How To Choose The Right Electric Knife Sharpener

To help you choose the model that best suits your kitchen needs, we have compiled the main features to consider before purchasing.

Angle Guide

Let’s start with a very important concept that is the sharpening angle. In a nutshell, the knife you are about to choose has a specific angle with which the sharp side of the blade was made.

Even experts in knife sharpening still need a device with an angular guide to reach the angle just mentioned. The guide also aims to make the use much simpler, more accurate and faster. That being said, we recommend choosing a product that has a guide on board.

Abrasive Material

The abrasive component of each electric knife sharpener is essential for perfect sharpening. The components used in the manufacture of the abrasive material affect the quality of the sharpening.

The materials usually used are titanium, tungsten carbide, ceramic, and diamond. Of these, the diamond abrasives do not overheat during sharpening, preventing the knives from being damaged during processing and allowing for a sharper and more durable blade.


Keep in mind what type of knife you will use with the model you are about to buy.

Are they knives with a straight blade or are they serrated? What material are blades made of? Will you use the sharpener also for scissors or other objects that need a sharp blade?

It is useful to ask yourself these questions in order to choose the most suitable sharpener. Nowadays there are very versatile models that can handle most of the models you have in the kitchen, both as regards the type of blade and the material.

Portability And Dimensions

As an essential part of an electric sharpener is the motor and the metal parts present

inside, take a look at the weight of the model you are analyzing. Also keeping in mind if you will position it permanently on a workbench or if you will sometimes move it as needed.

In this regard, dimensions also play an important role. Always try to stay in the middle, choose a model that is not too large to compromise portability, nor too small to affect functionality.


Since we are talking about rotating parts and sharp knives, do not forget the safety in use that the device design must guarantee. 

Take a look at the presence of rubber feet or parts that stabilize the sharpener and in models with a handle, check that it is ergonomic and provides a firm grip.

Ease In Cleaning

Like most small kitchen appliances, at the end of the use, it comes at the time of cleaning. Check if the design of the model you are examining is composed of removable parts that facilitate cleaning. 

Reaching the most uncomfortable parts to clean the small metal residues left around after a perfect sharpening can sometimes become a nightmare.

Number Of Slots

The series of two, three or four slots that are usually found on most electric sharpeners are dedicated to the different stages of the sharpening process. The number of phases can make the use more or less simple, it influences the size of the sharpener and is directly linked to the precision and quality of the final result. 

The operations of smoothing, grinding and polishing can be divided into different slots or for simplicity they can be merged into a smaller number of slots. Depending on the time and experience you have to devote to sharpening, always have a look at how many slots are present.
