It's clear that shaving does not really advance significantly through the technology of its instruments. If a Schick Injector gave a good shave in the 1930s, and had given me good shaves for most of my adult life (I'm 65), the only reason that a "new razor" appears on the market is to increase the profits of the blade manufacturers. Why make a perfectly usable blade for pennies, when you can make a bloated multi-edge one and peddle it for dollars? Ah, the wonders of a capitalist economy!I could be wrong, but I'd imagine that many here on SBGs have never even thought that "old style" razors work(ed) just fine. If I were a truly BOLD Sly Guy, I'd learn how to use a straight razor, buy a strop, a brush, and a bowl of soap.
