So. I like walking with a staff but I also like having multiple things in one. That got me thinking I would kinda like a light weight umbrella on my staff. Combined with the little end caps that allow it to stand on its own it seems like it could be pretty useful. Even better if it had a metal capped spike at the bottom.
Combine it with a small fold out seat in the handle and you’ve got the ultimate stick.
Oh your right and that mechanism would make the stake and cap unnecessary if it could be light enough. Need like carbon fiber and aramid or something.
