I know nothing about it's age, and even less about it's purpose. Iím not even sure itís a woodworking tool.
The wedge and ring are steel, and the split piece is some kind of wood.
We're not even sure if it's assembled correctly.
Itís been suggested that it might be a ďfeather & wedge setĒ, used the cut/break stone. But the wood on this thing is as smooth as a baby's butt (top to bottom). I just can't believe it's ever been driven into a hole in a rock.
