A Y-shaped weapon is a SLINGSHOT, which is a handheld device used to launch projectiles such as stones or marbles. It consists of a Y-shaped frame with two rubber strips attached to the ends of the arms. The user holds the frame in one hand and places a projectile in the pocket created by the rubber strips. When the user pulls back on the rubber strips, the projectile is launched forward. Slingshots have been used since ancient times for hunting and warfare.
