• The creation of Mjolnir (Thor's magnificent hammer)

    Mjölnir was the result of a contest between Loki and two dwarves, to see if they could create gifts for Asgard that were better than those the gods already possessed. Loki, of course, tried to cheat by interrupting their work but only succeeded with Mjölnir, causing the handle to be too short to be wielded two-handed. This made it hard for anyone lacking god-like strength to wield it.
