It features two spring-loaded sharpening wheels whereby one is coarse and the other one fine.

Despite electric knife sharpeners being convenient and easy to use, you still need to take the necessary precautions to avoid simple accidents.

Electric Knife Sharpeners Buying Guide

Factors To Consider

As we noted earlier, the average consumer is likely going to encounter a few problems when confronted with the decision to buy an electric knife sharpener. This would happen because there are way too many brands of electric knife sharpeners on the market. It is, therefore, important to put some factors into considerations into account.

These factors are basically the guiding aspects that will help you decide on the best model of an electric knife sharpener to buy. This section focuses on highlighting these factors and if you are just about to buy an electric knife sharpener, this section will be quite helpful. Here are the factors to consider when buying an electric knife sharpener.

The number of blade grooves

The number of slots or blade grooves is an indication of the sharpening system that the sharpener uses. Two stage sharpeners are the most common and preferred electric knife sharpeners. This is because they utilize the best electric knife sharper system whereby the blade is taken through two stages of sharpening processes. The first stage is where the blade is ground against a flexible abrasive surface to get rid of the knife’s dullness.

The second stage is where the blade is smoothened to give it a razor-sharp edge. The number of slots should help you decide on the knife sharpener to buy. The best electric knife blade is one that comes with multiple blade slots. This is because it allows you to achieve a smoother edge through the honing stage of sharpening. Also, a multi step electric knife is preferred because it supports a wide variety of knives.

The more the number of slots in an electric knife sharpener, the more the knives it can sharpen and the higher the quality of the sharpened knife. It is worth noting that some knives cannot achieve the best sharpening quality unless you position them at a particular sharpening angle. Multi step electric knives offer the functionality to select the appropriate angle before the sharpening stages. Others will have sharpening slots with specified types of knives.

The type of Knife

The type of knives you have in your kitchen should be one of the most deterministic factors to consider when buying an electric chef knife sharpener. This is because a significant number of these electric knife sharpeners are specific to a certain model of knife. For instance, you will find a certain knife sharpener that is only meant for Asian knives.

Another one would be specifically designed for European knives. You should also consider whether the knife sharpener supports double edge, single edge, serrated blades or thick bladed knives.

The amount of worktop space in your kitchen

Although the typical electric chef knife sharpener assumes a small form factor, it is always a good practice to consider the amount of worktop room that you have. Pick a sharpener that will not use up too much of the kitchen worktop. However, it is important to remember that smaller electric knife sharpeners do not have most of the features and functionalities that you may desire.

Therefore, you should also remember that when it comes to size, there are trade-offs involved. In short, if your kitchen worktop is small, you should not buy a knife sharpener that is too big as this would compromise your space as well as the functionality of the sharpener. Depending on your need for extra features in a knife sharpener, the electric knife sharpener that you buy should correspond to the size of your kitchen

The design and features of the knife sharpener

A large number of electric knife sharpeners on the market have a lot of differences especially when it comes to design and features. Some brands have decided to completely differentiate themselves from the rest by incorporating sophisticated and innovative functions into their electric knife sharpeners. For instance, you are going to find an electric knife sharpener that is combined with a can opener, a bottle opener, a screwdriver sharpener and a groove for scissors.

You are also going to find another brand with additional safety features such as non-slip feet with grip to enhance its stability on the kitchen’s worktop. Others will have design that automatically retract the cord into a cord repository. Choose an electric knife sharpener that is equipped with the features that you are looking for.

Ease of Use

Most electric knife sharpeners have a learning curve involved before you can comfortably operate and carry out your knife sharpening tasks. However, there are those whose learning curve is bigger than others. Always buy one whose ease of use is standardized to accommodate even the slowest of learners. You can identify such a sharpener by looking at the user manual.


The cost of an electric knife sharpener is an important consideration that you should make before buying one.
