My fiance was watching me shave the other day and she started playing around with the lather. She now claims she can make better lather than me (after one try!) but I would like to believe this is not true. Later when she took a shower she asked if I would try on one of her legs. I think the answer is obvious to anyone here, but of course I did. Even cooler was that she did her left leg after I did the right.

Verdict: there's certainly more surface area on the human leg than there is on a face, but other than that it is far easier. (YesSheDoes has already stated this, but she's presumably had practice on her legs for years now with a non-straight, I didn't know how much that helps.) It also takes a hell of a lot more lather! The fact that it is finer and sparser means you can go against the grain straight off without irritation or nicks. Still takes a while though.
