I tried a new blade (to me) tonite, and man it was wicked sharp. The funny thing was, it wasn't a Feather. It was one I've seen Leisure Guy write about: the Bolzano. It was only one shave and one blade, and it was in my most aggressive razor (which is also my favorite, the iKon Bulldog). But it blew by most of the others I've tried for sharpness. FWIW I have tried the Feathers, but that was months ago when I had much less experience. I'm going to try them again, but in the meantime I had traded off some sharpness looking for smoothness. As my technique has improved since then, I think I'll revisit some of these blades. Anyway, if sharp is your object, you might want to try Bolzano.
