Abstract: A field hockey stick including a head, a shaft adjoining the head, and a vibration damper. The shaft has a first end proximate the head and a second end opposite the first end. The vibration damper is disposed in the second end of the shaft and includes a core and a jacket surrounding the core. The material of the core has a higher specific gravity than the material of the jacket.

Abstract: An apparatus and method for determining compliance of a lacrosse stick head with dimensional specifications that require a minimum allowable width between the two sidewalls of the head as measured at a designated distance from the stop member of the head. The apparatus has a width equal to the minimum allowable width of the lacrosse stick head, and a length perpendicular to the width. The length is equal to the designated distance. The apparatus is adapted to simultaneously measure the designated distance and the minimum allowable width. In a specific implementation, the apparatus has an upper rectangular portion connected to a lower triangular portion.
