Whether you are a professional woodworker or a newbie DIYer, choosing the right grinder for your knife requires a bit of diligence and thorough research. It is certainly not easy, but with these pointers, you can make your search much easier.

Here are a few aspects that you should consider:

Ease of Use

When buying any workshop tool or machine, always consider its ease of use. You obviously do not want to acquire a sander that will get your hands full. A good sander should be very easy to operate, for increased efficiency and productivity.

Tracking Mechanism

The tracking adjustment mechanism is another important consideration. It not only determines the efficiency of the grinder but also has a bearing on the quality of the results. The tracking mechanism should be simple and very easy to use for maximum control.

Belt Size

Belt sanders for knife-making are often classified according to their belt sizes. The sanding machine that you choose should accommodate a variety of belt sizes for optimum results. The most common size used by professional knife-makers is 2 inches by 72 inches. For beginners, a belt size of 1 by 30 inches is ideal for most knife-making projects.

Motor Power

The motor power, usually defined in HP (horsepower), will determine the performance of the machine. Typically, budget-friendly sanders have a motor power ranging from 1/3HP to 1/2HP. Nevertheless, always go for a more powerful motor if your job revolves around tackling tough projects.

Noise Level

Power tools often tend to be noisy. However, this does not mean that you should opt for any noisy sander out there. Shop around for a tool that releases low noise levels to give you an easy time when working in noise-sensitive areas.


Different machines offer different speeds ranging from single to variable speeds. Beginners should opt for variable rate machines as they offer the privilege of setting your desired speed.

Dust Collection

Working in a dirty environment is not only a safety hazard but also a health risk. For this reason, you should consider buying a sander that comes with dust collection ports for easy cleanup.


Belt sanders for knife making are often classified as long-term investments. For this reason, you should go for a tool that is durable and can withstand a harsh work environment. All-metal sanders are considered more durable than plastic versions. On the flip-side, sanders made using plastic materials and lighter metal are more portable.


The price of a good sanding machine all depends on the brand and the features involved. While it is advisable that you stick to your budget, you should always opt for a machine that provides good value for the money without compromising on your needs.


1. What should I look for in a knife-making belt sander?

Besides all the factors above, you must look for a grinder that is versatile, portable, and reliable. For enhanced efficiency, the sander must come with numerous auxiliary features that are easy to use.

2. Can I use customized belts with my sander?

Although not recommended, you may use customized belts for various projects. Some knife-making projects require the use of customized belts to deliver quality results. However, these customized belts are not readily available. You must place an order with a manufacturer to have it designed for your machine. You must also gather enough knowledge on how to measure your belt.

3. What should I do if my belt sander malfunctions?

Firstly, switch off the machine and disconnect from the power outlet before doing anything else. Check the sander for any damaged parts or a broken belt and make the necessary replacements. For any technical issues, always contact your service center or enlist a professional technician.

4. What is the purpose of a dust collection port?

Just like any other metalworking project, knife-making always involves a lot of dust and metal contaminants. The presence of these elements in your workshop can pose a health risk or even lead to dangerous thermal events such as fires. The dust collection port allows you to connect a hose from the sander to your vacuum cleaner for easy cleanups.
