  • While Death Battle declares the Ninjaken as a Hollywood invention; this is actually debatable. Japanese Ashigaru wielded swords that closely resemble the Ninjaken; although they were rarely as straight as Leonardo's design. While Miyamoto Musashi is credited with inventing Japanese duel-wielding swordsmanship; there are no accounts of real Ninja using swords in this manner.
