3 belts? I only used two <img src="/ubbthreads/images/graemlins/smile.gif" alt="" /> Whenever using grinding equipment on your knives use SHARP belts and light pressure. Dunk the blade often and do not wear gloves as they will mask heat build up. I worked slow with brand new belts and the blade wasn't allowed to heat up. 1 pass on the belt then dunk. Takes longer but it leaves the heat treat intact. No sense rushing and at best ending up with a cool paperweight.

Life is a grindstone. Whether it grinds you down or polishes you, depends on what you're made of
