Knife designing extends back to prehistoric times when a good knife could differentiate between life and death. While knives aren’t as important today as they were many days ago, that doesn’t mean that knife making is gone. Knife making, as a hobby, has become so popular.

A machine will always make things easier while you have the art. Also, are you ready to grind your knives against rocks like in the prehistoric times? Well, in the twenty-first century, it doesn’t seem practical. If you are a serious hobbyist who wants to make more knives or is a newcomer looking for his first machine, you must have a top-notch knife grinder.

There are tons of knife grinder brands here, and choosing the right one can be difficult, especially for a beginner. However, now that you have found this reading, there is no need to look anymore.

Why Use a Belt Grinder for Knife Making?

Using a belt grinder is not a prerequisite for knife making. At the beginning of the iron age, people used to grind their metal knives with rocks manually. So, you can choose to grind your knife if you have all the time in the world and don’t bother being left with a primitive-looking weapon. 

A knife grinder makes chiseling, beveling, sharpening the blade, and making a breeze. Your work will be more symmetric, accurate, and time-saving. 

If you want to work with exotic or exquisite designs on your knives, then a grinder is necessary. Besides, other than knife making, sharpening household tools like a lawnmower and kitchen knives also need sharpening. A knife grinder will save you from purchasing the whole set of tools and knives by sharpening with the minimum effort. 

Are Grinder and Sander the Same?

Grinding and sanding are the different results of the same motion. Sanding is referred to as polishing material by light strokes. Usually, wood and similar materials need sanding for removing paint and polishing. 

On the other hand, grinding refers to removing a lot of material very fast from a metal piece. This motion helps to sharpen and chisel knives. Usually, all the knife grinders can be used as a sander as well. If you change the belt, speed, and hold the workpiece against the belt lightly, it will sand the knife instead of grinding. Besides, the sanding option helps to work with the knife handle while the grinding is a must for blade making.

Things to Consider Before Buying

Right Speed

Right power and the right speed of a knife grinder is a must thing you should know. It can affect the project process time. On the other hand, if you get one with more power, it can also be unable to give you much better ending results. So, you need to get the grinder with the right speed.


A knife grinder is powered through a motor. So, the motor should be powerful according to your project; otherwise, it will slow down your work.


Some knife sharpening grinders are made of metal materials or solid aluminum, which means they can last longer. Some of them are made up of cheap materials, which means they can probably break and can be useless in a little passage of time.

Belt Size

Which grinders have narrower belts can give you more control over small objects like knives. But if you are planning to work on larger objects, you better get off with a belt with features like a wider belt.

Ease of Use

A machine you are buying must be easier to operate and to maintain. So that means the more you use it, the faster you’ll be able to work. It should be easy to assemble too. As you can change belts easily whenever it is needed.
