I have several, actually. I bought a few when I needed one, then when I could get around better, I made three of them from wood that grew in my yard.
Two are hickory and one is from an oak. The oaken one is very crooked, but I love it. It is natural and all I did to it after curing the wood was to whittle off the bark, clean up around the smallish branches I cut off, stain and oil it. It is actually my favorite, due to how I was able to shape palm piece. It is also too heavy, to use constantly, but as a "fashion statement" cane, it is very cool.
One of the hickories is actually quite a bit more practical, being quite thin and light. I actually planed this one down and tapered it sanded it forever with finer and finer grade abrasives, finally using "0000" steel wool for the last until it was shiny and then just oiled it.
The other hickory is more like a true "walking stick" than a cane. Comes up to my forehead and I always wanted to find a really Gandalf looking burl or branching thing to add to the top and maybe buy a cheap but huge lucite diamond cut crystal to mount in the grasp of the branches after mounting a powerful LED flashlight inside the stalk to light up the crystal when I wanted.
Might have to dig them out and take a pic.
