What items were made by the dwarves for the Norse gods?
On the Wikipage of Mjölnir, it is said to be made by the dwarves Eitri and Brokkr. Wikipedia also states that they created other items for the gods. Those items being: Skidbladnir, the ship of Freyr, Mjölnir, Draupnir and Gungnir.
"the Sons of Ivaldi are a group of dwarfs who fashion Skidbladnir, the ship of Freyr, and the Gungnir, the spear of Odin, as well as golden hair for Sif to replace what Loki had cut off."
"Eitri succeeded in making the golden boar Gullinbursti, the golden ring Draupnir, and the hammer Mjöllnir."
My question being, are there any other items that the dwarves made for the gods of the Norse mythology?
