Thors Hammer flag

Mjölnir (from Old Norse Mjǫllnir) is the hammer of the thunder god Thor in Norse mythology, used both as a devastating weapon and as a divine instrument to provide blessings.

The hammer is attested in numerous sources, including the 11th century runic Kvinneby amulet, the Poetic Edda, a collection of eddic poetry compiled in the 13th century, and the Prose Edda, a collection of prose and poetry compiled in the 13th century.

The hammer was commonly worn as a pendant during the Viking Age in the Scandinavian cultural sphere, and Thor and his hammer occur depicted on a variety of objects from the archaeological record.
