When I first started DE shaving at 15 in 2009, I automatically dismissed all open comb safety razors as outdated & unnecessary. However, now that my facial hair has grown from peach fuzz to something that remotely looks like a beard 001_tt2 I am seriously considering open combs. Is there a big difference between open & closed combs? I figure the combs would, well...comb the hair which would make it easier for the blade to cut.
