One of the handiest types of walking stick, found in both wooden staffs and telescoping poles, come with a compass embedded. If your GPS runs out of batteries and you no longer have a working electronic compass, that compass in your stick can make navigating out of the back country an easier task.
It is always good to have a strap on your stick or staff. Besides anchoring the stick to you if you let go of the handle, straps can help shift some of your weight from your hands to your wrists.
Some people insist a rubber cane type end is essential, letting you keep a better connection to the surface on which you are traveling. Others think a rubber tip can be precarious on wet rock or in the rain. Many handmade sticks merely have a flat bottom. And, there are sticks that have steel tips or ferrules to set themselves firmly into minute crevices in the trail or rock. For some people, those steel tips seem invasive, as they leave a trail of minute holes behind you in the dirt. However, one good rain will fill in any tip dents from your trek.
