Dana, I get down to 1200 grit belt on my contact wheel and then go to a well-worn 1200 grit belt with grease. I then hand polish the blade with Norton 3/0, and then to 4/0 polishing paper, then I finish with the buffing wheel. My goal is to try to achieve mirror finish with least amount of buffing wheel use so that I don't buff out the sharp transition corners between the hollow ground surface and the flats. Regards, Mike O.
