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!

The 401k represented another major innovation in yo-yo technology, as we've come to expect from the Van Dan Elzens. Hans and his team at YoYoFactory created the first yo-yo with an adjustable response system. Shuttles around the bearing move in or out, depending on how you adjust the knob on the outside of the yo-yo. So response can be increased or reduced, depending on how you advance or retract the shuttles.

While the 401k came with starburst response, stickers could be also used, making this a very flexible design. Look carefully at the shuttle around the bearing, and adjustment knob on the outside.
