The Redline is an inexpensive wooden yo-yo with a ball bearing axle and Turbo Disc response, designed to sell for around $10 USD. The standard design is a depiction of a speedometer on a black and silver painted yo-yo. Also released was a special red and black version of the Redline, the "Wood Rocks" or "Brush & Yo Daily" yo-yo, the latter of which celebrated 35 years of Dr. Kuhn's dentist career.
