Having googled halberds and poleaxes, the one thing that is notable in the above example is just how much mass and depth there is in front the shaft.
Most long shaft weapons seem to come with a counter balancing spike or hammer and the blade edge would be much closer to the shaft.
The example would appear to me designed for a downward swing only, swung in any other direction it must have a tendency to twist, not good in a weapon.
It does not appear to have a ceremonial finish, so that would imply use.
If you want blood and gore, perhaps its an abattoir axe, or its just an early log splitter.
