thanks WM! I must watch how Sasaki Kojirō resheath his double-handed extra long katana in 'duel at Ganryu Island'....do you knwo whether the duel really happed on just stories?
Yes, it really happened - with Miyamoto Musashi. Musashi realised that due to the opponents blade length he needed something that would make it more fair or he was just a target at a long distance - too long for his blade to reach. So, he whittled down an oar a bit to make it more wieldable (is that a word? well, it is now) and used the oar and won.
There is an excellent book by Eiji Yoshikawa on the life of Musashi entitled, appropriately enough, 'Musashi'. It's written like a fictional story but is historically accurate. If you can get your hands on it (the library should have it) then by all means take the time and read it. It was orginally published in 1935 and comprises seven books. The English edition is 900+ pages. It's a good read and an entertaining and fun read. You are obviously already familiar with some of the movies made about the life of Musashi.
