Abstract
A hand-thrown projectile having an enlarged head made from a soft material. A shaft has a semi-flexible section and a flexible section. The flexible section is interposed between the semi-flexible section and its rear end. The flexible section is created by flattening the plastic of the shaft into a wide, easily grasped tab. A plurality of stabilization fins are provided that radially extend from the semi-flexible section of the shaft. To toss the projectile, a person grasps the flexible tab. As the projectile is thrown, inertia and the acceleration forces created by the throw cause the semi-flexible section of the shaft to bend and store spring energy. Upon release of the flexible tab, the energy stored in the bent shaft is released and is transferred into the initial velocity of the projectile.
