I was at a seminar this weekend and saw a bit of Kukishin Ryu Bojutsu. The teacher used a special type of bo that I had not seen before and am having trouble finding information about. It had 9 metal bands on it: 1 in the center and 4 at each end. The end bands were space approx. 4-6" apart with the last bands being metal caps on the end of the staff.

I would attach a picture, but I can't find one! Any information about this type of staff (name, picture, etc.) would be greatly appreciated!
