Smith's 8" Diamond Tri-Hone offers comes with two interrupted surface diamond stones and a medium Arkansas stone. The coarse and fine-grit diamond stones feature a unique, overlapping hole design that speeds sharpening by collecting and holding the metal filings which build up during the sharpening process, thus allowing the stone's surface to remain clean and clear. The Natural Arkansas Stone is best used for finishing your edge and removes moderate amounts of metal as it polishes the cutting edge. 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. This 3-stone sharpening system is excellent for sharpening pocket knives, hunting & fishing knives, kitchen knives, single bevels, and tools of all sizes, large or small. It 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.
