- Description: 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 Burst 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 Burst 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 Burst 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.

When I have some oil on the lanes, the Jigsaw is THE best ball I have seen since the Forest Green Quantum. A few weeks ago it gave me at 300 with a 762 series.

where should i start  i drill it label down and in player 10th board  and must say that this ball sucks  it hits very hard dont get me wrong i had at out of the box -- brutal reaction  just plain 4000 grit--- no reaction until its too late and had it 2000 ----a little better but hit like a piece of crap  when i needed to strike the most so out of 10 overall rating is a 6  and i am being nice  about to sell the damn ball if no improvement only bright spot is carries light hits very well but cant depend on that to score we all know that  i hate the color too i do better with dark color balls dont know why

Style: Power player
Speed: 16.5-17.0 mph (down lane)
Rav Rate: 450-480
Axis tilt: very little
Axis rotation: 35-40 degrees

Layout (dual angle): 65 X 6 X 40, no extra hole

What I was looking for in this layout was to get the ball cleaner through the front part of the lane and give me a good pop on the backend without being too wild. 1st day i threw this ball, i got just what i was looking for, i was very impressed with the motion, but not how it was inconsistent in reading the midlane. Took the surface down to 2000 and it was a whole new ball! it read the lane exactly where i wanted it and this thing HITS LIKE A HAMMER!! The jigsaw is a flat out tank. i can move just about as far left as i want and this ball comes back every time, yet i can move right, keep some speed on the ball, and it takes the dry part of the lane pretty well.

Overall, i would say this ball is great for a heavy volume of oil, and still punches pretty good on the medium stuff. if your looking for a ball that eats the heavy oil up and doesnt quit, buy the jigsaw.

Purchased this ball about 3 weeks ago, placed the pin at 12:00. At first  I rolled it at 4000 oob 1st game was a 225, next two games ball seemed inconsistent then I sanded it to 800 with a little polish and BOY !!!
the next week I shot a 808 series then in another league I shot a 719 series. This ball is a keeper!!!! last Sunday i noticed all my friends purchased Jigsaws 3 to be exact....Coincidence I don't think so

Purchased my 15lb Jigsaw about 3 months ago. Soon after I posted my highest game ever with a 286 back in January. Then last night (3-4-10) posted my first 300 game after 30 years of bowling. This ball is the real deal. Still won't correct my own faults but as long as I let the ball do the work it hits like a bomb. Way to go Hammer. You are really onto something with the 5/4 finish. I usually face medium oil at best and this ball clears the heads better than anything I have ever thrown and it also carries more energy to the pocket than I have ever seen. Thanks Hammer!!!

I waited until the end of the year to share this.  Ball was recommended and drilled by Center Lanes Pro Shop in Philly earlier this year and has paid for itself 10 times over.  Shot 300 in March followed by back to back 299's 2 months ago (not to mention the numerous 270+ games)!  Ball is awesome on tight and running lanes, all depends on your release.  Heck, I'm left handed and can make a 7-pin with it.  Versatile ball with great carry!
