Abstract
A hand-held implement grip and protectant, preferably for a hockey stick, is described. The invention mainly consists of a blade attached to a composite shaft integrally enshrouded with a rubber sheath. A method of forming the same is also provided as laying up a number of sheets of composite material, wrapping those sheets about a mandril, enshrouding the layup with a rubber sheath, vulcanizing the combination, removing the mandril, and inserting a blade therein.
