knife

Had a few minutes to detect before class today
and hit the backyard of my father in law and only
got a few hits but one in particular really caught
my attention.
It was hitting between penny/dime and 6 inches
deep, so dug the plug and this knife pops out of it.
Anyone know anything about it?
Closed it is 3 and half inches, opened it is 6 inches.

Yeah, I always save the pocket knives that I find and use them for all sorts of things like cleaning other relics or if they're in good shape, I'll carry them for use.
