The Rune Axe of Grimnir is a runic two-handed axe. Wielded by Grombrindal, it is an impressive weapon that increases the wielder's strength. 
It is dedicated to Grimnir, and matches the description of the Ancestor God's weapon found in several sagas. Perhaps it is indeed Grimnir's axe, gifted by him to the White Dwarf.
