If I had a hammer....

Years ago I bought a toolbox from someone and there were a couple of
these small hammers made out of wood. The head is maybe 1 - 1 1/2
inches across, a couple of inches long. On one of them the head is
made of what looks like a wood strip that's been wound, the other is
solid. Either of them weigh a few ounces.

What would these be used for?
