Sponsors and Curators The Museum of Yo-Yo History is a labor of love, and we would not be able to stay up-to-date with exhibits without the support of our sponsors and curators. Big thanks go to One Drop Design and Duncan for supplying us with their latest models, YoYoExpert for their help and support, and to Cody Orr, TotalArtist and YoYoBrothers™ for allowing us to use their collections! If you're a manufacturer, or just a big collector and you want to help support the Museum drop me at line at chimera@yoyomuseum.com Tomy Screw Ball Exhibit #1818 Type Production Shape Standard (-) Axle Transaxle - Plastic Packaging Bubble Carded Construction Multi-piece plastic Response Starburst Condition Mint in Package Date 1997 Owner Rick Brough Compare The Screw Ball yo-yo was made in Australia by Abbe Toys but was sold only in Japan under the Tomy brand name. When rotation slowed to a certain rpm, a built-in automatic clutch was engaged, returning the yo-yo to the player's hand. Functionality-wise it is just like a Yomega Brain, the original auto returning yo-yo. Tomy also released the Screw Ball Mini, also seen in this museum. Other Views Back 2005-2025 Software © David W.
