It was originally sold under the Auldey brand and then Hasbro licensed it. The yo-yo stands out for its very easily modifiable configuration as either wing or tournament shape. It took a Tom Kuhn staple for many years and bumped it to the next level. Very unique design. (It was also just awarded a US patent!)
