Mjolnir:
Mjolnir was created by the Norse God Odin to test his son’s worthiness. The great hammer has the inscription “Whosoever holds this hammer, if he is worthy, shall possess the power of Thor.” Odin’s son started out with pride in his heart, but after his banishment to Earth to live as a mortal by his father, he finally claimed his worthiness to become the worthy owner of the mighty Hammer.
