An unusual Duncan made for a short time in the very early 1980s, then reproduced about 1990 using the exact same molds. It's unusual because it was a significant design departure from the traditional line of plastic yo-yos that Duncan made and sold for more than 20 years (at that time in 1980). The profile of this yo-yo, combined with the use of separate, metal rim-weighting "inertia rings", was very unique and about 20 years ahead of its time.

The metal axle on this model is Reslon-coated. Some people refer to this coating as Teflon, but that is incorrect. Reslon was Duncan's very own thermal bonded fluorocarbon resin coating that was applied to metal yo-yo axles. The coating reduced friction between the axle and string, and allowed up to 20% longer spin times (remember, this was about ten years before the release of Tom Kuhn's uber famous Turbo Yo/Silver Bullet 2 that used a ball bearing axle). Reslon axles were also used on Duncan Imperials, Professionals, and Butterflies in the early 1980s. The Reslon trademark, owned by Flambeau at the time, was cancelled December 15, 2000.

The early 1980s version of this yo-yo, as seen in this exhibit, came beautifully boxed, and included a 48-page Duncan Yo-Yolympics trick book. It also came with a personal "World Class" ID number that you could register by mail with both Duncan Toys and Duncan's "Yo-Yo Players International" group.

This same model of yo-yo was used on the cover of "The Amazing Yo-Yo" by Ross R. Olney from 1980. Charles A. Lanius of Wisconsin worked for Flambeau Corporation and was the designer behind the Duncan "World Class" yo-yo. While he held numerous invention patents of his own, the World Class yo-yo did not receive any patents.
