Sword of Kas

The Sword of Kas is a sentient, versatile black longsword formerly wielded by Kas the Betrayer when he rebelled against Vecna millennia ago. The blade seeks blood and the downfall of Vecna, and is legendary for being the weapon that carved the Hand and Eye of Vecna from the lich during Kas' epic battle against him.
The blade would later be wielded by Rasper Gouliak who would rename it to the Sword of Ras.
