This isn't a hammer that you can buy at your local Home Depot. In fact, the hammer looks nothing like a hammer at all. It looks like a weapon one of the Starks will eventually use to slay a dragon on Game of Thrones. There’s no real world comparison to this thing, but the fact that you can decapitate yourself if your form isn’t correct certainly adds to the degree of difficulty.
