Whatever you do, don't get into a fight with Japanese samurai Isao Machii! If he can cut a rubber bullet fired straight at him in two, then chopping off your noggin is trivial. Yup, you read that right: he can cut a bullet in two.

"If he can see it well enough to cut it with his sword it begs the question as to WHY he would want to? Wouldn’t a real samurai just dodge it and not risk his blade?"
It seems to me that you all are missing the point. This demostration is for show. And everything that he does is very difficult. Let's see any of you or even anyone trained in kenjutsu cut an airsoft bullet in flight. Or a pea pod in half for that matter. How old are you kids, like 10 or 12? Because that's what it sounds like.
