I have been playing around lately with some synthetic edges and even some film edges, but decided to break this coti and razor out. I hadn't used this stone in quite some time so going in I told myself that if I didn't hit it just right I could always finish it on one of my Les Lats. Well no such remedial measures were needed as I got a superb edge. The HHT was crazy good. So good I went and got another hair just to confirm it and watch the hair silently fall. Shave will be this evening.
