169H Large 8" x 3" Dual-Grit Diamond Sharpening Stone – Extra-Coarse 220 & Fine 600 Grit Monocrystalline Diamond Whetstone, Professional Knife Sharpener with Anti-Slip Pad and Angle Guide

:whetstones, diamond sharpening plates stay flat, require no lapping, work dry without mess, and deliver more efficient, consistent results. Extra-coarse 220 grit (60 micron) restores severely damaged edges; fine 600 grit (25 micron) refines and enhances sharpness—delivering fast, efficient profiling and sharpening in one stone. The 8" x 3" (200 mm x 75 mm) size offers greater stability, better angle control, and supports larger tools—ensuring faster, more precise sharpening. Exhibits superior structural integrity and fracture toughness, ensuring long-lasting performance and consistent sharpening under heavy sharpening pressure. The advanced Three-Times Electroplating Process firmly anchors diamond particles and precisely controls abrasive exposure—ensuring long-lasting, consistently sharp cutting surfaces. MirrorFlat technology with precision-ground flatness (±0.002 inch / 0.05 mm) ensures even blade contact for accurate edge geometry and consistent sharpening results. Comes with a 4-angle guide (14°, 17°, 20°, 25°) to maintain consistent edge geometry for optimal blade performance, and a non-slip pad to ensure safe, stable sharpening while protecting your work surface. Headquartered in California, USA, with branches in Germany and Australia, provides easy and effective sharpening solutions. All products undergo rigorous testing to ensure top-tier performance and durability. Diamond sharpens even the hardest steels, including super steels like CPM-series, M390, and Elmax.
