Our Ninja sword is actually modeled after the Ninja-Toh used by ninja assassins and the Wakizashi worn as a secondary blade by samurai warriors. Traditionally, the wakizashi was slightly curved and much higher quality than the ninja-toh. Samurai warriors always wore the katana and the wakizashi, as a pair, on the same side. The ninja-toh had a straight blade and often included useful tools in the scabbard to help the ninjas in their dark trade. Our Ninja sword is 28 inches long with a two-handed handle and a single edge, similar to the Samurai sword.
