Adding to cart… The item has been added

The Katana Assault has an RG of 2.501, a differential of 0.051, and an intermediate differential of 0.020. This core yields a quick response to friction and a lot of continuation through the pins. The Katana Assault and the new chemical compound cover known as HK22 Pearl create a new level of backend reaction. This is a Katana on steroids. A monster flip ball, a motion the industry has always craved and now we have brought it to a whole new level.

    Katana Assault

    Posted by Carolea Oakes on Mar 18th 2023

    I went with a 40x4x30 drilling. My speed is 14.5 and low rev rate. The original Katana has always been one of my all time favorite balls so I was very excited for this one.This ball is very clean, gets down lane longer before making that monster hook into the pins continuing through the deck. I use this ball on medium oil lane conditions and see very little transition only needing to move 3 to 4 boards over a 3 game period.

    Favorite core with favorite cover

    I loved my original Katana. Now with the new HK22 cover, it is back, and better than ever. Being a Hybrid, it fills a gap between my Top Speed and my Black Widow Ghost. This ball fits perfectly in my arsenal.

    Assault the Pins!

    Posted by Clancy DeGroodt on Jan 13th 2023

    Once again putting the HK22 Pearl cover on a Radical piece has raised the bar in expectations. I drilled mine pin down as I wanted to add an asymmetrical pearl to my pin down bag. I have only had the control given by the pin down layout in the Max Results. This ball is exactly as expected smooth and strong through the pins. The HK22 cover gives that special punch on the back and carries the slight misses much like the Bigfooot Hybrid. Love this one and I will be getting another for a pin up layout!
