Origin
According to ancient Norse mythology, Mjolnir and other great weapons and ornaments were crafted by the dwarfs Brokk and Eitri as a wager, instigated by the trickster Loki, to see which was the better smith. Loki was desperate to replace the hair of Thor's wife Sif, whom he cut off as a prank, but he had no money to pay the dwarfs. He wagered his head that they could not create the wondrous things he described, including hair of gold for the lady Sif. After the items were wrought the dwarfs took them to the gods for inspection and payment. When Odin declared that he had approved no such deal, the dwarfs demanded the head of Loki, to which the gods did not object. Ever the cleaver trickster, Loki agreed that he had wagered his head but not his neck, when one of the dwarfs attempted to cleave it from his shoulders with a sword. Although their revenge was thwarted, the dwarfs sewed Loki's mouth shut and the gods had a time of peace and quite from the god of evil.
