"Jo was a lower class weapon, one rather beneath the dignity of a "real swordsman".
Of course they're smiling when they say that, but..."
Kim Taylor
To shift from the feudal "class" issue to the modern pov, my contacts in various martial arts and wooden weapons groups usually bring out the following prejudices:
Jo work (Japanese style walking stick length) is not practical as it is too stylized.
It is based on defending against a sword and so is out of touch except for historical purposes...if I wanted to engage in an out dated historical martial art, I'd go to the main weapon, the sword.
As a member of the Butoku Kai I have learned 3 jo kata. I think they teach skills that are very useful to today's cane and walking stick crowd but I'd get nowhere teaching them as a separate ryu...I just add them into my technique repetoire and teach the skills as Cane skills based on the jo.
