The invention is a yo-yo that employs an active starburst tether engagement system located in one or both of the yo-yo's side members (2). The system makes use of a starburst-shaped array of movable engagement ribs (58) that face the tether (6) and are located near the yo-yo's axle structure (4). Each rib is independently movable and is located at the end of a flexible finger (64) that enables the rib to be moved by the tether in a direction substantially parallel to the yo-yo's axis of rotation. |
