Diamond Matrix Stones
Upgrade your Edge Pro system with world-renowned Diamond Matrix stones — the gold standard in resin-bond diamond sharpening.
Built on a proven diamond/resin matrix developed over 20 years of production use, Diamond Matrix stones cover everything from fast stock removal to fine edge refinement on the same platform. They use only diamond — no fillers or secondary abrasives — with a performance-optimized diamond concentration for controlled, efficient cutting, especially on modern high-hardness steels.
Because the matrix doesn’t break down as you sharpen, the sharpening experience is cleaner than it is with the standard water stones. Each stone is molded onto a CNC-machined 6061-T6 aluminum backing to maintain flatness, stiffness, and accuracy under load.
Edge Pro Diamond Matrix Stones for Precision Sharpening
For precision work, Diamond Matrix stones give you a flat, stable cutting surface and a tight, repeatable scratch pattern. The resin-bond diamond matrix distributes abrasive evenly, so the stone feels controlled instead of grabby — which matters a lot when you’re sharpening modern, harder steels where small inconsistencies show up immediately.
Start with a coarse or medium stone to reset an edge, remove damage, or establish clean bevel geometry. Then step through the line grit by grit as the scratch pattern tightens and the edge comes alive. If you keep stepping up, you can push past a working edge to a mirror finish that looks as clean as it cuts. Many sharpeners consider these some of the best stones for Edge Pro-style systems because they cut extremely well and deliver a cleaner, more controlled sharpening experience from start to finish.
Maintenance stays simple. When the surface loads up, you can clean it with denatured alcohol, or refresh it with aluminum oxide powder and water on a flat plate of glass. That quick resurfacing helps expose new diamond abrasives and will make the stone cut more aggressively. Use silicon carbide when the grit calls for it, and you will keep the stone cutting the way it should.
These stones fit a bench workflow, whether you run an apex knife sharpener or other edge pro sharpeners. Build a knife sharpening kit around one sharpening stone at a time, then add complementary knife sharpening tools as your needs grow. If you compare knife sharpeners across systems, this lineup often hits that “perfect stone” sweet spot.
