Raptor
The Raptor has quickly become a favorite among Kvarnstrands customers. It’s simplicity and fast mounting of the corrugated knives make it unique in the marketplace. With only two screws, the breakdown and set-up times are greatly reduced compared to conventional cutters. It also allows for getting more knives into the head diameter vs. conventional head offerings. Having no screw holes on the periphery means less cleaning is necessary after running the head.
