Key chain in the form of the hammer of Thor, from the film Thor.
The hammer of Thor, or more correctly, Mjolnir, is what it is called and means the Crusher.
It is believed that he was forged disproportionately to his weight, making a very short stick. And all because of Loki’s mischief. The hammer has so much weight that no one person can lift it. Only decent, can lift and use a hammer. With the help of a hammer, Thor could strike with lightning, as well as “fly.”
Hammer destroyed Hela, at the first meeting with the Thor.
