Best Belt Sanders for Knife Making: Top Reviews of 2018

Using a belt sander to make your knives gives you an advantage since you are creating a convex edge and not a concave edge, keeping the blade sharp for a longer time. Using traditional knife makers reduces the structural integrity of the knife as more and more metal is shaved out of it. Therefore, using belt sanders to make your knives is a win-win situation since it allows you to maintain the structural integrity of the knives and at the same time keep the blade sharp for a long time.

What kind of belt sanders do you choose?

Before you go rushing off to get a belt sander, it is important to know about a few things that will help you determine which knife sander caters best to your needs.

1. Size: For a sander, the size criteria applies to two things- the size of the knife sander itself and the size of the belt. The size of the sander needs to be big enough to comfortably work on, and small enough to be easily installed on your workbench. 

The size of the belt also makes a difference- the best belt dimensions to make knives are 2 inches by 72 inches. This is because a larger belt gives you better grinding and sharpening when you are shaping the knife, and gives you more surface area, therefore lasting longer due to less wear and tear.

2. Motor: The motor is one of the main components of the knife sander. It is how you decide the power of your sander when it is in use. Usually smaller sanders have a motor that runs on ⅓ horsepower. Larger sanders run on a motor of 1 horsepower.  Bigger motors allow your sander to be more versatile, making it easier for you to grind and shape your knives. But smaller motors also work very well for compact spaces, giving reasonable speeds.

3. Contact point: The contact point is a plate-like structure that is a part of the knife sander. When you use a contact point the knife no longer hangs off from the side when you are making it. A few knife sanders have a large contact point while a few others have a smaller one. Unfortunately you cannot change the plate, but you can attach a new one on top of the existing one.

The plate should also be able to tilt at forty five degrees or more, to help with sharpening of knives. If the plate is unable to tilt, the sander will not be able to sharpen knives.

4. Speed: The speed of the knife sander is also essential for making the best knives. When the speed is too slow, the time required to complete a knife will be more, and when the speed is too high, the belt wears out too soon. Therefore the speed of the belt (and by extension, the motor) should be atleast 1725 rpm.

Here are a few useful tips when you start using belt sanders:

  • Put on a pair of heat resistant gloves
  • Always keep some water near you for the blade to cool down
  • When maneuvering, keep your elbows locked and use your body instead of your hands or fingers
  • Keep switching the knife around the plate
  • Use both hands to achieve an even sharpness on both sides
