Spyderco Profile Stone CBN Features The Spyderco Profile Stone CBN is built from a steel embryo coated with particles of 400-mesh Cubic Boron Nitride a super abrasive material that removes steel far more aggressively than typical sharpening stones. This aggressive cutting action makes the stone ideal for reprofiling edges that have been damaged or need a significant angle change as well as serving as a first step when sharpening very dull cutting tools. Because CBN sits second in hardness only to diamond the stone maintains its cutting ability over a long service life without needing frequent replacement. The 8 inch length provides a generous sharpening surface reducing the number of strokes needed to work along a longer blade. A suede pouch comes included with the stone protecting its abrasive surface from contamination and damage when not in use. This pouch also makes the stone easy to carry in a kit bag or tackle box alongside other sharpening tools. Because this stone is designed for aggressive material removal it pairs well with a finer finishing stone to complete a full sharpening progression. This Spyderco Profile Stone CBN is available for sale at GrabAGun for hunters outdoorsmen and knife enthusiasts who need to restore a seriously dull or damaged edge.
