Description

Venev Unicorn³ Series Dual-Sided Resin-Bonded CBN Stones are designed for use in sharpening systems such as Hapstone and TSProf, as well as for freehand sharpening. CBN (Cubic Boron Nitride) is the second-hardest material after diamond, offering exceptional wear resistance and thermal stability. CBN sharpening stones provide excellent performance when working with high-alloy, powder, and hardened steels.

The Unicorn³ Series represents Venev’s premium-tier dual-sided stones, featuring 3mm CBN-bearing layers bonded to a CNC-milled aircraft-grade aluminum alloy plate. The CBN-bearing layers contain evenly distributed CBN grains within a resin bond. The abrasive layer thickness in the Unicorn³ Series is twice that of the Centaur Series.

Grits F80F240 utilize a wear-resistant boron-modified phenolic resin composite binder (legacy binder). Grits F400F1200 use a proprietary non-abrasive phenolic resin composite binder (OSB binder), providing scratch-free sharpening results.

All Venev CBN stones use FEPA-F grit classification.

⚠️ Attention: Due to the increased thickness of 14mm, Unicorn and Unicorn³ Series stones are not compatible with any stone cases currently offered. The only suitable storage option for the Unicorn Series is the Roll Bag for 6 stones.

How to use
Venev Diamonds are recommended for use with water as a lubricant to achieve the best tactile feedback. The diamond itself does not absorb water. Simply splash a small amount of water onto the stone’s surface. Dry use is also acceptable; however, it leads to faster wear and quicker stone loading.

Dimensions notation.
Monolayer solid abrasives have 3 numbers: length × width × thickness.
Single-sided abrasives with backing have 4 numbers: length × width × full thickness × thickness of abrasive.
Dual-sided abrasives have 5 numbers: length × width × full thickness × thickness of abrasive #1 × thickness of abrasive #2 (both sides)
If thickness is variable, the minimum thickness is noted.
For curved abrasives, a radius of curvature inmm is added: R40.

Metallic Binders (MMC)
  • M2-01 - Copper-tin bronze alloy.
  • MS-1 - Metal-matrix composite (MMC) - Copper-tin bronze alloy reinforced with silicon carbide.
  • MB-1 - Metal-matrix composite (MMC) - Copper-tin bronze alloy reinforced with boron carbide.
  • MS-1A - Metal-matrix composite (MMC) - Aluminum-copper alloy reinforced with silicon carbide.
Resin Binders
  • B1-10 - Boron-modified phenolic resin (BPF) composite - Made of powdered bakelite, copper additive
  • B2-01 - Boron-modified phenolic resin (BPF) composite - Made of liquid bakelite, iron additive (softer than В1-10)
  • В2-01М - Boron-modified phenolic resin (BPF) composite - Made of liquid bakelite, copper additive (softer than В2-01)
  • OSB (OCB) – A proprietary phenolic resin composite.

(OSB and OCB refer to the same binder; the difference arises from a transliteration quirk of the Cyrillic “ОСБ,” which can be rendered as either “OSB” or “OCB” in Latin script.)
