Abstract
A superior yo-yo toy exhibiting characteristics of a lengthened spinning time for performing tricks while retaining characteristic of returning to the hand of the operator when desired; and automatic return to the operator when the yo-yo rotational rate has slowed to a predetermined rate. The yo-yo string is attached to a free-spinning bearing surrounding the axle, the bearing operably connected to a centrifugal actuated spring loaded clutch mechanism so that when the yo-yo rotational rate slows to a pre-determined rate, the clutch mechanism engages the bearing, coupling the free-spinning bearing to the yo-yo and causing the yo-yo to return to the operator.
