Gatco Coarse Replacement Diamond Hone GAT16001

The Gatco Coarse Replacement Diamond Hone is built for the heavy work — the fast metal-removal stage that sets the foundation for every proper edge. Designed as a direct replacement for any Gatco Knife Sharpening System, this hone locks right into your existing guide rod setup and immediately restores full coarse-cutting capability with no modification required. If your original stone has glazed-out or slowed down over time, this is the part that brings your system back to factory aggression.

Its industrial-grade diamond abrasive is bonded to a precision-ground substrate, delivering a consistent, aggressive cut that won’t dish, wear unevenly, or load up like traditional stone media. Coarse grit is where your geometry correction happens — fixing rolled edges, repairing chips, reprofiling stubborn stainless, or thinning a work-worn bevel before progressing to finer hones. This replacement hone does that work fast and predictably, giving you a crisp apex base that makes the polishing stages both faster and cleaner.

The orange handle isn’t just a color choice — it’s an at-a-glance grit indicator, exactly in line with Gatco’s intuitive sharpening system logic. It’s shaped for a steady, confident grip even with oily hands or in cold-weather conditions, and it’s tough enough to handle shop, field, or duty use without deforming or cracking. From bushcraft blades to modern powdered steels, to serrated rescue tools or compact EDCs, this hone is built to bite into metal and get the edge back under control before you begin refining.

Like all genuine Gatco components, this hone is purpose-built, not generic. It interfaces cleanly with the angle guide to keep your factory or custom bevel consistent — no guessing, no jitter, no wasted steel. Whether you’re restoring performance to an everyday carry or rebuilding a tool that’s seen abuse, this coarse diamond hone is the first step in taking a blade from dull to dangerous.
