Kanabo is a samurai weapon of feudal Japan, a type of tetsubo in the form of a metal club with a round handle, which has a thickening with a ring at the end, and, often, supplemented by small unsharpened spikes. 

Kanabo, like most weapons of the same type, was constructed from heavy wood or iron, with metal spikes or projections at one end. Its shape was the most varied: it could resemble a baseball bat, tapering from end to handle, or be completely straight from start to finish.

The size of the kanabo ranged from small sticks held with one hand to huge two-handed maces, the size of a person's height (up to 2 meters in length). It was primarily used to break the enemy's armor and cripple the limbs of his war horse. The art of wielding this bulky weapon was called kanabojutsu and consisted of training balance and strength while using the baton.
