Örvar-Oddr's saga contains a notable account of blood brotherhood. The Norwegian warrior Örvar-Oddr felt a desire to test his fighting skills with the renowned Swedish warrior Hjalmar. Thus Örvar-Oddr sailed to Sweden with five ships and met Hjalmar, who had fifteen ships. Hjalmar could not accept such an uneven balance of strength and sent away ten of his own ships so that the forces would be even. The two warriors fought for two days with a lot of blood-letting and poetry, but it was a draw. Finally, they realized that they were equals and decided to become sworn brothers by letting their blood flow under a strand of turf raised by a spear. Then, the strand of turf was put back during oaths and incantations.
