This Knife Is 10x HARDER Than Steel?!

Why would a knife need diamond abrasives to restore its edge? Sandrin knives use tungsten carbide with a manufacturer-rated hardness of 71 HRC. Their unusual material combines extreme wear resistance with a formulation designed to address carbide’s traditional brittleness. Discover the engineering behind this extraordinary blade, why its hardness makes sharpening challenging, and how it differs from ordinary steel knives.
