Because of the hidden tube stash I believe this piece can be referred to as a ckoe-cane. The tube can be used to hinde anything - cash, tickets, other small items...whatever.
As cool and unique as this piece is, it does need some re-hab. It looks like it may've been dropped at some point so the thread that the handle would screw onto and the tube are both missing a piece. The tube fits perfectly into the cane - the handle does not thread on tightly though. The threads are somewhat worn and it's also because of that missing piece.
Being old as is with the understanding that it needs repairs.
