Spyderco Profile Stone Set, 3 Knife Sharpening Stones, 8 Long, Ceramic and Cubic Boron Nitride Construction, Includes Pouch 701MFCBN

Spyderco's ProFile Stones are convenient, carry-anywhere sharpeners that will put an edge or point on virtually any tool in no time. Their unique design provides multiple abrasive surfaces and shapes to efficiently sharpen knives with all different blade shapes and both plain and serrated edges. Their carefully radiused convex surfaces sharpen gouges and other woodworking tools, while their longitudinal grooves make quick work of awls, scribes, and other pointed tools. Even better, their advanced abrasives also do not require any oil or water during use.
