';.;' Gram

In Norse mythology, Gram (Old Norse "wrath"[1]) is 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 in the hall of the Volsung after pulling it out of the tree Barnstokk into which Odin had stuck it—nobody else could pull it out. The sword was destroyed and reforged at least once. After it was reforged, it could cleave an anvil in half.
