Duncan World-Class (1990)
Exhibit #2162
ShapeH Shape
OwnerRick Brough

An unusual Duncan made for a short time from 1979 to 1982. It was supposedly reproduced about 1990 using the exact same molds, but it was more likely leftover new, old stock from the early eighties. The yo-yo was unusual because it was a significant design departure from the traditional line of plastic yo-yos that had Duncan made and sold for more than 20 years (at that time in 1979). The profile of this yo-yo, combined with the use of separate, metal rim-weighting "inertia rings", was quite 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 own thermal bonded fluorocarbon resin (read: plastic) coating applied to metal axles. The coating reduced friction between the axle and string, and allowed up to 20% longer spin times. Reslon axles were used on Duncan's entire product line of yo-yos from 1979 to 1982, excluding the Junior model. The Reslon trademark, owned by Flambeau at the time, was cancelled December 15, 2000.

The 1979 version of this yo-yo 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. The 1990s version seen in this exhibit came in a simple, clear plastic box with no branding.

This same model of yo-yo was used by professional Duncan demonstrator George Humphreys on the cover of The Amazing Yo-Yo by Ross R. Olney from 1980.

Charles A. Lanius of Wisconsin, who also holds numerous invention patents and who worked for Flambeau Corporation, was the designer behind the Duncan "World-Class" yo-yo. The yo-yo, however, did not receive any patents.

Original retail price: $15 US.
