How to Sharpen Your Knife Using a Belt Sander

Step 1: Bring the essentials

For sharpening your knife using a belt sander, you will need a few tools. Make sure that you have gathered everything. For the tools, follow the checklist:

  • Belt sander
  • Leather strop
  • Dull blade
  • Medium-grit belt
  • Honing compound

Step 2: Get your sander prepared

Well, now you should start with your medium-grit belt. You need to load it first into the sander. After that, choose the spinning direction of your sander. If you are determined about using the sander horizontally, then it will be the best as it will spin away from you. Again, the sander will spin towards your position if the sander vertically stands.

However, while loading the sander, make sure that the belt is not too tight. Because a tight belt is good enough to destroy your blade. You should not make the belt too loose too. It will be fine if you are able to push the belt a bit and also there is a little tension.

Step 3: Shart sharpening

You are in the main step of your job. In this step, you need to hold your knife and glide it gently across your spinning sander. Also, don’t forget to provide a bit of tilt on the knife to ensure that the sander is hitting your knife slope. You should stroke it repeatedly. Once you are satisfied, you can move to the opposite side.

While doing this process, make sure that you are tightly holding your blade using both hands. Keep in mind that the sander eats metal rapidly. In this process, keep one hand on the tilt and hold the blade tip using another hand. Thus, you will be able to have the most control.

Also, while running the blade across your sander, you should push the blade slightly. Pushing your blade in a too-hard manner can destroy your blade. You should push the blade to get a bit of bend on the belt. Thus, you will get your knife sharp. Remember that the belt sander will sharpen your knife very fast. You will be surprised to see the appearance of the edge.

Step 4: Cool the knife

Well, you have completed most of your work. Now, you need to get the knife cool. Sharpening your knife using a belt sander can overheat the knife. If the amount of heat is excessive, then there is a possibility of damaging the knife.

So, sinking your knife in water after a few strokes is always a good idea. It will make your knife ready for sharpening again. Without it, it will help to increase the durability of your knife.

Step 5: Honing

You are in the last step. Once you are done with sharpening, you are supposed to find a burr on the blade. For removing this, you will have to hone the knife.

So, you need to take off the medium-grit belt and place the leather strop. Then, chalk it up with the help of your honing compound and start honing. You should hone the knife in the same way as you have sharpened your knife. 

As a result of honing, you will get the most possible sharpness. However, after going through a few strokes, you will find that there is no burr in your knife, and you are done with sharpening your knife.
