The Katana

Infamous weapon for the Teenaged Ninja Mutant Turtles, Katanas to me seem like simple cut'em up type weapons but are far from it, it is a very complicated tool. The creation process itself takes months and cannot have any mistakes or else the entire process is in jeopardy. Maintaining a Katana even if you never use it is a chore because the metal can rust and become dull from moisture in the air, the wood can rot if not cared for and the blade once tarnished will be irreplaceable. I think the handling is extremely important because they are delicate and can be damaged if used improperly so dont let the kids play with'em. The Ninja's in movies make Katana handling look effortless but there are a number of sword training disciplines that teach the students how to use a wooden sword long before they are given access to a real sword.
