Among all the sharpeners we tested, the Chef’s Choice Trizor XV produced the sharpest and most consistent edges.

All other sharpeners could not match its quick and reliable performance. Even if you’ve never used a knife sharpener before, you can’t make a mistake due to the design.

Most importantly, the Trizor XV consistently restores dull knives to a razor-sharp edge, no matter how bad they are.

According to one reviewer, “This product is excellent. My old knives were very hard to cut anything with and had not been sharpened for over 15 years. Rather than throwing them away and buying a new set, I decided to try a knife sharpener. It was great!”

Things to Consider Before Buying Knife Sharpener

Sharpening Materials

You can find sharpeners in four different types on the market: carbides, steel, diamond flecks, and ceramic. A diamond fleck will provide a gentler sharpening process – since it causes less friction. Furthermore, the blades are less likely to be damaged.

Diamond flecks, on the other hand, are definitely more expensive than carbides. For you who cannot afford to pay over the odds, carbide is your best option.

The issue with steel and ceramic is that they aren’t effective sharpeners. As opposed to making blades sharper, their purpose is to improve the edge of the blade by honing.

Angle of sharpening

Knives generally come in two angles: the European style with a 20-degree tang and the Asian style with a 15-degree tang. No matter what sharpener you choose, it should be able to sharpen both these angles, at a minimum.

You may want to go for an adjustable knife sharpener, however, if you are unsure of your knife’s angle. You can adjust the angle to make the most of its utility, as its name suggests.


Contrary to popular belief, sharpeners can do more than just refine a blade. You can get a multi-stage sharpener – one that can both hone and sharpen simultaneously – if you can afford to spend a little more.

A three-stage sharpener, on the other hand, is a good option if you’re looking for a knife that offers precision grinding, coarse grinding, and polishing at the same time.

You could do well with a one-stage process if all you want is compactness – and a sharpener that is easy to use.

Multiple Slots

It is likely that not all knives are equally blunt, meaning some may require less grinding than those that have gone a little coarser.

To make the most of your sharpener, you need multiple slots. Each knife has a specific cutting tool provided by the different slots.
