Hammer of Thor by Dryad Design's / Paul Borda. The great "Mjölnir", or Hammer of Thor, whose striking causes the sound of thunder, is the most fearsome weapon of the Norse gods. It is said to be capable of leveling mountains and slaying any foe, yet it can heal as well as harm. By waving the hammer over the slain, Thor could raise the dead. The runes around the edge of this hammer list the Nine Noble Virtues of modern Asatru.
