Not with a head that shape.Could it be a form of geological hammer. They are in a few forms and weights.
Its just the type we used picture framing when I was young. Laid flat against the back of the glass, mount & backboard to tap in pins prior to taping up. I've used them reglazing single glazed windows laid against the glass inside the rebate to tap in pins prior to puttying.My guess would be a picture framing or glazier's hammer.
for cobbling perhaps? - they sometimes have a peen off set to get closer to the welt / sole
