OK, it's a variation on a pocket keyhole that engages a wooden head. The head
is tripled, and cut curvy so after it bottoms, it'l at least start to slide into the
narrow part where it'll hold.

I'd be tempted to brush a little linseed oil into the receiving slot before assembly.
There's some interesting puzzle-box possibilities, after joining a panel you could
slide a second panel into position that blocks the first from loosening.

I could produce such a router bit with a few minutes of grinding, on a straight bit,
and make the dowels by working the router bit against a blank in a lathe.

You could use it, for instance, to mount a skirt to a tabletop.
