The Best Electric Knife Sharpeners

Table of Contents

The easiest way to keep your knives in tip-top shape for better and safer handling is to use an electric knife sharpener. These handy devices plug into a socket and make quick work of grinding, honing and polishing all manner of knives, extending their life and keeping them functioning well. Electric knife sharpeners are usually designed to hone one type of blade over another, although there are others on the market that are more versatile. The e-sharpener you choose should depend solely on the material and the edge of the blade, as this will determine the sharpening method. And as you know, not all blades are shaped the same nor are they made from the same materials.

The most common blade material is stainless steel, or carbon stainless-steel. You can also buy blades that are high-carbon stainless steel and ceramic, which can be straight-edged, bevelled or serrated. Wide or thin, there are many different types of knives that you might need to sharpen quickly and easily while cooking.

Below, you will find a list of our recommendations for the best electric knife sharpeners, along with information on how they work and the tasks they perform.

Some people prefer to have ceramic-bladed knives for their superior sharpness, resistance to rust and their ability to stay sharp longer. That being said, it is those very features that make them susceptible to chipping and breaking; sharpening them is not an easy task and many knife sharpeners are not designed to do the job well.

Equipped with a powerful #600 grit diamond grinding wheel, the sharpener can remove ceramic chips up to 0.5mm deep, refreshing a dull ceramic blade back to a smooth medium/fine sharp edge.

What to Look for in an Electric Knife Sharpener

It’s important to choose an electric knife sharpener that is designed to work on the kind of knives you have. If all of your knives are straight-edged, then look for a device that works best with that kind of blade. If you have a mix of straight, flat blades, bevelled and serrated edges, then you will have to find a model that is made to adjust to each knife. You can ruin the blade of your knife if you use the wrong device to sharpen it.

Stages: There are usually two stages when it comes to getting your knives in shape: sharpening and honing. The sharpening process grinds away the dull material on the edge of the blade, while the honing stage polishes and resharpens the edge.

Because everyone’s knives are at different levels of dullness, you want to look for an electric knife sharpener that has multiple slots; some with coarse grit and others with a medium and fine grit.

Angle guides: The angle guide directs the blade into the sharpening wheel at the proper angle. This is really important because the wrong angle will result in you damaging the blade or not sharpening it correctly. The benefit of an electric knife sharpener over a manual one is that electric models include guide that make sure they are perfectly angled to hone the blade correctly.

Before choosing an electric knife sharpener, try to determine the sharpening angle of your knives to make sure it will enhance, and not harm, the blades.
