(under subclass 516) Subject matter wherein the projecting implement comprises an elongated shaft having a projectile striking head at one end thereof which is either (a) generally in the form of a sphere, cube, or other generally regular geometric shape or (b) a crossbar which, together with the shaft, forms a generally T-shaped implement and wherein an imaginary line, which passes through the center of a projectile striking area of the head and which is perpendicular to a reference plane located either tangentially to that center (if the striking area is curved) or congruently with the plane of the striking area (if the striking area is flat), intersects the shaft or an imaginary extension thereof through the head.
