Abstract: A custom grip may be molded on a handle. Examples of handles that may benefit from a custom grip include baseball bats, hockey sticks, pool sticks, lacrosse sticks, tennis racquets, golf clubs and the like. The molding of the grip may be a combined synergy of thermal energy resulting from friction and electrical current flowing through a material that hardens in response to both thermal and electrical stimulus. This hardening process may occur while undergoing the dynamics that the end product experiences when in use by the intended user. The resulting handle may be both uniquely matched to the user's hands as well as his or her style of use.
