Abstract: A hockey stick is provided with an offset or bend angular to the plane of the face of the blade and positioned to begin substantially at the location where the transition from the heel of the stick to the shaft becomes approximately equal to the cross section of the shaft in its parallel plane. In a preferred form a second bend then makes a rapid transition to the full offset configuration within the dimension of the shaft such that the blade portion trails the plane of the center line axis of the shaft and due to centrifugal force the trailing blade tends to rotate closed thereby cupping the puck by the blade results in reduced deflection and easier pass reception. According to the preferred embodiments, the offset is positioned where it can be located closest to the blade and in the parallel offset form the completion of the offset to its full off-set dimension takes place dimensionally as is possible within a unitary stick construction of a blade with shaft receiving handle portion.
