Another possible leatherworking tool?

[Cleave]

I found this in the $1 bin at the latest estate sale, underneath the garden trowels and Y valves... along with a B&S feeler gauge, Starrett radius gauge set, and a W. Butcher gouge. The best find was a great Briddell meat cleaver in the $3 random kitchen knife bin.

I asked my leatherworker brother in law, and my professional potter sister, and they don't know.
It looks like some kind of leather offset marker but nothing really makes sense yet.
Any guesses?

Pretty sure that’s a can opener.

You poke a hole in the center then go around the edge poking through with the triangle piece. It’s adjustable for different size cans.

Go to 4 minutes and 30 seconds

YES! That's it. Thanks, I'll have to try it out, my kids will find it hilarious too.
