The sword wielded by Eddard Stark in Game of Thrones is called Ice.
Ice is the ancestral greatsword of House Stark and is made from Valyrian steel, a rare metal famous in Westeros for its strength, lightness, sharpness, and distinctive rippled appearance. The sword is unusually large: it is a two-handed greatsword rather than the smaller blades commonly carried by knights.
Eddard uses Ice most notably in the Stark tradition of carrying out executions. Its name reflects the imagery and identity of House Stark, whose seat is Winterfell in the frozen North. The weapon is more than a practical tool; it represents the family’s authority, history, and responsibility to administer justice.
After Eddard’s execution, Ice is taken by the Lannisters and melted down. The metal is reforged into two smaller Valyrian-steel swords: Oathkeeper, later given to Brienne of Tarth, and Widow’s Wail, associated with Jaime and the royal family. Thus, Ice disappears as a single blade, but its steel continues to shape the story.
