An apparatus for attachment to a hockey stick shaft includes an elongated body having a first end, a second end and a longitudinal axis extending between the first end and the second end. A connector is provided at the second end for connecting the elongated body to a hockey stick shaft. There is a raised grip profile on the elongated body in an intermediate position between the first end and the second end. The raised grip profile defines a ring which encircles the elongated body. The ring is in an oblique angular orientation relative to longitudinal axis of the elongated body. The ring in an angular orientation fits between the thumb and index finger increasing strength and control when stick handling.
