Gram (mythology)
In Norse mythology, Gram was the name of the sword that Sigurd (Siegfried) used to kill the dragon Fafnir. It was forged by Weyland The Smith and originally belonged to his father, Sigmund, who received it after pulling it out of a log into which Odin had stuck it—nobody else could pull it out. The sword was destroyed and reforged at least once. See Sigurd for more details on the story of Siegfried and Fafnir.Alternative name for Gram is Balmung
