I ground that particular knife on a 1'' 30'' Grizzly Belt Sander/disk sander, but actually purchased and received a KMG-PL with variable speed about 1.5 days ago, still haven't got it put together, and need to get a power cord, and some odds and ends. Don't have anywhere to put it, but like I said a shop is in the works in the near, near future. Money can't buy skill, but I think this will help me stay with the craft, I don't think I'm going to loose money on it, I think I'll enjoy it a lot, and that's worth it to me. I know you don't need one, but I had been putting money back for something kind of frivolous and not useful, so I decided to buy this instead, still trying to put it together, I'm not the sharpest tool in the shed when it comes to electronics especially motors, and whatnot. I was hesitant to post this seeing as a novice like myself isn't really worthy of such a fine tool. Some might cringe a little.
