A corollary to this whole thread: Why do razor blade companies compete
against themselves with multiple kinds of razors? I can understand
having different levels of quality (Sensor, Sensor XL, etc), or having
different uses (for coarse hair, for sensitive skin, etc), but most
razor companies simply make multiple kinds of razors with little
explanation as to any kind of differences in them. Wouldn't it make
more sense to promote one kind of razor as better than the
competitor's brands?
