Is it possible to get a decent one pass shave? I have a beard that grows every whick way and have very sensetive skin. After the first pass my skin is fine, but the shave is not so good. With each succesive pass I get more irritation and burn. I've been experimenting with different creams, soaps, and preshaves. Also with blades and the adjustment settings on my M15 Schick adjustable. Don't get me wrong. I can achieve a very good 3 pass shave, but it usually comes with some irritation and burn on my neck. Is the one pass shave possible or I'm I wishing for the moon? How should I try and achieve it?
