Kunai - Ninjutsu Martial Arts Weapon

The Kunai was a traditional Ninjutsu weapon used by the Shinobi (or better known in the West as Ninja) during missions of espionage (spying), assassination, etc. It was a multipurpose tool that could be used for digging holes in walls, as a stabbing weapon, as a climbing tool, etc. Originally, the Kunai was based on a Japanese farming tool (i.e. gardening trowel).Traditionally only the tip of the Kunai was sharpened.
