The Stealth Fire (Japanese: ステルスファイア) is a yo-yo licensed to Bandai by Yomega and released for the Hyper Yo-Yo line in September of 1997. It is a variation of the Fireball featuring a narrow wing shape, which allow players to perform string tricks more effectively than with the regular convex profile. It was adapted overseas in North America as the Saber Wing Fireball.
