Solid steel construction and all black – just how the ninja like it. Has an sharpened metal blade (not meant to be sharpened). The blade and the handle are a combined 13 inches long. Attached is a 10 foot long chain with metal ring.
The way the ninja would use this weapon is they would throw the chain at the samurai (or whoever was the opponent) and tie up the sword so it could not be easily wielded and then rush in with the knife hook.
