Our HSS inlaid knives contain 18% tungsten (SKH-2) at RC 62-63 which is designed to improve blade life as much as five times that of our AKI-I quality. This “high-tech” alloy is designed to be used under high production applications, to ensure an increased number of cuts between sharpenings, thereby reducing cost per cutting hour.
