Warning, this video shows a man cutting a pig carcass. it may be slightly disturbing. However it is not that graphic and there is no blood. First up, I find it puzzilng they refer to this guy as a Samurai. Wearing a kimono and having a sword doesn't make you an appointed liege of the Shogunate of Japan... Anyways, the katana he is using looks like one from the company "Last Legend". Very sharp, very durable blades. Geometry is better than the Paul Chen stuff, but polish and th quality of the fittings are a little below PC. The pig carcass apparently has been deboned, and with good cause, dead bone is incredbly tough. Living bone is much softer and spongier than the bleached stuff you pick off the desert sand. Even the popular show "MythBusters" didn't even know that, they tested a dead, dry human bone to simulate an experiment once. I sent them an email notifying them of that, but never got a response. Notice he is careful not to damage his sword. Just look at the size of the wound he created in the pig after the first stroke. The object of the sword fight is not to cut your opponent in half like so many Anime movies show, but instead to inflict a mortal wound that your opponent can't recover from.
