Long Description
Perfect for rebuilding worn‑down, neglected cutting edges, our 400# resin diamond sharpening stone sits between heavy repair and fine sharpening. It efficiently shapes blade geometry after coarse‑grit repair work, removing scratches left by extra‑coarse stones and setting the foundation for subsequent sharpening steps.
The standard 1″×6″ flat profile delivers stable honing performance and is fully compatible with mainstream guided sharpening jigs. Made of premium resin‑bonded diamond abrasive, it maintains flatness far better than conventional water stones. You get predictable, repeatable shaping results without frequent truing or replacement.
Well‑suited for kitchen knives, hunting blades and outdoor tools that need edge reshaping. Ideal for beginner sharpeners and professional users doing intermediate‑stage blade restoration.
For best performance and extended lifespan, store the sharpening stone in a dry, clean environment after each use to avoid moisture erosion and abrasive particle aging.
