This article explores the depiction of extraordinary weapons in the Icelandic sagas, examining how they were imbued with lifelike qualities through their names, attributes, and implied personalities. These weapons represented a distinctive and hazardous anomaly, as they were perceived to possess both vitality and material substance simultaneously. One method of managing such anomalies involved forging agreements with the sword itself or with the individual presenting it as a gift. By doing so, the new owner committed to recognizing the weapon’s inherent qualities and character, treating it with a level of reverence akin to that afforded to sentient beings. The purpose of such contracts was to cultivate a sense of friendship between the weapon and its new owner. The supernatural powers believed to reside within these weapons could merge with the wielder if handled with care, requiring an ongoing awareness of the weapon’s desires and intentions. Consequently, the line between the warrior’s skill and the capabilities of the weapon often became blurred. However, there were no certainties; even the most skilled warrior could succumb to an angered or mistreated weapon. This phenomenon potentially contributed to the development of a belief that weapons endowed with unpredictable personalities could be responsible for accidents and unforeseen deaths without implying that the warrior lacked skill in battle or that he was struck by bad luck.
