Diamond Sharpening Stones Set 6x1” – Edge Pro Diamond Matrix | Free Shipping

The Edge Pro Diamond Matrix stones are high-performance sharpening stones engineered for demanding users. Designed to fit all Hapstone systems and other Edge Pro format sharpeners, these stones provide consistent, reliable results across a wide range of steels, including high-carbide alloys.


Precision-Crafted Performance

Each stone features a durable organic bond and evenly distributed diamond abrasive, offering fast material removal, controlled feedback, and extended working life.



HOW OUR RESIN BOND DIAMOND MATRIX STONES ARE MADE

Our diamond knife sharpeners start with precision CNC machined aluminum blanks that are machined super flat to minimize bow & twist.

Domestically sourced diamonds are evenly mixed throughout the resin while curing* onto the aluminum blank.

This reduces variation in thickness and provides the most consistent shape and performance during sharpening.



Ready to Use, Easy to Maintain

The stones are non-porous and require only a splash of water to begin sharpening. For maintenance, they can be cleaned with ethyl alcohol or silicon carbide powder on a flat glass plate.
