Electric Kitchen Knife Sharpener Buying Guide

Choosing the right sharpener for the kitchen knife primarily depends on your needs and preferences.

There are a host of options with a variety of features at your disposal. But not all of them you’ll need.

So, finding the perfect one can be stressful.  There are various aspects to consider before jumping in.

To avoid all the confusion associated with buying a knife sharpener, here are some of the factors that you should take into consideration.


Some models are designed for sharpening fine edge blade and regular kitchen knives. Whereas some are more versatile to put a sharp edge on the curved blade or non-kitchen knives. Some premium models are also available that can sharpen all kinds of knives and other cutting edge tools.

So, before selecting a model, consider your needs and the compatibility of the sharpener with the blades.

Angle Guides: Fixed vs. Customizable

To acquire a sharp edge, you need to keep the blade at a precise angle during the sharpening process. Moreover, the precise angle setting also determines how sharp you want your blade to be.

American or European style knives are better suited to a 20-degree angle. And the Asian-styles suit to 15-degree angles. So, make the right assessment of your knife collection before jumping in.

A kitchen knife sharpener may feature a fixed or automatic angle guide. A fixed angle guide is great if you are an expert, and you can figure out which angle to sharpen the knives. However, most models do that automatically to make the whole process simple.

Type of Sharpening Abrasive

This type of tool uses diamond-incorporated materials, Tungsten carbide, Sapphitite sharpening wheel, or abrasive belts to get the job done.

Although diamond abrasive is perfect for coarse grinding, it might be too aggressive for precision grinding. It might even damage the thin or delicate blade rather than sharpening it.

Sapphirite ones are less aggressive that diamond abrasive and still perform the job well.

Abrasive belts that are available in various grits offer you a lot of flexibility. It’s undoubtedly the best electric knife sharpener for a regular user or professional user who wants precise control over the sharpening process.

You can sharpen all types of blades no matter it is straight-edge or serrated. So, if you need to put a sharp edge on a wide variety of knives and cutting tools, go for a sharpener with abrasive belts.

Number of Sharpening Stages/ Slots

In terms of stages, a lot of these units offer multiple stages of sharpening. The number of stages determines how the blade will be sharpened and how complicated it is to operate.

Dual-stage units are simple to use. On the negatives, they don’t provide much precision. Two-stage sharpeners are good for home use.

Three-stage units offer more precise results than two-stage ones. They provide coarse sharpening, honing, and polishing. These models are better suited for professional use.
