It is authentically known that kunai is a tool from ancient times. Warriors began to use the knife as a cold weapon that was used in battles with enemies. A distinctive feature - a ring for pulling out the rope appeared at the moment when it was necessary to make a weapon out of a blade. This is the story of the appearance of the knife.

With the help of the resulting device, ninjas could climb walls, or trees. The kunai was transformed into a kind of steel hook. But in the process of fighting was used as a tool that can damage the opponent. To date, a special knife is used only in everyday life. The tool was a combat weapon only in ancient times.
