Still more or less a newbie here... Was wondering what the deal is with open comb razors? Do they provide a more aggressive shave? I am envisioning little rows of closer contact being made as some of you skin/whiskers squeeze through the open sections of the comb as opposed to the uniform stretching a straight bar provides. I come up with all sorts of theories with no real proof Just ask my girlfriend (I always say you state anything with enough authority and it can pass as truth. ) Other than my "theory", what's the thought behind the open comb set-up on some older razors and merkur open combs? Just curious. Thanks!
