ABSTRACT:
A yo-yo having unique tether engagement areas adjacent the axle. The engagement areas include an array of grooves and/or rubber pads located in the tether-facing surface of each of the yo-yo's side pieces. The grooves and/or pads extend from a point proximate the axle to a point significantly spaced from the axle. In the preferred embodiment, the grooves and/or pads are employed in conjunction with an axle having a ball bearing-supported rotatable outer race to which an end loop of the tether is secured.
