The Wakizashi is a traditional Japanese sword. In Deadliest Warrior: The Game, it was one of the Close-range weapons of the Ninja.
The wakizashi was a sword similar to, but shorter than the katana, with a blade about 18 inches (43 cm) in length (the katana typically being 6 to 12 inches longer).
The wakizashi was typically carried by the samurai as a sidearm, used when the katana was lost or broken in battle. It was also worn indoors when custom dictated that the katana be left at the doorstep, as its shorter length made it more maneuverable indoors.
