I smell a troll. FWIW, I simply build lather on my face but that's a personal preference, not a law. When I'm traveling (often by motorcycle) I pack light and a bowl for shaving wouldn't occur to me. YMMV
After thinking about your question, perhaps the blooger who shall remain unnamed has a prehensile tail?Larry C in Texas said:My name is Larry and I'm a shavegeek.
Concerning the unnamed blogger's article, if you make lather in your left hand, how do you use that hand to hold the razor to shave that side of your face without getting lather all over the place? I'm ambirazorous, so unless I can grow another hand, I'll continue to make lather in my $0.50 bowl from the thrift shop.
By the way, I prefer the term WIS - Wetshaving Idiot Savant, rather than shavegeek. This is not original - I borrowed (stole) this term from the watch forums, where it's Watch Idiot Savant.
YMMV.
