A hockey stick blade for roller or street hockey has a toe end, a heel end, top and bottom edges, a set of identical ball bearings, a set of identical sockets, at least one opening, and a shaft portion. Each socket is comprised of two identical truncated four-sided pyramids joined along their respective base edges. Each ball bearing is captured by one of each identical sockets and is mounted at the bottom of the hockey stick blade. The opening is positioned above each of the identical ball bearings, and allows for the unencumbered rotation of each of the ball bearings through 360 degrees in every direction. The shaft portion is adapted for fitment on the handle of a hockey stick. The opening in the hockey stick blade may be one of a series of slots positioned above each ball bearing or an elongated slot that extends from the first to the last ball bearings. The bottom edge of the hockey stick blade is split into two portions to allow the mounting of each of the bearing and socket pairs.
