I say thanks to Sharpco and Grepper. Grepper and I kicked this can around for two years and it is amazing to me that you, Sharpco, have duplicated the problem precisely. I still say that Grepper deserves the Nobel prize for burr removal in discovering that the LOW was attached to and part of the edge apex. This was accomplished with a microscope and an exacto knife.
It's a mean critter this LOW. I actually failed to remove it with a wire wheel on a bench grinder. This, I believe, was due to the fact that the wires were unable to get beneath the LOW and lift it. Grepper did lift it with the exacto blade and very clearly so. We know that a scotch brite belt will remove it and we don't understand, necessarily, why. The key is to remove it without diminishing sharpness. If you do it correctly, you'll drop from 150 to 100 and incorrectly, you'll add 30-50 points to your score. I say you're better off, edge retention wise, removing and losing ground than leaving it on but that's supposition on my part.
This is the kind of stuff that makes sharpeners better at their craft so great job Sharpco!
