This is not a new idea, but one that, like the hollow handle survival knife rarely works well. A few items are nice on a staff; wrapped paracord to secure the all important wrist loop ( bring your hand UP into the loop and let it bear the wieght. Gripping a stick all day will exaust your hand), a tapered end to fit a Cold Steel Bushman for mimiking Ringo Starr in Caveman and some scribed measurements to determine the size of the bear that is circling back as you examine his/her tracks.
