This sword is the sword of Hrethel, which Hygelac gave to Beowulf. Nægling is a bright, strong, and might sword with a venerable history as a precious, ancient heirloom. However, the sword does not survive Beowulf's final encounter with the dragon in one piece. It was snapped in two, not because of the dragon's strength, but because of the Beowulf's.
