Can you teach yourself how to fight with weapons? Like kendo or something, I've studied boxing for a year, traditional for most of it, and a little bit of nunchaku.

Yes, I am practicing sparring, mixed martial arts and nunchucks, with more than six years of experience. Fighting is about practicality and good use, and the moves don't need to be varied. I suggest you learn Qi Mei stick. Just a few moves to sweep the army, raise the fire to burn the sky, Erlang to carry the mountain, pluck the grass to find the snake---it will be enough for you to deal with four or five people, but the foundation must be solid! Come on, remember one thing, one day do not practice ten days empty, ten days do not practice a hundred days pine.
