Electric Knife Sharpener Buying Guide

When you set out to purchase the ideal, most high-quality electric knife sharpener, there are a number of factors and characteristics you should consider. To help ensure that you get just the right electric knife sharpener for your needs and preferences, below we have outlined and explained some of these characteristics.

The Size of the Sharpener

What size electric knife sharpener do you need? This depends on the number of features you want (or could live without) and the amount of storage and/or counter space you have in your kitchen. Electric knife sharpeners can range from very large, with a number of unique features ranging from sharpening to honing, to fairly small with just a few key features. The typical knife sharpener takes up about as much storage and counter space as a toaster or blender, but there are models both on the large and small side of typical.

Number of Knife Slots

You may have noticed that knife sharpeners can have between one to four knife slots. These extra slots are actually designed to do different tasks on the knife, and many are designed to help sharpen your knives at different angles.

There are electric knife sharpeners with sharpening and honing slots, grinding slots in which the material being used is very abrasive and meant to grind the blade; smoothing slots, in which the ground knife surface is smoothed into a fine, sharp edge; and polishing slots, which help fine-tune that edge from top to bottom.

Slots at different angles allow you to sharpen different types of knives, ranging from bread knives to meat cleavers, and do it in a way that best suits the blades on these types of knives. To get a better idea about the different types of knife sharpeners on the marketplace, we recommend you read as many reviews as possible until you find the type that is just right for your collection of knives.

Corded or Cordless?

Knife sharpeners come in a variety of types, but the two most common electric knife sharpeners are the corded and cordless varieties. As the name suggests, corded electric knife sharpeners have an electrical cord that plugs into a standard wall socket, guaranteeing continuous power to the machine.

These types of sharpeners tend to be much more powerful than their cordless counterparts, but make sure you buy one whose cord is long enough to stretch easily to the first open electric outlet. Cordless electric knife sharpeners are not as powerful, but they do add the benefit of convenience and portability.

Cordless electric knife sharpeners can be placed anywhere on your counter without regard for the nearest outlet; and they can even be used in places where no electricity is present whatsoever, provided they have first been charged up to full battery capacity.


Although no corded models (and few cordless models) of electric knife sharpeners are completely dishwasher safe, you will still want a unit that is easy to keep clean and care for. To gather this information, we again recommend you read some reviews from actual customers who have owned and used the electric knife sharpener you plan to purchase.


Finally, as with any electrical product, a warranty is a must when buying an electric knife sharpener. A longer warranty tends to demonstrate the utter and complete confidence a given manufacturer has in its product. On the flip side, a shorter warranty—or no warranty at all—may be a sign that this is an inferior product, one you should simply pass on.
