I said Ninja Sword, not Samurai Sword. What's a ninja sword? It's shorter than a samurai katana, and a little longer than a wakazashi. Whether you think it was invented by Hollywood or not, THEY EXIST NOW, and are quite usable. Samurai only carried around 2 blades I'm pretty sure. Katana and Wakazashi. Tanto was kept for ceremonial acts like seppuku, I don't think they actually carried that on them. Oh, btw I was reading a few weeks ago that some generations of ninja actually used full size samurai blades.
