The Inferno is a yo-yo produced by Abbe Toys as Dave Schulte's signature yo-yo. Since it is an auto-return yo-yo, featuring a four-armed cam system, it is great for beginners. It also has a ball bearing axle allowing it to sleep longer, so it is also good for an intermediate player. Under the side caps are an array of metal balls that add weight to the yo-yo. There were 4,416 Inferno yo-yos produced and sold between 2002 and 2004, and when the mold was lost, no more were made.
