Hrunting, a sword handed down from Hrothgar's forefathers.
In the Battle cave when Beowulf is fighting with Grendel's mother.
Beowulf credits Unferth for the sword he finds in the underwater den. He acknowledges Unferth's gesture in lending him the weapon for the battle against Grendel's mother.
In Beowulf's battle with Grendel, he fails to defeat him with weapons, resorting instead to using his bare hands. In his battle with Grendel's mother, he fails to kill her with his sword, Hrunting, and relies on a magical weapon instead. Finally, in his battle with the dragon, Beowulf is mortally wounded as his sword breaks, resulting in his death.
He needs to use a weapon this time.
Beowulf discovers that his sword is ineffective against Grendel's mother's tough skin. He discards the sword and instead uses a magical weapon found in her lair to defeat her.
While fighting Grendel's mother Beowulf finds his sword does not work against the monster. He discards it and takes Grendel's mother's weapon. Most men would not be able to lift it. He then beheads the monster.
After Beowulf kills Mother Grendel, Beowulf seeks Grendel and beheads the beast.Grendel's blood melts the sword.
These lines from the poem "Beowulf" refer to a sword that the Geat warrior finds among the treasures in Grendel's mother's lair. The sword is described as an ancient, giant-made weapon with an extraordinarily sharp edge. It is a prized heirloom and an unmatched weapon, except in the hands of an exceptional warrior like Beowulf.
An example of a simile in Beowulf's last battle is when his sword is described as "gleaming like a blood-stained icicle." This comparison illustrates the sharpness and deadly nature of his weapon.
These lines from Beowulf refer to the sword Beowulf uses to kill Grendel's mother.
When Beowulf swung his sword at Grendel's mother's head, the sword failed to penetrate her skin due to the enchantment that protected her. This encounter led Beowulf to realize that he needed a different weapon to defeat her.
Beowulf tries using Hrunting, the sword the Danes had given him, to attack Grendel's mother because the mother wanted to avenge her son's death and was followed into her home in the lake by Beowulf. Beowulf's weapon was Hrunting and so he tried attacking the mom because of her previous actions (avenging the death of her son Grendel- the monster Beowulf killed- by killing a close friend of the king Hrothgar who's men were killed by Grendel, and retrieving Grendel's arm that hung from the rafters of Herot after the battle when Beowulf hung it there from tearing it off Grendel).
