The Twin Twirler, made by Kusan in the 50’s and 60’s, was a yo-yo top combo. From what I’ve heard, the Twin Twirler was only sold in Chattanooga, TN (with the exception of the Kusan World Yo-Yo Contest in NYC)… Of course I found that out about a month after moving from Chattanooga to ST. Louis. I wish I would have known that I should have looked for Twin Twirlers while I was living there.
Bob Baab was a Kusan demonstrator in the 60’s. During a phone conversation with Bob in November of 2000, he described how he and fellow Kusan demonstrator Dale Oliver used to demonstrate the Twin Twirler. Bob said that they would wind up their yo-yo using the same offstring winding technique we use now, then they would throw their yo-yos sideways (parallel to the ground) and they would spin freely on the ground like a top.
Bob went on to describe a method of getting the yo-yo back on the string and wound back up to the hand by sliding the yo-yo string into the gap, wrapping it around axle, and pulling. Baab was pretty much describing the beginnings of offstring yo-yoing. Throughout the years, Dale continued this offstring winding technique, but he started throwing the yo-yo from a forward pass and catching it on the string. It would take about 30 years though before Jon Gates would find a method of making an offstring yo-yo return to the hand.
