Spyderco Profile Stone CBN w/Pouch – Precision Diamond Sharpening System

The Spyderco Profile Stone CBN is a specialized sharpening stone designed for maintaining edge geometry on curved and profiled blade grinds. Using cubic boron nitride (CBN) abrasive—second only to diamond in hardness—this stone excels at sharpening high-alloy and powdered-metallurgy steels that resist conventional stones. The profiled shape lets you match the stone to convex edges, recurves, and scandi grinds without flattening or altering the blade's original geometry.

CBN abrasive cuts faster and stays flatter than aluminum oxide stones, making it ideal for touch-ups in the field or systematic maintenance at the bench. The stone comes with a protective pouch for safe storage and transport. Compatible with most sharpening systems or usable freehand, it's a reliable choice for hunters, bushcrafters, and knife enthusiasts who demand precision edge maintenance on demanding blade steels.
