A throwing device includes an approximately straight and elongate shaft extending distally from a proximal end thereof to a distal portion of the device. The distal portion includes projectile retainer and a projectile track extending distally from the retainer to a distal tip of the device. The projectile retainer, when in a closed position, holds a projectile in a fixed position with respect to the device. When the shaft is gripped and swung through an arc, and the retainer opens to release the projectile, the projectile is propelled along the projectile track, by the swinging motion.
