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.
