Autostrop A1 with a modified Gem stainless steel ptfe blade, shave 3.
Still the king of Autostrops for a close shave. Not only does it get me to a glass like BBS finish, it also takes an extra layer of skin off in the process if you aren't careful. There really isn't any Gem style razor I've used that comes close to this one for overall efficiency without being overly aggressive at the same time. It is deceptively mild.
