I like hiking sticks, and have several. Bamboo is fine, lightweight, but not quite as tough as I like. Rattan suits me better (Cold Steel lathi's). I also cut hickory for some of my walking sticks, here's a few tips. Peel the bark, if you want it peeled, asap after it's cut. It's tough after it starts to dry. Use an eye-hook or drill a hole or just tie a timber hitch to one end and hang your peeled sapling(s) in a garage, barn, somewhere unheated. Or, if you have a lot of saplings, tie them tightly in a bundle and let them hang for a month or two, no warping. I stain mine and wipe them down with mineral oil once a year.
I also use Eastern Red Cedar, light, fairly weatherproof, and attractive. And they're a 'weed tree' around here, easy to harvest. I peel the bark and remove all the limbs, tie your sapling up and let it hang to dry. After it's dry, a coat of mineral oil and I carry it around in the bed of the pickup, the weather doesn't beat it up badly.
Third tip, I harvest straight buckeye & hazel sprouts from overgrown groves along the railroad right of way. Sooner or later the railroad will come along and spray them with weedkiller, so I'm not robbing anyone. They're light, straight and tough. I leave the bark on these, except at the end. As much as I like machetes, I carry a folding packsaw to harvest these and a couple of hanks of twine to tie 'em into a bundle.
Ferules, or the piece on the bottom of the staff. I often use rubber 'chair & cane tips' from the hardware store, they work fine but I'll also cut a 1.5" section of copper pipe and whittle the end of the stave to just fit snugly, then hammer it on.
