    Don’t know of this is the sort of thing you’re looking for. It comes with a removable cap for using it as a cane. Beneath the cap is a metal spike, but it’s not sharp. It’s good as an umbrella and is extremely, absurdly, strong. I’ve heard the handle can get kind of gummy if left in the sun, but I haven’t had that problem. Be forewarned that the marketing for it is a self-indulgent cesspool of mall ninja, incel, “alpha male” defensive violence fantasies. It is a good product, though.

  • 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.
