Looks like an axe to me. The cutting edge of the axe is embedded into the surface. And the handle attaches near the back of the head like an axe. Most hammers I've seen the handle attaches in the middle.

I believe it's actually trying to render a splitting maul, which people often confuse for an axe.

There are many different styles of axe and some don't flair out much.
