Abstract
A yo-yo includes a first yo-yo half defining a first starburst, a second yo-yo half defining a second starburst, and an axle fixedly mounted between said yo-yo halves. The yo-yo also includes a roller bearing fixedly attached to the axle, and a spool fixedly attached to the roller bearing, the spool having a circumferential outer rim with a groove therein. A bearing pocket defines an annular radial gap between each yo-yo half and the outer rim, the gap sufficiently small that a string cannot wedge in the gap.
