Sons of Ivaldi

Dwarves. The four sons of Ivaldi were master craftsmen.

On Loki’s advice, the sons of Ivaldi (“bowman”) created three gifts for the Aesir. They created a magic gold wig to replace the beautiful hair of Sif (wife of Thor). They also made a collapsible boat for Freyr called Skidbladnir. Whenever the god was not using the boat, he could shrink the vessel to a size where he can place Skidbladnir in his pocket. The sons of Ivaldi also made the invincible spear Gungnir for Odin.
