to haven’t any upside was the $8 Kadell 3 Stages Sharpener, which wasn’t as inexpensive because the KitchenIQ sharpener and likewise carried out worse than some other sharpening software I examined. Apart from that one, it appears just about any knife sharpener is best than no knife sharpener. So put money into the excessive finish or decide up a $6 software. Both manner, meals prep will get a lot simpler whenever you do.
