Gunny Glide in the center of the graphene revolution

If we live in simulated reality, graphene is a cheat code.

The unique properties of graphene and its derivatives are the major areas of interest, each of which seems to be superior to rival materials. This material boasts a plethora of unique properties that include: high mechanical strength, high thermal and electrical conductivity, extremely large surface area, and barrier/membrane properties. The intrinsic properties of graphene have resulted in graphene having many potential practical applications in the areas of electronics, optoelectronics, sensors/detectors, composites/barriers, fundamental metrology. Graphene is poised to become a central component of the energy infrastructure, computer chips, bioelectronic eye implants, flexible screens, rapid removal of the most toxic and radioactive human-made radionuclides from contaminated water after nuclear disasters. It won’t be very long before almost every industry is disrupted by it.

Venev Diamonds: Orion vs Centaur

FAQ. I wonder which Venev diamond is better - Orion or Centaur?

Answer. Orion diamonds are easier to use and have a longer life cycle.

1) Orion is mounted on the aluminum blank so it is clamped in a guided sharpener really well.

Centaur stones are without blank. Modern sharpeners can use rectangular stones, but there is always room for mistake.

Sneak Peek: Venev OCB Bonded Diamonds

Posted by KONSTANTIN MARTYNENKO

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

Venev OCB Diamonds are available in F 1200 grit (2.5 um) only. F 800 grit (6 um) will be released in Q1. Dual-sided formats of OCB will be released at the same time.

  • I have the original Venev diamond stone 1200 grit. Do I need the OCB?

    Legacy binder composition includes medium-hard particles up to 7 microns large. (It was necessary to stabilize diamond/binder matrix.) As result, when sharpening some steels the legacy F 1200 and F 2000 may not show noticeable progression after F 800. In this case, the new OCB diamonds will be the good upgrade.

  • Do I need to lap OCB diamonds?

    We recommend lapping all Venev diamonds including OCB because flatness tolerance is the same as for legacy diamonds. However, it's not mandatory for OCB version because the surface is finer.

  • How about OCB F 2000 grit?

    It will not be released due to substantial technology limits. F 2000 will be legacy only.

No product we ever mentioned in social networks, forums and tradeshows, has been canceled. However, all upcoming or out-of-stock Hapstone products are  "Done, when it's done".
