@Cheese, Interestingly my sensei practiced some Iaido and came in one less with a Katana to show it off. I wouldn't mind learning some swordsmanship, preferable Kendo, but I don't have any dojos nearby. Though that's didn't stop me & my dad (when I studied Karate) getting the bokken out and sparring in the back garden. Mind you we did that with other weapons - like the Bo and Nunchaku, a foam nunchaku, which turned out to be plastic on the inside (as we found out when we manage to break them). Once you've studied Karate, it's actually very easy to pick up a Japanese weapon and just use it - okay, things like the Nunchaku require a little extra training, but we only used a book for that and were amatuerish at it.
Quote: "like the start of this duel?"
Same opening move, but then you kick him in the male parts, elbow him in the face and snap his neck.
That video reminds me a little of a story about the Samurai in my avatar (Miyamoto Musashi), who when faced with a duel he got up late forgot his sword and made a bokken out of an oar. Essentially he took out (and killed) his opponent in a single strike, using essentially what was Iaido - the art of drawing your sword, killing your enemy in a single strike, wiping the blood off and sheathing it.

Also, the man wrote a really good book called The Book of the 5 Rings, definitely worth a read if you're interested in Samurai philosophy. Same for Tsunetomo Yamamoto's Hagakure.
