The only two people that I know who use a hammer to fight are Thor and Robert Baratheon. As far as I know, they are both fictional.
But Thor’s hammer is supposedly magical. It can be lifted only by the worthy. They now have the power of Thor.
There is only one hammer of this kind. And Thor has it, so it means he is worthy. Does this mean everyone else is worthless?
I’m probably wrong. Hopefully wrong.
