So I just went for it, and I must say I'm pleased. I've got a little bit of burn, but it's relatively small and better than how I sometimes ended up with a safety razor. And best of all, no cuts! (Except for going over a pimple or something, but I don't count that.) I didn't get as close a shave everywhere as I hoped, especially down around the Adam's apple, but that's just because I was afraid of killing myself.
I didn't use any sort of pre- or post-shave treatments, just a hot shower and soap, but I think that would make it much more comfortable. Any suggestions? I've heard favorable things about using an alum block, maybe I'll pick one up somewhere...
