“The Stick Man” in the UK makes wonderful wading "sticks" out of wood.
One of the ideas he incorporates into his sticks is weight in the form of lead wrapped around the stick near the bottom and coated with rubber. This keeps the wooden stick from floating behind you and becoming tangled with your fly line.
Another thing to consider is a rubber or wooden tip while quieter than metal, can be slippery as heck in certain places. I made a few WALKING sticks for some of my senior friends. I made them from heavy-duty varnished hardwood broom handles, available at any hardware store, drilled a hole at the top and added some paracord for simple lanyard.
To add a spike for ice, I simply drilled a pilot hole in the bottom/center, screwed in a #12 or #14 long shouldered stainless steel sheet metal or deck screw that I WAXED first so just the shoulder was exposed. Then I cut off the head of the screw with a Dremel Tool leaving the shoulder exposed about 3/8” and sharpened it.
Conveienienty, a rubber crutch-tip fits perfectly over the broom handle and spike and coincidentally, I found that a plastic backed 3/4” self-adhesive felt pad for a chair leg fit in the bottom of the crutch-tip which keeps the spike from poking through. A couple of stacked stainless steel washers glued in the bottom of the crutch tip would also accomplish the same thing AND add a little weight.
When the spike gets dull, I re-sharpen it, when it is worn, I use Vice Grips to back it out (which is why I waxed it originally) and I just put in a new screw and make a new spike.
I think the walking sticks cost me a few bucks to make out of a nice varnished broomstick and the other parts were available at a hardware store. I see no reason why the same thing couldn’t be made longer and called a wading staff.
Good luck!
