History
The Axe of Ymir was the enchanted axe used by Odin to slay the Ice Giant Ymir. Eventually, Loki stole the axe.[2]
Eons later, during one of his attempts to bring about Ragnarok, Loki called forth the Axe of Ymir from Limbo to battle against Thor in Jotunheim. The axe was ultimately destroyed by a blow from Thor's Hammer.[2]
