Jigsaw Core

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!
