Katana Slash
on: March 07, 2018, 05:20:23 PM
Ball NPS Score: 100.00
The Radical Katana was named after a Japanese sword that has a curved single edged blade with a long grip. The Radical Katana Slash continues this tradition with increased angularity. This ball has the same core as the original Katana but the Forged 2 coverstock is stronger and more aggressive. This ball is a backend monster when facing heavy oil conditions. The Katana Slash not only offers awesome performance but lots of backend reaction on heavy oil as well.

Color: Dark Red Pearl/Light Red Solid
Core: Katana Asymmetric
Coverstock: Forged 2
Finish: 500, 1000 Siaair/Crown Factory Compound
RG: 2.503**
Differential: 0.050**
** RG and Diff are based off of 15 lb. balls
Recommended Lane Condition: Heavy Oil

Radical Katana Slash,
Im left hander. Ball speed around 15 mph. Rev rate around 275-300. It was recommended to get two of these balls. One with a short pin layout another with a long pin layout. The layouts are 120 x 1 1/2 x 60. The other layout is 50 x 4 1/2 x 40 with a P3 balance hole. By doing the two different layouts I have two different backend motion. The short pin layout allows me to play straighter up the boards. And the other allows me move deeper inside swing it. Now these balls arent for the light volume oil patterns. But this setup works great together. There is about 9 boards hook differences between the two. I think Radical Bowling Technologies did a great job designing this ball.

Ball Weight: 15 lbs


Dual Angle: 50 x 4 3/4 x 60

X Hole (if there is one): No


Rev Rate: Medium , between 250-275 rpm

Ball Speed: 17-18 mph

PAP/Track: 5 1/2" over and 1/2" down


Grit: Box Finish

Type: (Matte, Polish, Sanded): Polished

The Katana Slash is the most versatile ball I have ever thrown.  Its cleaner than the original Katana through the front but reads the midlane a lot quicker and has a more angular continuous on the backend.  I laid mine out for a cleaner skid through the front and more downlane motion.  The Katana Slash is a homerun ball
