Smith's 6" Diamond Tri-Hone is perfect for sharpening pocket knives, hunting and fishing knives, kitchen knives, and cutting tools of all sizes, large and small. It features two interrupted surface diamond sharpening stones with a unique Micro-Tool Sharpening Pad and a Natural Arkansas stone for finishing and polishing the cutting edge. The 6" x 1 5/8" color-coded and labeled stones include a coarse diamond stone (325 grit), a fine diamond stone (750 grit), and a Natural Arkansas stone (1000-1200 grit). All three stones are mounted on a triangular-shaped base with handles on the end for easy stone rotation and feature easy-to-identify stone labels. The stones are held in place by a sturdy, non-skid stand with a trough in the bottom to catch any excess honing solution. The stone sharpening system also includes a sharpening guide for proper sharpening, care instructions, and a 1 oz bottle of premium honing solution to clean and protect against damage.
