## Description

This Knock Out Black and Blue uses Savvy Hook 3.5 Solid, a slightly stronger cover and motion on the lane. In addition to the stronger cover, we’ve added sparkle to help it bite through oil, and it uses a stronger finishing process. The Knock Out series is also a perfect complement to the Melee Jab balls, as it uses the same core but a stronger cover and finish. The Knock Out Black and Blue will be another must-have motion in the bag.
