GLIMA MJÖLNIR by Tyr Neilsen

When the Academy decided on making the ultimate glima symbol, it was agreed that it should be the symbol of Thor, the god of Viking wrestling - Mjölnir

Mjölnir, from the Old Norse - Mjǫllnir, meaning to "grind" or "crush", is the most powerful Viking sacred symbol. As a symbol, it was used in sacred Norse and Viking ceremonies, weddings, and as a protective amulet.
