Fiddle Stick
According to the original Japanese manufacturer, the toy was devised by a man named Toshio Sato in 1997. It was first exhibited at a toy show in Nuremberg, Germany in 2001. Formal production started at the Odawara Woodworking Factory in 2004. In 2015, Concell became the main sales outlet. It wasn’t until 2016 that a silicone rubber pad was placed on the ends of the Kururin to lessen the slipperiness and improve performance. While the original Kururin was constructed of a light-colored hardwood with dark walnut for the ends, it later changed to pure birch and then maple. In September of 2017, a new series was released using white ash, purple heart, and keyaki. The toy enjoyed great success in 2016 and 2017. The term “Kururin” is trademarked by Comcell Co., Ltd but it is not clear whether the design itself is in any way patented or protected. Today there are many look-alikes being sold under a variety of names (fidget stick, tumbling stick, desk walker, Jammer). It is mass-produced by toy factories in China and used for promotional gifts.
