Tips for Using a Belt Grinder

There are always some tips and tricks for specific jobs that make the job easier. So, let me tell you some tips that will help you to work with your belt grinder nicely and neatly. 

Heat-resistant gloves:

Get a pair of heat-resistant gloves for your knife-making and shaping sessions. After using the machine for a few moments, the machine starts to get scalding. So, to save your fingers from blisters and burning get heat-resistant gloves.

Use your full power:

Do not depend only on your hands while working with a grinder or sander. Use your whole body; maintain a healthy elbow posture while doing your job. It will help you to maintain stability while working with your grinder.

And don’t rely on just one hand while shaping and honing your knife. Use both hands to sharpen both sides of your knife for perfect finishing.

Keep water near you:

As the machine and blade both get hotter while working with them, you may need water more often to cool down the knife as well as the machine.

A Buyer’s Guide to the Best Belt Grinders for Making Knives:

Though some reputed brands sell top-quality belt grinders, you need to look for some features that turn a grinder into the best one.

So, let me give you a brief idea about what to look for in a belt grinder for buying it.

Motor power:

Belt grinders for forging blades come with 1 horsepower to 1/3 horsepower motors. The strength of the motor determines the workload that the machine can take.

Therefore, if you are planning to do some heavy-duty jobs regularly, you can choose a grinder with a robust motor. Otherwise, you can get a lightweight medium-duty machine for occasional crafting.

If you try to do massive works with a low­-powered machine, it may freeze or stop working. Even some accidents may happen while doing such things. So, choose the power of your motor very carefully.

Easy to maintain:

The machine creates a lot of dust and fragments while working with materials. Some grinders come with a dust bag to help you with collecting the rubbish. But there are a lot of grinders that come with the complicated cleaning process.

A machine with a complicated cleaning process will be messy. And if you don’t clean it appropriately, it will lose its efficiency in no time. So, it should get easy to maintain the machine. It will save you time and keep your machine running for a long time.

Size of the belt:

The size of the belt is essential for a grinder or sander. Medium to narrow belts are suitable for working with accuracy. While buying a grinder for knife making, always try to get a 2×72 belt grinder. This particular belt size is right for making knives as well as sanding.


The speed of the machine plays a crucial role in buying a grinder. With the one that has lower speed, it will take time to finish your work. But there are lesser chances for making mistakes. Low-speed grinders are best for beginners.

High-speed machines will work very fast and need an expert hand to control them. However, the belt of the high-speed machine wears out very quickly.

Considering all these, you should get a grinder with adjustable speed. It will make your knife-making sessions trouble-free.

Easy to assemble and use:

Who wants to waste their time in reading complicated manuals and painful using procedures? So, get a machine that can be used easily. 

There are also some grinders with complicated belts and disc-changing processes. Avoid these types of machines with a problematic procedure to save your time and energy.

Size of the sander:

Do not choose a massive disc sander that is difficult to install in your workspace. Otherwise, it will be a very troublesome process to adjust it every time you are working with it.

Dust collection system:

As I revealed before, you need to keep your machine clean as appropriately as possible. So, get a machine with an additional dust port or dust bag to have a cleaner surrounding and natural cleaning process.

Contact point of the machine:

The plate-like part of the grinder is the contact point of this machine. When you are forging a knife, this plate puts a stop to the knife from hanging in the side. 

If you are buying a grinder for forging blades, check out if the plate can tilt up to 45 degrees or not. If it can, it is ideal for making blades.
