speaking from Kobudo, where the Yuwara Bo (about 6 long, about 3/4 thick, made of wood for pocking, locking, thrusting and generally what you would expect from a small stick) is a recognised and taught weapon i can see its uses - but an entire sub-secton of Ju-Jitsu devoted to it... hmmm, havnt checkout out the site or anything else other than read your posts... but still odd :/
