Venev Gemini Series Curved Diamonds are designed for sharpening inwardly curved blades in sharpening systems such as Hapstone and TSProf. Diamond sharpening stones deliver excellent performance on knives made of any steel.
Gemini Series Generation 2 is updated curved diamonds featuring Metal Matrix Composite (MMC) binders. MMC is a new generation of metallic binders. Gemini Gen.2 utilizes a reinforced copper–tin bronze alloy MMC: MS1 binder for F80–F800 grits and MB1 binder for F1200.
Gemini stones consist of a diamond-bearing layer with curved working surface on a metal backing. The diamond-bearing layer contains evenly distributed diamond grains with metal bonding. Metal bonding gives the sharpening diamond stone a long lifespan.
All Venev Diamonds use FEPA-F grit classification.
- Working surface: 150 x 12mm (6" x ½")
- Abrasive: Synthetic Diamonds with copper-tin alloy bonding
- Curvature: 50mm
- Geometry tolerance: up to 0.2mm
Metallic 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 geometry tolerance up to 0.2mm. Because diamonds are curved, extra lapping by a customer is not permitted. Gemini diamonds don't require any preparations.
Gemini diamonds may seem bald out-of-the-box. This is normal.
Metallic diamonds may become darker over time due to natural metal oxidizing. It does not affect the sharpening.
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.
