Not necessarily to hammer anything. Various spikes on polearms have a lot of potential use for hooking, pulling, parrying, etc. This is easily big enough for that kind of thing.
Having it flush with the top makes it less good for this, but better for use as a striking weapon. A reasonable compromise.
As Lee wrote above, a hammer can be a very useful tool. If, however, this was a long-hafted battleaxe, it might be a rather clumsy tool, and maybe the main function of the hammer is fighting.
