In Norse mythology, the wolf heads on a Viking armband often symbolize the wolves Geri and Freki, Odin's companions, or the mighty wolf Fenrir. They represent loyalty, untamed strength, courage, and the duality of protection and destruction. Historically, such pieces of jewelry were crafted from materials like bronze, silver, gold, iron, or copper, while modern replicas are frequently made of stainless steel, silver, or leather.
