ABSTRACT:
The generally spherical handball includes a first spherical surface portion at a common radial distance from the ball center and a second spherical surface portion at a second common radial distance. In a preferred embodiment, a third surface portion is defined at the second radial distance. A curvilinear edge is formed at the abutment of the first, second and third surface portions. Dependent upon where the surface of the ball strikes the playing surface, the ball bounces irregularly. To enhance the irregularity of the play, the second and third surfaces are surfaces of two semi-spherical domes and each semi-spherical dome has a hollow core region.
