The Duncan Butterfly yo-yo, first released in the 1950's, made it easier for people to land and perform more complex string tricks with its wide inward-tapered shape and rim concentrated weight. Not long after the Duncan Imperial yoyo, came the Duncan Butterfly. So classic is this yoyo, that "butterfly" has become the term to describe yoyos that have an open shape making string tricks much easier to perform. The Duncan Butterfly Yo-Yo is a fixed metal axle yo-yo built in the traditional Duncan style.
