Gullinbursti

Gullinbursti (meaning `Gold Mane or Golden Bristles`) is a boar in Norse mythology. When Loki had Sif`s hair, Freyr`s ship Skíðblaðnir and Odin`s spear Gungnir fashioned by the Sons of Ivaldi, he bet his own head with Brokkr that his brother Eitri (Sindri) wouldn`t have been able to make items to match the quality of those mentioned above...
