ABSTRACT:
A bowling ball includes an inner weight block surrounded by the bowling ball shell. The weight block has a body, head and tip portions. The central x axis for the body is offset from the X axis of the ball, while the centered x axes for the head and tip portions are aligned with the X axis of the ball. A ball with such a construction exhibits increased torque which manifests itself as a sharp hook deep into the roll, while the initial trajectory is relatively straight.
