Brunswick Knock Out Black & Blue Bowling Ball

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.

HIGH: Top performing balls offering great hook potential on a wide range of conditions.

ALL PURPOSE: Versatile ball motion that is useful across various lane conditions, usually a continuous and strong arcing ball. Balls with higher numbers will have stronger overall reactions.

REACTION SHAPE STRENGTH: 81 - The higher the number the stronger the reaction shape – with 1 being the least and 100 the most.

The Knock Out Black and Blue features Brunswick’s innovative outer core technology called DynamiCore. This industry-leading technology is a more durable outer material that yields less compression upon impact increasing hitting power and creating an undeniable difference in sound and pin carry.
