The Leviathan Axe is introduced in God of War (2018) as Kratos' main weapon throughout the Norse Era. Specifically forged by the blacksmiths Brok and Sindri to fight off the power of Mjölnir, the Axe has been granted to the Guardian before the latter offered it to Kratos prior to her death.

Kratos brings the Blades of Chaos with him to the Norse realms, but instead of wielding them, he initially hides them under the floorboards of his family's home. The blades remind him too much of the past and the monster he was, so it is understandable that he doesn't want to see them, much less use them.
