An improved yo-yo, having a first yo having a first inwardly facing surface; a second yo having a second inwardly facing surface, the second yo arranged in spaced apart relation to the first yo, where the first and second inwardly facing surfaces face one another; an axle secured to and arranged between the first yo and the second yo, where the first and second yos are arranged for rotation about an imaginary axis coincident with the axle; and, a first fibrous pad secured to the first inwardly facing surface. Another embodiment comprises an improved yo-yo, having a first yo having a first inwardly facing surface; a second yo having a second inwardly facing surface, the second yo arranged in spaced apart relation to the first yo, creating a gap having a length between the first and second inwardly facing surfaces; an axle having a first end and a second end, the first end adjustably secured within a partial through-bore in the first yo, the second end fixedly secured within a partial through-bore in the second yo, where the first and second yos are arranged for rotation about an imaginary axis coincident with the axle; and, a ratchet assembly mounted to the axle and operatively arranged to change the length of the gap in response to rotation of the first yo relative to the second yo.
