Never heard of Kanabojutsu, so I looked it up: According to Wikipedia, the Kanabo was used vs. armored Samurai and war horses (most likely in pitched massed warfare with limited maneuverability.) It further call this weapon "cumbersome...requiring great skill to recover from a miss with the heavy club, which could leave a wielder open to a counter-attack." It also states the obvious - great strength was needed to use it at all. So not an option for many martial artists. This entirely supports all my comments re: the use of a bat or other weighty weapons and supports my "whole claim."
