Abstract
A hockey stick apparatus may include a molded blade structure coupled to the proximal end of a hollow shaft structure. The molded blade structure can include: a top edge spaced apart from a bottom edge by a blade height, a heel spaced apart from a toe by a blade length, a front face spaced apart from a back face, and an optional slot defining an aperture extending through front face and the back face. A stiffness of the blade may vary along the blade height by changing the shape of the blade and changing a quadratic momentum of the cross-section along the blade height.
