Thor's Hammer - Mjölnir
In Norse mythology, Mjölnir is the hammer of Thor, a major Norse god associated with thunder. Mjölnir is usually interpreted as meaning "That which smashes", derived from the verb mölva "To smash" (cognate with English meal, mill); comparable derivations from the same root meaning "hammer" are Slavic molot and Latin malleus (whence English mallet).
An alternative suggestion compares the name to Russian молния (molniya) and the Welsh word mellt, both words are taken as meaning "lightning". This second theory would make Mjölnir the weapon of the storm god identified with lightning, as in the lightning-bolt or vajra in other Indo-European mythologies.
In the Old Norse texts, Mjölnir is identified as hamarr "a hammer", a word that in Old Norse could mean "hammer" as well as "stone, rock, cliff", ultimately derived from a Indo-European word for "stone, stone tool", h₂éḱmō; as such it is cognate with Sanskrit aśman, meaning "stone, rock, stone tool; hammer" as well as "thunderbolt".
Most practitioners of Germanic Neopagan faiths wear Mjölnir pendants as a symbol of that faith worldwide. Renditions of Mjölnir are designed, crafted and sold by some Germanic Neopagan groups and individuals. Some controversy has occurred concerning the potential recognition of the symbol as a religious symbol by the United States government.
In May 2013 the "Hammer of Thor" was added to the list of United States Department of Veterans Affairs emblems for headstones and markers.
