These 15th Century War Clubs, were used by Samurai Warriors for self defense (when a sword was considered inappropriate). 4 to 5 feet long, they were made of rattan or bamboo wood. Reinforced throughout the shaft with iron or brass mounted studs, they were used as a truncheon (bat). Whole “katas” were developed to properly train on in it's use. Some versions (smaller), were carried (much the same way as a modern Baton). Traditional versions required 2-handed operation. Some variations also included a small (2 to 3-inch) spike at the end. Also seen in combat, The Kanabo was used by “melee” troops to smash the legs of a charging enemy cavalryman (as well as his horse).
