ABSTRACT:
An ultra performance yo-yo having greatly improved spinning characteristics formed of two sections made of it least two materials, so that a substantial portion of the weight of each section is located about a periphery of the section thereby maximizing the rotational inertia of the yo-yo, and an axle assembly positioned between the two sections locating them in a spaced apart relationship. A string finger guard is used with the yo-yo string, and comprises a flexible sleeve having a longitudinal aperture, with a flexible leash slidably positioned in the longitudinal aperture. The yo-yo string is coupled to the leash, and the flexible sleeve protects the player's finger from pinching and discomfort.
