Expand your search for walking staffs to include your hardware store where you can buy a replacement tool shovel handle. They make great hiking staffs, as does the carefully chosen branch for a suitable tree. I have lots of hiking staffs, being well into geezerdom, and my favorite was a somewhat modified branch. I do have a pair of collapsible sticks, and they are quite useful, since they can help hold up a tarp and can be shortened to tuck away on the pack when not in use.

Your shovel handle, particularly if you equip it with a metallic point, is now an alpenstock, a tool developed by shepherds in the 1500s and used by early alpinists until it was modified into an ice axe in the early twentieth century. Your hardware store may not even know they are selling them.

The thinner pricier collapsible staffs have another virtue. When used in fording fast moving streams, their smaller diameter gives much less resistance, and they are much easier to manipulate. Crossing a stream is just one situation where you will really appreciate them.
