I admit that while I've made lots of sticks, I use an old adjustable paint roller handle with a spike, while I fly fish.
It floats on a lanyard when not in use.
Funny that I've got staffs and sticks, but nary a wading stick. Moss slick rocky bottoms really need something to assist footing.
Several guys in our Fly Fishing Club use the fancy folding sticks, but I've never bought one.
I've just made do with the Paint Roller Handle cause It was there when I needed one.
