What info is there on the blades I got in the other day from Buy Individual Razor Blades for Double Edge, Single Edge and Shavettes ? In with some Feather Soft Guard blades for my SS Feather I got a small sample of 2 blades of Kamisori blades. I used one the other night and it is a nice clean shaving blade. Fairly smooth, but information about this blade is rather elusive.
