Wow...good info guys thanks for sharing that. It'll come in handy having had this discussed here. I'm still having some trouble with this blade I'm working on though, even after working the toe half on the 1K to even out the bevel into a single full length bevel I'm still not getting the whole thing sharp yet. The heel half still cuts hair nicely (after a couple of pyramids) but the toe half just runs right over the hair without doing anything at all. I can't see any signs of a bad bevel, but I lack a microscope and all I have for magnification purposes is a magnifying glass. Are there any suggestions for what I can do to try working the kinks out further? Like should I go through a couple of the aggressive pyramids maybe three sets to see if things even out?
