First of all, I’m sorry if it’s not a katana. I think that’s what it is. Now on to the point. You know the scene. Marsellus is being raped by those damned hillbillies, and in walks Butch with the katana. He slashes the one, but watch. As points the sword at the second, but then it shows Butch’s face and he flips the sword around a second time. I don’t know if everybody already noticed, but try it out if you haven’t, preferably with a pool stick (how I demonstarted it.) It’s not possible how he does it. Well, that’s my two cents.
