- "My new blade. 'Hearteater' I've named it."
- ―King Joffrey Baratheon
Before leaving the Red Keep to oversee King's Landing's defenses against Stannis Baratheon's attack, King Joffrey orders Sansa Stark to see him off with a kiss. He then draws Hearteater and commands her to kiss it. He mentions that after the battle he will have her kiss it again and taste his uncle's blood. Sansa asked if that means he will be fighting the vanguard, as Robb Stark, who is only a pretender, does. Angered, Joffrey says that someday she can lick Robb's blood off Hearteater as well. Ultimately, Joffrey never wields the sword in battle.
In the booksEdit
In the A Song of Ice and Fire novels, Joffrey has a habit of frequently getting new and quite impressively made swords, and giving them fierce names like "Lion's Tooth" or "Hearteater", but he never actually swings a sword against an opponent at any time in the narrative. When he does personally execute people he uses a crossbow, because he doesn't actually know how to wield a sword.
