As I've said many times on this forum, the fictional character of Thor is a dangerous and violent person who clearly does not know how to handle a hammer safely or responsibly.
To set the record straight, here is an instructional video on how to use a hammer safely.
I feel it's important to spread this information in order to raise awareness that hammers are intended as tools for making things, and not as weapons with which to bludgeon your foes to death.
