This ultra fine grit stone is triangular for sharpening plain edges on the flat sides and serrations on the corners. A furrow running the length of each stone lets you sharpen pointed items like fishhooks, darts and awls. Ultrafine stones tighten the blade's scratch pattern to an even keener degree for hair-popping professional sharpness and polishing.
TriAngle stones are 7"x.5" (178mm x 13mm). Sold Individually.
This item is designed for use with the Spyderco Triangle Sharpmaker.
