The diversity of ninja weapons and attributes is much wider than that of the samurai. The main weapon of ninja was the sword. Ninja swords were usually shorter than samurai katana and had a straight blade. When they climbed, the sword was put on the left shoulder, putting the handle of the sword was close to the left ear. Ninja also used different types of throwing knives, and a weapon for their fists called tagaki. They used metallic claws on their feet which helped them to climb and made their kicks more dangerous.
