When I go hiking to a backcountry lake I use a metal rod case that I have attached a tennis ball to the end. The ball cushions the case on contact with the ground and rocks along the trail. To attach the ball I cut an x-shaped cut about the size of the end of the case then work it onto the end.
When you become "more mature" (older and your knees are not that good) the case as a hiking stick works well. At least that is my story and I am sticking to it.
