I think I could easily kill myself shaving with a safety razor. Possibly this is because I do it too hard, with too dull or too sharp a razor, or am just generally unskilled. I've got some pretty impressive accidental scars...

When I started shaving my legs regularly (to pass at work) I deliberately went out and got one of those silly pretentious Venus razors, in the hopes that it would make it more pleasant and less full of fail. Which helped somewhat, although not entirely.
