I saw this one hair removal kit, by Conair, that uses a round disk that feels a little like sand paper and supposedly it removes hair by exfoliating the skin and thinning out the hairs. I have a link..

I don't know how well this would work but it sounds a bit painful. I mean come on sandpaper? Or as they call them 'fine grain exfoliating pads', heh
