I've been working on learning fan (tessen), but not in a soft style like kung fu or tai chi. I've done some reading and decided to use it in a harder way (I do karate), with more strikes, jabs and hard slashes--no smooth waving or throwing from hand to hand. I've read that fans were used in ancient Japan in places where other weapons were forbidden, and were also used by law enforcement either alone or in conjunction with a type of mace (name escapes me at the moment.) So far, I use just one fan, not two; I think I'm going to stick with that as it seems to me more logical for a practical weapon of self-defense. Not that I'm going to carry the thing around with me, but it makes my imaginary fighting (kata) seem more real to me.
