Swords are actually a less-common Viking weapon; preferred weapons were spears and short knives. However, swords were carried by kings and other high-class Vikings, and were often named for their heritage, supposed magical qualities, or important events. These names allowed the weapon vast cultural significance, as well as cultural value; swords were passed down through generations. Names were often dramatic:

Gramr (Fierce), Grásíða (Grey-sides), Gunnlogi (Flame of Battle), Fotbitr (Foot-biter), Leggbir (Leg-biter), Kuernbut (Millstone-breaker), Skrofnung (Gnawer), Nadr (Viper), and Naegling (Hole-maker).

This type of name was said to give the sword immense power, drawing on the power of the trait, attributes, or history that it referenced. Names that referred to lineage or heritage could draw on the power of the entire heritage of its past; names that referred to animals, such as "Bear," could channel that animal's power during battle. While some warriors carried swords in battle, they were usually considered heirloom weapons, and the more pragmatic spears and axes were not often named. Named swords were also of great monetary value, and considered very important in the continuation and honor of a given family, clan, or dynasty.
