Chigiriki is a Japanese type of mace used by the ninjas. It consists of about 60 cm wooden handle and 60 - 70 cm metal chain to it, with a ball with a spike at the end of the chain. There are chains that are simply fixed to the top of the rod, and those that are placed in a cavity inside the rod and are called swinging rods. There are uses such as hitting the opponent with a weight or winding to seal the movement. Most techniques for using chigiriki are included in chigiriki-jutsu practices, which is part of the training in araki-ryu koryu - an ancient martial art, founded in early 1570 by Araki Mujinsai Minamoto.
