Venev Dual Side Diamonds are used for sharpening knives on Hapstone knife sharpeners. Diamond sharpening stones offer excellent performance in sharpening knives of any steel.
All diamonds consist of two 1 mm-thick diamond-bearing layers on the aluminum plate. The diamond-bearing layers contain evenly distributed diamond grains with organic bonding. The manufacture of bonded diamonds is more complex than for coated diamonds. Bonded diamonds give the sharpening stone a much longer lifespan.
The set includes 3 stones with total 6 grits: 80 + 150, 240 + 400, OCB 800 + OCB 1200 (FEPA-F).
Recently Gritomatic included OCB bonded diamonds 800 and 1200 grit to Venev product matrix. OCB binder offers extraordinary sharpening quality but it's not available in 2000 grit which was excluded from New Grit Matrix:
Old Grit Matrix is sold while stock lasts (100 + 240, 400 + 800, 1200 + 2000)
Venev Diamonds are recommended to be used with water as a lubricant for the best feedback. The diamond does not absorb water. Splash water on the stone's surface. Dry usage is an acceptable practice, although it results in faster wearing and speeds up stone loading.
Venev Diamonds may have the flatness tolerance up to 0.2 mm. Additional flattening and lapping can be performed by a customer to improve sharpening quality. We recommend using loose silicon carbide powder. Using a diamond lapping plate are not recommended.
Coated diamonds have all the diamond grains on the surface, maximizing performance. Bonded diamonds spread the diamond grains over their whole volume, and work in a similar fashion to conventional abrasives. Only bonded diamonds can be flattened, lapped, repaired or refreshed. Bonded diamonds are universal and able to sharpen any steel. Bonded diamonds have much better feedback and a longer lifespan.
Yes, Venev diamonds are universal and will wear extremely slowly on both hard and soft steel.
Theoretically, yes. However, sharpening ceramic knives is technically difficult and uneconomical in most cases. Diamond stones can cause microchipping when used on ceramics. Consider purchasing a new ceramic knife instead of sharpening it.
Absolutely not. Coated diamond technology is developed in the USA due to its lower cost. Bonded diamond technology is more advanced and more expensive.
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 first thing to consider while combining stones from different brands is the 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).
Yes. The manufacturer applies FEPA-F grit and national standard GOST 9206 to mark the stone on the reverse side (for example, a 2000 grit diamond is marked "F2000 1/0").
