Chains and Weights from Top 10 Samurai Weapons
Although the manriki-kusari (sometimes called fundo-kusari or weighted chain) gained fame as a ninja weapon, police officers actually adopted the weapon to disarm and capture criminals. No matter the wielder, the versatile weapon had many advantages. The collapsable chain could be rolled up, concealed and easily transported. It could be used for climbing, restraining an enemy, and could be wrapped around body parts for extra protection. In battle, a user could shorten his grip and taylor the length as a situation called for. Once in motion, a manriki-kusari moved at speeds that rendered it invisible. An experienced practitioner could swing the chain around himself to keep opponents at bay. Thanks to its weighted end, the manriki-kusari doubled as a projectile; its metal weight could be thrown to strike opponents. Yet unlike other throwing weapons like darts or knives which had to be retrieved to be used again, the manriki-kusari's weight returned to the hand of its wielder via its attached chain. The manriki-kusari could also ensnare and immobilize an opponent's weapon. The swinging chain could not be cut by a blade and would instead wrap around it, making it particularly affective against the katana. Once the chain entangled an opponent's weapon a skilled user could disarm an opponent. But manriki-kusari had disadvantages too. A difficult weapon to master, a manriki-kusari user could injure himself with the flying weight. Despite its adjustable nature, the manriki-kusari proved weakest in confined spaces like crowded or wooded areas where the chain could not be swung freely, limiting its power.
