The Gatco 16001 Diamond Coarse Sharpening Hone is engineered for rapid edge restoration on extremely dull or neglected knives where aggressive material removal is required. The coarse diamond abrasive surface cuts significantly faster than traditional stones, allowing damaged or rolled edges to be reshaped efficiently while maintaining consistent bevel geometry. Diamond construction eliminates the need for honing oil, reducing mess and simplifying maintenance while delivering reliable, repeatable cutting action across hardened kitchen, sport, and utility blades.Designed for full compatibility with all Gatco guided sharpening systems, the hone works in conjunction with fixed-angle knife clamps to maintain precise sharpening angles during heavy edge correction. The rigid diamond surface resists wear and loading, ensuring consistent performance through repeated use. This hone serves as an essential first step in a complete sharpening progression, preparing severely worn edges for subsequent medium and fine honing stages to achieve a clean, service-ready cutting edge with improved sharpness and longevity.
