Gungnir it the name of Odin's mighty spear. Scandinavian art often depicts Odin with a spear. Such depictions are found from Viking Age rune stones all the way to Bronze age rock carvings of a spear god, who may well be Odin.
Same as the Hammer of Thor, Gungnir was forged by dwarves and Gungnir is no ordinary spear. Odin led the Aesir into battle against the Vanir beginning the battle by throwing Gungnir with a battle cry of “Óðinn á yðr alla!” (“Odin owns all of you!”).
He sacrificed himself to discover the runes by simultaneously stabbing himself with Gungnir and hanging himself. It’s fitting, therefore, that when the Norse sacrificed someone to Odin, whether a single individual or a large group of people, they typically did so by means of a spear, either by itself or in combination with hanging.
This Gungnir representation is made from Bronze and plated in fine Italian Silver. It hangs on a black cord and fastens with a metal clasp. On one side, the Valknut is carved and as per the stories depicting Gungnir, it has runes on the other side.
