This invention relates to a hockey stick comprised of a shaft and blade which simulates the principal characteristics of a wooden hockey stick including a blade in which a wear resistant core is provided wherein the areas subject to wear are exposed and areas subject to impact are covered with a resin or plastic, and further provided with apertures in non-impact areas to increase the striking area and simulate the weight and distribution characteristics of a wooden hockey stick. The core is comprised of two substantially vertical surfaces and a base portion. The base portion of the core extends horizontally beyond an imaginary extension of the substantially vertical surfaces.
