Just to clear everybody's mind, I would NEVER let her use one for that. I just thought it was funny that she would even ask even though she knew that her mom was talking about a single edge. I'm pretty sure she did it just to see how I would react. I politely declined to let her destroy even one of my project blades and suggested that her mom was not talking about my straights. As far as letting her use one on her legs, I can't even get her to switch to a DE.
Pretty sure eh? With women I would not bet on that. A lot of gals wouldn't ask. They would just take it and use it and a few days later you'd be starting a post asking how your razor got all chewed up just sitting in the box.
