Ninja Hidden Kama with Wood Sheath

The kama was a tool used to cut weeds and bring in the crop. It was a very simple but very sharp and potentially deadly weapon. Its structure however made it very weak when attacked with heavy blows directly to the blade. Therefore, there has been a redesign of the weapon, which is called natagama. It is stronger in its construction, because the blade runs through past the curve of the normal kama and all the way down into the handle. This makes the cutting edge bigger, and above all, the previous weak point where the sickle was attached to the stick has disappeared.

This ingenious device can be used as a brutal ninja weapon!
