The kanabo (金棒) is large wooden club with metal studs or spikes. It is around four feet in length and weighed around fifteen lbs. The kanabo is strong enough to bend or break weaker weapons like a katana.
Kanabo and the other related types of these club-like weapons were constructed out of heavy wood, or made entirely from iron, with iron spikes or studs on one end. One or both ends of the wooden type clubs could be sheathed in iron. Kanabo type weapons came in all sizes and shapes with the largest ones being as tall as a man and a two-handed weapon while the smaller lighter ones were primarily one-handed and the length of a forearm.
