Every day with rare exception. I don't have any other shaving apparatus in the house except for an old Gillette DE, and to be honest, that thing is more trouble than my straights to prepare for a shave and then clean up afterwards ~ unscrew, insert blade, screw it back together again, and then removing the blade and rinsing/drying, etc. I shave every day for two reasons: I enjoy it and don't want to miss the opportunity, and I find the shave more comfortable with only one days growth. On the ocasion that I nick myself, I'm just shave a little more gingerly in that spot the next day. Two days and it's 100%. If I oversleep (rare) I only do a one-pass shave. ...............Jeff
