Black Mamba: Starburst
The original Black Mamba line version of the yo-yo featured a starburst response system, and the PhatYo version released in the early 2000s featured the Cookie response pad system.
How the cam works
The centrifugal cam consists of three-armed deltas on each side of the yo-yo connected to the spacers. Each arm on the deltas has a small metal ball in it for added weight. When the yo-yo is thrown down, the deltas in each body half to move in an outward direction, allowing the yo-yo to spin freely. When it slows down, the deltas move inward, causing the spacers to pinch the string, and making the yo-yo return to the user's hand.
