A safety razor. The name is a little misleading because the first time I put it to my face, I quickly realized the fact that it was the most terrifying shaving instrument I've ever wielded. so naturally I voted for the next closest thing (sword)
Ditto. I hate electric shavers. My Dad gave me one when I first started shaving that must've been made in about 1953, and it had a hole in the foil, so it would tear chunks of skin off my face if I happened to touch that area of the shaver. I quickly developed a quite rational fear of the damn things.
I voted "straight razor" because I assume that's what a Gillete Mach 3 is? Although results suggest otherwise ... but FYI a blade is the old 'cut throat' single blade thing that barbers use.
