This is old Biff Tannen's fist cane as seen in Back to the Future II. The cane is about 3 feet long.It is sized and tapered precisely to the one that old Bill carries in the movie. Second, it allowed Biff to manipulate and swing it around rapidly, as he does when rapping Marty on the head, and when he gets out of the DeLorean, breaking the top off.
