Kanabō

[3] Related solid iron weapons with no spikes or studs are the kanemuchi (or kanamuchi) and the aribo (also known as a gojo or kirikobo).

Kanabō-type weapons came in a wide variety of shapes and sizes; though the largest ones were as tall as a man, on average they measured roughly 55" in length.

The Kanabō was typically intended for two-handed use, though one-handed versions exist which are more usually referred to as tetsubō and ararebō.

The shaft cross-section could be round (as in a baseball bat) or polygonal; that is, multi-faceted with flat surfaces arrayed around the central axis.

[5][3][6] The kanabō was also a mythical weapon, often used in tales by oni, who reputedly possessed superhuman strength.
