I've just had my second shave with my Blackland Sabre using the L2 and L1 baseplates with a GEM PTFE blade. The second shave was just as smooth and nice as the first shave. No nicks, no cuts, no irritation. So, here's my question. How many shaves can I expect to get from a blade? To give a baseline I get about four to five shaves for a Dorco Prime DE blade before my pick ups become more trouble than they are worth to keep using the blade. I also have the plane Jane GEM SS, Gem Blue Star, Pal, and Pace/Dorco SE GEM style blades waiting for trial. Will these blades give the same longevity as the GEM PTFE?
