I’ll never get around to doing it but here’s an idea someone can run with. Take a hiking stick, put a quick connect fixture on the top of it that accepts a similar fixture on the butt of a 9” blade.
Instant spear.

Cold Steel Bushman

The Bushman fits a standard garden hoe handle. Hoe handles make a nice walking stick.

Those are nice. I'm looking for something a bit more discreet.

Like having an old M3 combat knife on your hip and a staff (hiking stick) with a quick connect adapter to accept the blade.

It would be a less threatening way to have access to a spear until the time came when you might need it.
