I'm one of those rare women who also uses a straight razor and it's the closest shave by far. However, I don't use shaving cream from a can. I just buy the cheapest stuff on the shelf and it works just fine on my legs.
My wife won't use my straight razor, she's afraid she'll strip her flesh of with it :1orglaugh
Shaving your legs with a straight razor? Now that's talent! I'd probably be in the same boat as your wife! :1orglaugh
