Spyderco's ProFile Stones are compact, portable sharpeners that quickly restore the edge or point on nearly any tool. Their innovative design features multiple abrasive surfaces and shapes, allowing them to efficiently sharpen a variety of knives, including those with plain or serrated edges. The carefully radiused convex surfaces are tailored for sharpening gouges and woodworking tools, while the longitudinal grooves handle awls, scribes and other pointed instruments with ease. These advanced abrasives require no oil or water, making them exceptionally convenient. Available individually or in a set of three, each stone comes with a protective suede pouch that also functions as a non-slip pad during use. Made from gray alumina ceramic with a medium grit of approximately 600, this stone is perfect for most sharpening tasks, offering fast steel removal and a sharp, utility-ready edge.
