You won’t need this feature when making knives, so don’t prioritize it thinking that you’ll be missing out without it. The purpose-built machines that are specifically made for knife making don’t have this feature because it’s not necessary. Buyers that need to grind through lots of material, use their machine very often, or have large and heavy-duty projects, should opt for a strong motor with high horsepower. A high-powered motor is the best option for many professional knife makers as the motor won’t bog down under tough materials and will last longer. Although any belt grinder for knife making will have the same basic function, each model can vary a lot in performance. They also may look different and can be modified to fit different projects.

The major downfall of the 1x30 is that the belt isn't wide enough to flatten off material effectively, which is a big job in any knife shop. Some of the more expensive models include a 6" disc sander on the side, which can help with this though. The 30” long belt doesn’t provide you with much abrasive surface area either meaning you’ll have to change belts more and the motor doesn’t have the most power in the world.

The performance of 1×42 belt grinders is comparable to that of 1×30 grinders. The grinding surface area is slightly larger, and the machines are more reasonably priced.
