Venev Gemini Series Curved Diamond for Edge Pro

  Edge Pro form-factor stones are suitable for Edge Pro, Hapstone, TSProf and all Edge Pro compatible sharpeners




Curved Venev Bonded Diamonds are used for sharpening inwardly curved blades on Hapstone knife sharpeners. Diamond sharpening stones offer excellent performance in sharpening knives of any steel. The working surface is curved. Curved diamonds are designed to sharpen kukris, karambits, hawkbills, scythes and any type of recurved blades.

Curved Diamonds consist of a 2 mm-thick diamond-bearing layer on a metal base. The diamond-bearing layer contains evenly distributed diamond grains with metal bonding. Metal bonding gives the sharpening diamond stone a long lifespan.

How to use

Venev Diamonds are recommended to be used with water as lubricant for the best feedback. The diamond does not absorb water. Splash water on the stone's surface. Dry usage is acceptable practice.

Venev Diamonds may have the geometry tolerance up to 0.2 mm. Because diamonds are curved, extra lapping by a customer is not permitted.
