Weapons

Today I got an email advising me that I need to get together with my instructors and decide on a weapon for weapons training. This will be cool! I'm excited about that. I have a Bo already, but learning more is going to be a great opportunity. I don't know if I want to continue with the bo or if I want to try my hand with kamas or with sais. I have a cheap pair of kamas, plus I 'inherited' some kamas from a girl I used to train with at the old dojang, which are wooden. I'm not sure I want to learn those or try something new.

That makes me wonder...just how many different weapons ARE there in martial arts???
