Description

Attention! The Centaur series now includes F1200 + F1500 grit combination.

Venev Centaur Series Dual Side Diamonds are used for sharpening knives on Hapstone and TSProf guided knife sharpeners, as well as freehand sharpening. Diamond sharpening stones offer excellent performance in sharpening knives of any steel.

Centaur Series is dual side diamond with two 1mm-thick diamond-bearing layers on the aluminum plate. The diamond-bearing plate contains evenly distributed diamond grains with resin bonding. The manufacture of bonded diamonds is more complex than for coated diamonds. Bonded diamonds provide better feedback and give the sharpening stone a much longer lifespan.

The OCB version of Venev Diamonds utilizes a brand-new yellow binder with no abrasive particles in the composition. OCB is available in fine grits only and offers better scratch-free sharpening results.

All Venev diamonds use FEPA-F grit classification. Centaur Series is available in five grit combinations. F80 to F240 utilize legacy binder, F400 to F1500 utilize OCB binder. Orion series is available only in 100% diamond concentration.

How to use

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 0.2mm. 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 is not recommended.

 

FAQ

  • Which type of diamond is better bonded or coated?

    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 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.

  • Can I buy Venev diamonds to sharpen all my knives? If they are okay for hard steel, they should be even better for soft steel, right?

    Yes, Venev diamonds are universal and will wear extremely slowly on both hard and soft steel.

  • Can I sharpen ceramic knives with Venev diamonds?

    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.

  • Well-known manufacturers like DMT and Eze-Lap use coated diamonds in their products. Doesn't that mean bonded diamonds are inferior?

    Absolutely not. Coated diamond technology is developed in the USA due to its lower cost. The bonded diamond technology is more advanced and more expensive.

  • 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).

  • Does Venev use the FEPA grit scale?

    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").

No, Edge Pro unfortunately designs their systems only to work well with Edge Pro type stones or similar 6 inch dovetail backed type stones.

It's perfectly fine to use diamond or CBN stones like these on any steel, including high carbon basic alloy steels like those used in many Japanese knives.

No, it works as-is. Just use a bit more spring tension than normal but adjusting the size smaller than regular 6 inch stones.

Is it possible work with WD-40 rather than water? Any benefits?
avatar
⚙️Leading Edge  •  8 months ago
If you prefer an oil-based lubricant rather than soapy water, it is recommended to use plain mineral oil or better yet - oleic oil rather than WD-40.

The benefit of soapy (very diluted dish soap) water, is the fact that the stones are cleaner when you're storing them. Oil works well, but the stones are messier during storage and you likely won't be able to go back to soapy water after oil has been used on your stones.

Like waterstones?

⚙️Leading Edge  •  10 months ago
Yeah, that will work. The bond is similar to many hard waterstones.

The previous 2000 grit Venev stones were found to have agglomeration of diamond particles, leading to stray scratch patterns below the grit rating. 1500 grit Fepa-F is a great final finish for knives and a good starting point for mirror polishing with loaded strops.

Yes, they do work very well if used with the standard Edge Pro stone mounting method of tightening the handle against the original brass sleeve. If you have modified your Edge Pro with a spring for the stone holders, it may or may not work well - depending on the length and tension of the spring you have. A short or weak spring will not hold as securely as the original handle tightening method of clamping stones.
