The incident of Gram being pulled from the tree by Sigmund within the halls of King Völsung is a legend of a "sword of selection" originating with the sword Merodach. Gram itself, "the sword of supremacy in the tree" from Northern Europe, was the model for Caliburn, the sword in the stone possessed by King Arthur.
An uncommon Noble Phantasm that came into existence as a magic sword, despite possessing the attributes of the sun. Bestowed by his ancestor Odin, this sword is a rare weapon that not only selects a king, but simultaneously brings about glory, jealousy, ruin and fate. Its design differs between Gilgamesh and Sigurd's possession of the weapon, no doubt due to the reforging it underwent.
Sigurd’s Demonic sword, Gram, was once shattered into fragments in a clash against Odin's Gungnir, by Sigurd's father, Sigmund. However, through the process of restoration, Sigurd has reforged the weapon, having connected the broken segment of the blade to the pommel, thus making it a double-blade Sword. It glows emerald for some unknown reason.
Bölverk GramEditBölverk Gram: Heaven's Wheel of Destruction (壊劫の天輪, Guramu?) is the Noble Phantasm of Sigurd. The full power release of Gram, which is originally an Anti-Unit Noble Phantasm. Instead of releasing energy from the sword, Sigurd draws out the power of the sword and throws it as an "Anti-Fortress" Noble Phantasm.
"I think throwing it is more effective" is what he believes.
The thrown sword strikes the target while scattering flames, and right after that, Sigurd slams his fist into Gram's hilt at full strength. Bölverk means "he who causes disasters", which is an alias of Odin, his ancestor.

 Fate/stay night - Weapon Menu: Gram [T]
Demonic Sword, Sword of the Sun, Gram.
A demonic sword of ruin and glory that Sigurd, the greatest hero of Northern Europe, possessed in the Volsunga Saga.
It is the model of Caliburn in the legend of King Arthur. As Caliburn was a chosen sword in a stone, Gram was also a chosen sword in the mighty tree of the Volsunga king.
The legend of Gram and its possessor Sigurd is a story filled with glory and ruin, as one would expect from a great hero.
"Der Ring des Nibelungen", composed later in Middle Ages Germany, is the story of a knight equal to the legend of King Artnur, and the sword Gram changes its name and appears in it as Balmung.
As the "strongest demonic sword" equaling the "strongest holy sword", it even possesses the special characteristic of "dragon slayer".
