Ok, great. So I don't need to run out and buy a bevel setter. I was only thinking about killing the edge because that was one of the requirements of the Janorton experiment. Although, somewhere Lynn said that starting at the 4K (or 800 for that matter) would effectively change the edge anyway. So, other than to removed chips and such, what would be the purpose of killing the edge on glass or the like? Some of the blades ised in Janorton were in good shape. By blade is in ok shape right now but just isn't shaving well anymore.
