Hammer will be introducing one additional product at Bowl Expo this season. Hammer will
have a high-performance release called Jigsaw. This ball starts off a new high-performance price
point series for Hammer, and brings our brand to a new level of performance on the lanes.
Jigsaw starts out with a brand new core for Hammer. We started building Jigsaw with a low rg,
high differential core system. But we didn’t stop there. Our R&D team removed a critical piece
of the puzzle from the core, and created an extremely high mass-bias wedge in the core shape.
The result is the highest mass-bias ball in the history of Hammer! High mass-bias core shapes
give the bowler more backend reaction and continuation without loss of energy, and the Jigsaw
certainly delivers that!
We’ve also developed a new coverstock for our Jigsaw release. Our new Gription Reactive 5/4
Coverstock is unique in two ways. First, this coverstock is a breakthrough for us in length and
backend combination. Our mad scientists have developed this coverstock to push through the
front of the lane cleaner than any sanded ball in our line. But the midlane and backend is where
this coverstock pairs up with the core system, and takes control. Jigsaw rolls heavy through the
midlane and doesn’t stop in the backend. This is truly a unique ball reaction that we simply have
not seen before. The Jigsaw comes in a never-used, Black and White color with Orange logos.
There’s no doubt that bowlers will know exactly what ball is being thrown when they see this
high-performance product going down the lane.
Finally, our new coverstock finishing process has been applied to the Jigsaw to create a unique
ball motion. Our new 500/4000 process gives the Gription Reactive 5/4 coverstock the ability to
skid through the front part of the lane without early hook. But the 500 grit under-surface gives
Jigsaw’s Gription Reactive 5/4 coverstock the teeth to cut through the downlane oil, giving this
ball the most backend reaction in the history of Hammer products! Jigsaw is a new breakthrough
for Hammer in bowling ball motion.
