Mjolnir (Thor's Hammer)

In Norse mythology, Mjollnir also called a hammer of Thor, a major god associated with thunder. Distinctively shaped, Mjollnir is depicted in Norse mythology as one of the most fearsome weapons, capable of leveling mountains.
Typically used in Pagan traditions with a Norse background, such as Asatru, this symbol represents the power of Thor over lightning and thunder.
The early Pagan Norsemen wore the Hammer as an amulet of protection long after Christianity had moved into their world, and it is still worn today.
