Venev Unicorn Series Dual-Sided Resin-Bonded Diamonds are designed for use in sharpening systems such as Hapstone and TSProf, as well as for freehand sharpening. Diamond sharpening stones deliver excellent performance on knives made of any steel.
The Unicorn Series represents Venev’s premium-tier dual-sided stones, featuring 3mm diamond-bearing layers bonded to a CNC-milled aircraft-grade aluminum alloy plate. The diamond-bearing layers contain evenly distributed diamond grains within a resin bond. The abrasive layer thickness in the Unicorn Series is twice that of the Centaur Series.
Grits F80–F240 utilize a wear-resistant boron-modified phenolic resin composite binder (legacy binder). Grits F400–F1500 use a proprietary non-abrasive phenolic resin composite binder (OSB binder), providing scratch-free sharpening results.
All Venev Diamonds 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.
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.
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.)

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.
