Features to Consider Before Buying

Before you make your final decision, there are certain factors to consider in order to find the perfect grinder that will suit your needs.


Power is a very important requirement for choosing a sander. You want to choose a tool that has enough power to tackle the job you have at hand. The most common challenge people face is buying a sander only to discover that it can’t handle the heavy jobs they want to do.

If you buy a grinder that provides inadequate power for what you want to accomplish, the tool’s motor will most likely bog down every now and then.

So, make sure you consider the tool’s power. And also make sure it’s something that can really serve you.


In addition to power, you should also consider the speed and size of the tool you’re buying. You don’t want a grinder that is too heavy, or else you may not be able to go for long hours without developing hand fatigue.

In the same manner, you want a tool that offers the correct speed for your task (not too high or too low). Ideally, you want to go for a sander with variable speed settings, as this offers you more control.

Dust Collection

When using any power tool that removes materials, you should always think about how it takes care of dust produced from the job.

Choosing a sander or grinder that has a dust collector will reduce the amount of dust on the workspace, allowing you to work with more freedom.

It also reduces the amount of mess you have to take care of when you’re done working.

Ease of Use

You want to get a tool that is simple to operate. This is very important for you as a beginner.
The best rule is to stay away from sophisticated grinders that require users to be a little more technical. Or else you would spend hours trying to do something that would have taken you a few minutes if you were using a simpler grinder.

Such models are better suited for more experienced users. Stick with something that is simple and easy to use.

Final Words

By now, you should have an idea of what it takes to get a good grinder for knife making. As long as you adhere to the criteria we discussed above, you shouldn’t have any problem.

Make sure you take safety seriously while using any grinder or sander. Use the right safety gear to protect yourself and your work.

Also, make sure you go for a unit that will not require you to make huge adjustments. This is really important when you’re just starting out.

With our list, you should be able to get the best knife grinder for beginners that meets your requirements.
