I watched for a few minutes until I saw you twiriling the sword around your head and body, then I stopped, thinking, "this chick's gonna hurt herself." That's one of the last things you want to do with a sword. I've seen people do that with bokkens and wasters and clock themselves in the back of the head with the "blade." Had they been live blades, they would have had severe lacerations on the back of their heads or necks. I used to do it with bokkens, but one time I would have been missing an ear had the bokken been a live blade.: It looks semi-cool, but serves no practical purpose in combat. It doesn't really impress anyone either, because everybody knows that all you're really doing is rotating your wrist.
