MJOLLNIR Hammer of Thor Used as both a devastating weapon and a divine instrument to provide blessings. The hammer was commonly worn as a pendant during the viking age and still is to this day. Mjollnir was created by two dwarves Brokkr (Metalworker) and Sindri (Spark Sprayer) Loki, who represents recreation, mischief, deception and malevolence bet the two dwarf brothers that they could not forge creations equal to that of the sons of Ivaldi. Loki waged his head, Brokkr and Sindri accepted the bet. As the dwarves went to work Loki disguised himself as a bee and stung Sindri's hand. This caused the dwarf to pull his work out of the fire and Gullinbursti (Golden Bristled) a living boar with golden hair was created. Sindri resumed his work this time with gold as Brokkr worked the bellows. Loki stung Brokkr on the neck and Sindri pulled out the ring Draupnir from which eight new rings fall every ninth night. Sindri now put iron on the hearth and told Brokkr they cannot make any more mistakes. Loki quickly stung Brokkrs eyelid as the blood flowed it blocked Brokkr's eye, this prevented the dwarf from being able to see clearly. Sindri still managed to create the hammer Mjollnir (Lightning) that was unsurpassed in quality, would never miss it's mark and return to the owner after being thrown. Its only flaw, the handle was short. Confident of the worth of their three creations Sindri and Brokkr went to Asgard to claim their wages. Loki however made it to Asgard before the dwarves and gave to Thor the hammer Mjollnir. To Odin the ring Draupnir and the spear Gungnir. The gods were so impressed and grateful for these creations they agreed that Loki still owed his head. When the dwarves went to claim their prize Loki stated that he did not bet his neck. Therefore the dwarves had to be content with sewing Loki's mouth shut.
