This Brunswick Knock Out Black and Blue Bowling Ball 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 Brunswick Knock Out Black and Blue bowling ball will be another must-have motion in the bag.

Gebharts spent a lot of time with me for getting the right fit. And, the ball feels incredible in my hand. Boy, let me tell you, this ball is unbelievable. Just so smooth and continuous. This should be your benchmark ball. I have lots of confidence when throwing this ball because the reaction is that good!
