How to Choice Best 2×72 Belt Grinder for Knife Making

To find the best 2×72 belt grinder for knife making, follow the guides given below.


Grits are the most critical thing that determines the finish sandpaper belt provides. They can be divided into more than three categories depending on the number of grits.

One thing to remember here is the more grits a sanding belt has, the more miniature course it will be. Their different categories are given below.


Coarse sandpaper belts are the ones that have the least number of grits on them. This number can be around 60 grits, but it does not exceed that. When used, they usually scratch the surface of the material.


The medium sandpaper belts are more delicate than the coarse ones. They usually come with almost 80 to 120 grits. The finish they provide is a bit smoother than the coarse ones. They are used for general purposes.

Fine and extra-fine:

Fine and extra-fine sandpaper belts are generally used for roughing up the surfaces. They usually have grit numbers that range between 180 and 320.


If you want to provide your materials with a shiny and glassy look, you can use the super fine sanding belts. Anything higher than 320 grits is considered to be superfine.

Now when how many types of sanding belts there are, you can make a better choice for yourself. The best one for grinding the knives is a coarse one.

Since it has very little grit, it will provide the highest amount of friction. But it would be best if you kept a variety in your hand to use at the different stages of the knife-making.

Back of the belt

People always say that there are two sides to a story, and that’s true, but what is also true is that there are two sides to a sanding belt.

One side determines the performance of the belt, and the other side determines its durability. So it’s essential to check the durability of the belt’s backcloth to ensure longevity and performance.


There are so many ways to grind a knife, and if your process involves wet sanding, then you should buy a sanding belt that is waterproof. Waterproof sanding belts are not very rare and are built specifically to withstand the process.

Anti-static technology

There is nothing worse than a clogged sanding belt during work. It also reduces the life of the belt which adds to the cost of production.

Since they wear off quickly, they need to be changed after a while, killing a lot of productive time. Therefore, always make sure that you buy a sanding belt that uses anti-static technology to keep the belt clean.

Joint of the belt

The last thing you may check while buying the best 2×72 belt grinder made for knife making is the JointJoint, where two ends of the belt meet each other.

If the JointJoint is not uneven, it will make that thumping sound every time the joint passes under the knife. That’s why you should always make sure that the belt is nice and even throughout.

Frequently Asked Questions

What’s the difference between a normal and an anti-static sanding belt?

If you look at an anti-static and a traditional knife grinder belt to make the best budget-affordable kitchen knife, you will not notice any difference between them at all.

And there is no difference in appearance at all. It provides the same kind of grinding if the belts have the same grits. But traditional belts get clogged, but anti-static ones don’t.

The reason behind the cogging of traditional belts is that they get electrostatically charged. And these belts are which they are unable to send to the ground, and as a result, they pull the dust towards them and get clogged.

On the other hand, the anti-static ones can conduct the charges and pass them to the ground. But to take advantage of an anti-static belt, your motor should have a ground connection.

Which one is better: a fine sanding belt or a coarse sanding belt for grinding knives?

As stated earlier in the buyer’s guide, a fine sanding belt is best for scratching the surface. But a coarse sanding belt is the one you should use for grinding a knife because it will provide you with the maximum amount of friction, and it will crush the knife faster than the more delicate sanding belt.

Will the grinder spark if I use the belt with metal?

Absolutely yes, when you are working with metals, you can expect some sparks. Most sandpaper belts use aluminum oxide, which, when rubber feet onto the metal, creates a few sparks, so always be careful when working with knives because sparks start a fire.

What kinds of materials can be used with these belts?

You can use these sanding belts for materials like aluminum, wood, non-ferrous metals, fiberglass, and plastics, including resins. So don’t worry when you have to use it for something other than just metal.


Remember, the most important thing you will use during the knife-making process is the sanding belt you use for grinding a knife.
