Rati

Rati is the auger, a boring tool, that Odin used to reach the Mead of Poetry. The giant Suttungr kept the mead inside the mountain Hnitbjorg, guarded by his daughter Gunnlod. Calling himself Bolverk, Odin worked a summer for Suttungr's brother Baugi in exchange for a drink, and when Suttungr refused, he brought out Rati and had Baugi bore through the rock. Baugi first tried to cheat, but Odin blew into the hole and the chips flew back at him. Then he slipped through as a snake, spent three nights with Gunnlod and flew off as an eagle. Hávamál recalls how Rati's mouth gnawed through the stone.
