Curved Venev Bonded Diamonds are used for sharpening inwardly curved blades on Hapstone and KME 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.

FAQ

  • Why curved diamonds don't utilize organic bonding similar to other Venev diamonds?

    The primary purpose of curved diamonds is precise honing at inside of pipe. The organic bonding technology is not suitable for this task.

  • Venev 2000 grit diamond creates large grooves on the cutting edge. What is wrong with it?

    This is completely normal for diamond sharpening, especially on high carbon steels. Diamonds offer high performance, sacrificing cutting edge quality. If you need a very accurate cutting edge, you should switch to non-diamond abrasives.

  • The max grit of Venev diamonds is 2000. What grit is good as a next step?

    The first thing to consider while combining stones from different brands is grit scale. Venev 2000 grit diamonds use 1 micron particles . In term of grit, Venev 2000 is an ultra-fine finish (approximately 15K waterstone grit).

  • What grit scale is used for Venev diamonds?

    Curved diamonds are marked with FEPA-F, JIS and national standard GOST 9206 (in micron) on the reverse side. FEPA-F is used to choose a desired grit when purchasing. F 2000 grit diamond is marked "1/0-F2000-J15000").
