Episode 8: Extraordinary Ninja Tools - Kunai and Ikibukuro *RERUN
The ninja employed a wide range of tools to accomplish their missions. In this episode, we introduce the kunai and examine what it was made of and how it was used. With the help of a leading ninja researcher, we also recreate and test the ikibukuro, a previously unknown tool that is said to have enabled the ninja to perform tasks underwater.
The kunai was a versatile tool used to climb stone walls, smash locks, dig holes and more.
Made out of carbon steel, the kunai could be used to start fires.
The ikibukuro was used by the ninja when performing tasks underwater. It did not release bubbles and freed up the ninja's hands.
