Step 05

This is the last step on which you have to focus on keeping it cool. It is a vital part of sharpening a knife. You can do this step by dropping it inside the water. Or touch the motor housing with a bare hand every 20 minutes.

Next, insert it into the leather strip and link it to the honing compound. It is done at the same process as you have sharpened the knife. Most importantly, don’t skip these steps because they will help get the sharpest blade after a few strokes.
