on like, the second night i went to my dojo, i saw a green belt doing knife deffense. but check this; he was being taught to use the obi to deflect the weapon and stuff. this looked really cool, sort of reminded me of the rope javalin. anyways, do any of you guys learn this? what kind of stuff can you do with a obi? can it be used just to deflect, or can you do chokes, hand locks (these two looked obvious) with them. what about the robe javalin i mentioned, could you use it as a kind of wiping weapon? to actually strike the opponet?

One of my favourite "street weapons" is a rolled up copy of the "Economist! You should learn to improvise.

I donno if my school learns it, but I know Hapkido and a few other arts do. That would be sweet to learn something like that. Dang! My next art WILL be Hapkido!

what style does rope javalin i wanna learn that.

I know that you can strangle with an obi because we do that at my dojo.

And remember any defense you learn with your obi practice doing with the belt you normally wear with your everyday pants.
