The Dec. 2000 issue of Black Belt Magazine has an article,(Pg. 82-86), regarding cane use. It highlights the site -
www.canemasters.com.
My apologies if I missed it but you didn't mention the scene in BILLY JACK using the cane defense. We must remember that these items are tools of our craft. And we must master their use lest we become like the bad carpenters whom blame their tools.
Royal regards to one and all.
