Thor's Hammer with ancient Celtic knotwork and step pattern designs that are historical, along with the hammer shape, but the piece itself is not a direct reproduction. Thor’s Hammer, called Mjolnir, was the primary weapon of the Viking God of Thunder. It was both a fearsome weapon and a ceremonial object. It played an important role in rituals and ceremonies and was used for blessing during birth, marriages, and funerals. It was a symbol of destructive power but also a symbol of healing, and protection and security from the evil and violent forces.
