Ninja swords? I think a ninja would be 1,000x more likely to kill you with a rock, a hammer, or something easily disposed of. If they had swords, I don't see why they would use them. It'd be evidence, then. Also, why would they wear swords? That would give them away as tough-guys, and kind of ruin their disguise, unless they were disguising themselves as samurai. but then they would wear samurai swords…not special ninja swords. The whole idea of a "ninja sword" is counter-intuitive and illogical. Did ninjas wear signs around their necks that said "I am ninja?" The japanese sword is the best hand-to-hand weapon for killing an unarmored or lightly armored enemy. Japanese swords are so great due to many facts a) Metal ores are rarer in Japan than in the mainland, so if you were going to make something metal, you would make for damn certain that it was worth the expense of the materials. b) There were a lot of wars in Japan. Land there is scarce and no one wanted to lose their land to invaders, yet there were always invaders. War means weapons. The weapon of the day was the sword. c) Japanese sword makers were kept an ellite bunch. Very patient and developed. This is partly or mainly due to a and b. But, as I've said before, Japanese swords were designed to slice people in half. They were not designed to penetrate plate mail. European weaponry was designed for this. Two totally different purposes and styles. A warhammer was designed to poke through a helmet, a flail was designed to poke through a helmet, and most later european swords were designed to umm poke through a helmet. Anyone know what a lance was used for? Japanese odachi and nodachi were huge fucking swords, but difficult to weild and uncomfortable to carry. They would be pretty much impossible to control indoors, and were pretty damn rare. Nagintas and other pole arms were more often used against cavalry than swords, but it's still cool.
