The Hammer Special Effect is the ultimate evolution of the iconic Effect, one of Hammer’s most successful high-performance balls in years. Featuring the powerful Huntsman core from the original Effect, this ball takes performance to the next level with the HK22-Cohesion Solid coverstock—one of the most dynamic covers in bowling. Finished with factory compound, the Special Effect delivers outstanding mid-lane motion and a bold, aggressive backend reaction. Compared to its predecessor, it offers the same effortless length but reads the lane slightly earlier, making it a game-changer when extra hook is needed on oily conditions. Built for versatility, the Special Effect is a must-have for bowlers looking for a strong, consistent reaction across various oil patterns.
