I've absolutely had hiking poles in my hand luggage, wasn't a problem whatsoever.
I’ve had good luck getting trekking poles and stakes through in my carry-on, but according to the written rules they’re apparently not permitted 🤷
Time permitting, I'll swing by the ranger station or outdoor store (REI, etc.) on my way to the airport and see if the employees can use anything I can't fly back with, e.g. fuel cans or bear spray. I tell them how much I've used and they know there's no guarantee with them. Most of the time they'll gladly take it, even if it's just for their own, off-the-clock use.
That’s really thoughtful of you!
What about bear axes?
Overnight backcountry backpacking/hiking in the spirit of taking less and doing more. Ask yourself: do I really need that?
