The Buzine$$ (also known as the Biz for short) is a yo-yo from Anti-Yo and is Brian Cosky's signature yo-yo, released on Martin Luther King Day in 2007. It is smaller than your average yo-yo, with a profile that is said to have possibly come from the Duncan Mosquito. It also features the usual low-friction Slip Matte finish, a KonKave bearing, and Kentaro Pad response. Its production run is limited to 450 pieces.
