Ninja Swords

Traditional Japanese ninja swords are distinctive weapons - they tend to be shorter than Samurai swords and have straighter blades, usually around 24 inches long.

The sword’s scabbard is 3 to 4 inches longer than the sword itself, concealing a hidden compartment that is used to hide small knives or bottles of poison.

The tip of the scabbard could also be used as a detachable snorkel, for underwater concealment.
