The Mammen Thor's Hammer type or carving is named for an ax that was found in Mammen, Norway. It was popular around the year 1000 AD. It is about 100 years older than the Urnes style. The design on this hammer shows a depiction of Thor in a traditional pose of holding his beard with the two goats that pull his chariot.

Thor's Hammer is properly named Mjöllnir, the hammer of the god Thor. The hammer has become a symbol often worn by folk of Scandinavian ancestry or by Asatru, Heathens and other Neo-pagans who honor the old Scandinavian gods. In Norse Mythology, Thor's hammer, Mjollnir, enabled Thor to "strike as firmly as he wanted, whatever his aim, and the hammer would never fail, and if he threw it at something, it would never miss and never fly so far from his hand that it would not find its way back, and when he wanted, it would be so small that it could be carried inside his tunic."
