The Black Rose is a promotional melee weapon for the Spy. It is a double-edged butterfly knife serrated on one side with roses engraved along the blade and a symbol of an encircled rose imprinted on the handles. Its Baccara style colors the weapon almost entirely black, while the Mystery and True Love style is team-colored.
It was avaliable as a promotional melee weapon for spy by playing "Alliance Of Valiant Arms" on Steam as a Free To Play game, but the game has since shut down, rendering it unavaliable.
