These weapons types were similar in type to the European Flail. Made of hollow wood (bamboo), they ranged from 2 to 3 feet long. An attached chain (varying in length – but “standard” as 15 to 18-inches long), the chain was attached to the wooden shaft. Finally, a weighted end (lead or bronze) was likewise attached to the chain. This weight would have spiked extensions or protrusions. Used in a whipping or striking motion, The Chigirki could inflict massive damage to an enemy. Some varieties were used as “blowguns” (owing to their hollow construction) – or the hiding of smaller dart-like weapons. In their evolution, Chigirki Flails became longer (up to 5 feet). They developed throughout Feudal Japan starting in the 13th to 14th Centuries.
