I've never thought of it in terms of how I describe myself to the world since, like most of us I imagine, I don't announce my grooming habits to the world as a matter of course, when I've spoken of others who shave with straights, I've just called them "straight shavers". For example, advising a newbie to find another local straight shaver to help him on his way.

Interested to see what others come up with. Hopefully there's something a whole lot better than my lame phrase.
