"In Chapter 76 of Njál's saga, Thorgrim and a few other grudge-bearing men were scouting around Gunnar Hámundarson's house. Gunnar woke up and stabbed Thorgrim through a gap with an atgeir (a type of spear). Thorgrim returned to his comrades, who asked if Gunnar was home. "Find that out for yourselves, but this I am sure of: that his atgeir is at home," he said, and fell down dead."
