Zelda's Swords

Although they have yet to be individually named like Link's swords, Princess Zelda has on more than one occasion been seen possessing or wielding a blade of her own.

Legend of Zelda Valiant Comics
Despite being better skilled with the bow Zelda does at times wield Link's Magical Sword in battle.

Zelda's Adventure
In Zelda's Adventure, the sword is used as a spell through her default weapon, the wand. Using the wand, Zelda can generate broadswords that fly at her enemies. It is fairly strong and can be used against certain knights who fight with broadswords.

Twilight Princess
In the promotional pictures for Twilight Princess, Zelda is seen in possession of a sword and she indeed wields it against Link when she becomes possessed by Ganondorf, although not in hand-to-hand combat.
