Abstract
Abstract A hockey stick is made as a unitary, injection molded product from foamed nylon mixed with glass fibre. The use of foamed nylon results in a relatively lense shell on surface and a core having reduced density. There are no cavities in the stick such as in known hockey sticks or the like made of plastic material. The stick maintains its shape after molding due to a relatively low stress caused by molding pressure which is low in comparison with that required in the production of known plastic hockey sticks. The stick is generally identical to a regular wooden stick from the standpoint of weight and that of weight distribution. An embodiment of the stick with aluminum reinforcement of its blade portion is also disclosed.
