Knife Sharpener Buying Guide

Certainly, there are many ways to sharpen a knife. You can use a stone, a metal rod, a piece of leather, or a sophisticated motor-powered device. However, the quality of the obtained results mainly depends on the user’s expertise. But, it’s also true that choosing a good knife sharpener can make the sharpening process much faster and more efficient.

In this buying guide, you’ll find a list of tips to help you find the best knife sharpener for you. If it’s the first time you buy one, following these tips will help you be better prepared to make a better decision.

Type of Knife Sharpener

In general, a knife sharpener can be a manual knife sharpener, and an automatic knife sharpener, or an electric knife sharpener. However, from these two main groups are derived three main types:

  1. Whetstone
  2. Honing steel
  3. Electric sharpener

A whetstone is the most basic form of a knife sharpener. It’s basically a rectangular stone where the knife is slid several times to be sharpened. Whetstones can be natural or artificial. It’s a fact that artificial whetstones are much more efficient and reliable because they retain a uniform roughness all over their surface.

Usually, whetstones are immersed in water or coated with oil before each use. Doing this allows the blade to slide more easily over the surface. It also prevents the metal from getting too hot and warping.

On the other hand, honing steel is a metal bar covered with ceramic where the blade is slid in a top-down movement. They can also help preserve the sharpness of the blade. However, its main purpose is to straighten the blade.

Electric sharpeners are motor-powered devices that can sharpen a knife in a matter of seconds. They may use a belt or disc covered with an abrasive material like diamond dust, aluminum oxide or ceramic. Unlike manual knife sharpeners, electric sharpeners carve a new V-shaped cutting pattern on the metal after each use.


When it comes to knife sharpeners, it’s convenient to have different grit levels. Therefore, multi-stage knife sharpeners are the best of all. These devices allow you to choose the most appropriate grit depending on the wear level of the blade.

For example, 3-stage sharpeners have three different slots where the blade can receive different treatments. In the first slot, the blade receives coarse wear where major imperfections are removed. Then, on the second slot, the blade receives medium wear and a new V-shaped cutting pattern is carved on the surface.

Finally, on the third stage, the blade receives a smooth polish that restores the shine of the metal and removes any small imperfections.


Fortunately, most knife sharpeners have affordable prices. However, some electric models can be really expensive, exceeding the $100 limit. So, before choosing any model, you need to know your budget. If saving time is important to you, it’s recommended that you opt for an electric model. So, you’ll have to pay more.

On the other hand, if spending more than 15 minutes sharpening a knife isn’t a problem for you, opt for any manual model of your choice. They’re the cheapest ones and you can always order find one for less than $30.
