Gatco Coarse Replacement Hone Sharpener Model 15003 GAT15003

The Gatco Coarse Replacement Hone Sharpener Model 15003 is built for the first and most critical stage of sharpening — fast steel removal and geometry correction. This coarse hone is designed to wake up completely dull edges and reset a damaged or fatigued bevel before any refining stages begin. It’s an essential working component, not a cosmetic add-on, and it brings worn sharpening systems right back to peak performance the moment you lock it in.

Constructed with high quality aluminum oxide, this stone delivers aggressive cutting action while maintaining the consistency and control that Gatco’s guided systems are known for. It doesn’t load up prematurely, doesn’t skate across stubborn alloys, and doesn’t require excessive pressure to start shaping an edge. Whether you’re dealing with a rolled EDC, a chipped hunting blade, or a kitchen knife that’s gone past the point of touching up, this hone is the tool that brings the edge back to life. It cuts fast — that’s what it was built to do — but it does it cleanly and with minimal metal waste.

Fully compatible with any Gatco sharpening system, Model 15003 snaps into your existing angle guide and immediately restores the cutting backbone of your kit. No retrofitting, no jury-rigging, no off-brand tolerance issues. If you own a guided Gatco setup, this hone is ready to slot right in and work as intended. It’s made in China under Gatco’s strict specification, built to the same exact profile and ergonomics you expect from the original parts.

The handle is shaped to give you a secure, fatigue-free grip even if you’re sharpening for extended sessions or working in cold or slick conditions. That grip stability matters — especially when you’re removing serious metal and setting your primary bevel depth. From there, finer stones can do their job quickly, because the coarse hone has already done the heavy lifting.

If your edges feel beyond the point of simple touch-ups, this is the component that restores control, authority, and reset-level sharpness to your sharpening process.
