Khazid'hea

Khazid'hea is a fictitious sword in the Forgotten Realms setting. Khazid'hea means "Cutter" in the Drow dialect.

Khazid'hea is a finely crafted blade that can cut through flesh, bone, armor, and even rock. The blade itself is sentient, and can project its “thoughts” into her head and even affect her reasoning. On the occasions this has happened, she has gone into battle against impossible numbers without realizing it until her enemies lay dead before her. In the process, she often gets hurt, but doesn’t notice. Khazid'hea is always hungry for blood and battle, and it is never sated.

Khazid'hea has one desire: to be held by the greatest warrior. In efforts to do so, it will alter its hilt to appeal to its wielder. In order to become the weapon of Dantrag Baenre, it shaped itself into a demon's head. While attempting to snare Drizzt Do'Urden, it changed its handle into the head of a unicorn (the symbol of Mielikki). When it accepted Catti-brie, Khazid'hea adopted the form of the panther Guenhwyvar, with the symbols of the dwarven gods etched into its side.

During the conflict with Obould, Catti-brie is wounded and is unable to engage in combat. Thus Khazid'hea ensnares Delly Curtie, Wulfgar's jealous wife, and the power of the sword, too great for Delly to control, consumes Delly and soon after leads to her death by a group of orcs. Though Cutter was wielded by several of the pathetic orcs, it eventually found its way into the hands of Drizzt Do'Urden who uses it during his fight with Obould Many-Arrows. He loses the evil blade after it gets stuck in Obould's armor. Khazid'hea is now wielded by Tos'un Armgo after he found it in the armor left behind by Obould Many-Arrows.

This weapon shares some similarities with Michael Moorcock's Stormbringer, another sentient, bloodthirsty, supernaturally sharp sword that could sometimes influence its wielder's actions. Also similar to it is Umbra, a sword in the Elder Scrolls universe which can possess a wielder in similar fashion, and is usually the game's strongest weapon.
