I've had the Norton stones for a long time, but I just got a series of Glass Shaptons from a friend for dirt cheap. I really want to like these stones because they need so much less lapping and it's a cool system. However, the stones I am using are incredibly slow in comparison to the Nortons. I've spent about 3 times the amount of time trying to set a bevel with the Shapton on identical razors than I do with the Norton. Looking at the grit comparison table they are about even in level. I searched for comments about the issue and I mostly just came up with threads from newbies asking which to buy. Has anyone else had the same issue? Am I just insane? Well, I know I'm insane, but is this issue unique to me? From what I have read people consider the Glass Shaptons a fast stone...
