In the Shanti Parva of the Mahabharata, Bhishma gives advice to Yudishtra and the Pandavas concerning how to be a good king and how to be good person, while he's lying on a bed of arrows after the end of the Kurukshetra war. At one point, Yudishtra's youngest brother Nakula (an accomplished swordsman) asks Bhishma about how the first sword was created. Bhishma tells the story of how long ago, the Asuras (demons) were causing mayhem throughout the world. In response, Brahma conducted a great Yagna (fire-ritual), and out of the fire of the Yagna came Asi, a being who turned into the first sword ever created. Brahma gave the sword to Shiva, who used it to defeat the Asuras in battle.
Here's how the sword was passed down after that:
The divine Rudra [Shiva], after this, gave the sword, that protector of religion, dyed with the blood of Danavas, unto Vishnu with due adorations. Vishnu gave it unto Marichi. The divine Marichi gave it unto all the great Rishis. The latter gave it to Vasava [Indra]. Vasava gave it to the Regents of the world. The Regents, O son, gave that large sword to Manu the son of Surya....
In time Manu installed his own son Kshupa in the sovereignty of all creatures, and gave him the sword for their protection. From Kshupa it was taken by Ikshvaku, and from Ikshvaku by Pururavas. From Pururavas it was taken by Ayus, and from Ayus by Nahusha. From Nahusha it was taken by Yayati, and from Yayati by Puru. From Puru it was taken by Amurtarya, From Amurtarya it descended to the royal Bhumisaya. From Bhumisaya it was taken by Dushmanta's son Bharata. From Bharata, O monarch, it was taken by the righteous Ailavila. From Ailavila it was taken by king Dhundumara. From Dhundumara it was taken by Kamvoja, and from Kamvoja it was taken by Muchukunda, From Muchukunda it was taken by Marutta, and from Marutta by Raivata. From Raivata it was taken by Yuvanaswa, and from Yuvanaswa by Raghu.
From Raghu it was taken by the valiant Harinaswa. From Harinaswa the sword was taken by Sunaka and from Sunaka by the righteous-souled Usinara. From the last it was taken by the Bhojas and the Yadavas. From the Yadus it was taken by Sivi. From Sivi it descended to Pratardana. From Pratardana it was received by Ashtaka, and from Ashtaka by Prishadaswa. From Prishadaswa it was received by Bharadwaja, and from the last by Drona. After Drona it was taken by Kripa. From Kripa that best of swords has been obtained by thee with thy brothers.
So after all that illustrious history, the divine sword Asi was finally given to the Pandavas by their teacher Kripacharya, presumably during the time of their education.
So my question is, what happened to the sword after the time of the Pandavas? First of all, is there any occasion in the Mahabharata where any of the Pandavas actually used the sword? And what did the Pandavas ultimately do with it? Did they give it to Arjuna's grandson Parikshit, who took over the kingdom after the Pandavas went to the Himalayas? Was Asi passed down through the generations of the Kuru dynasty?
