Venev Sculptor Series Narrow Diamond 6" x ½"

Venev Sculptor Series Diamonds are designed for expert knife sharpening in systems such as Hapstone and TSProf. Diamond sharpening stones provide excellent performance on knives made from any steel. Narrow stones (12mm wide) are ideal for recurved blades.

Sculptor Series features Metal Matrix Composite (MMC) binders. MMC represents a new generation of metallic binders. The Sculptor line uses a reinforced copper–tin bronze alloy MMC: MS1A binder for F80–F240 grits, MS1 binder for F400–F800 grits, and MB1 binder for F1200.

Sculptor stones consist of a 2mm abrasive layer mounted on a 3mm anodized aluminum backing. The reduced weight (approximately 40 grams) improves balance and makes it easier to control pressure during sharpening.

All Venev Diamonds use the FEPA-F grit classification.

Attention! Sculptor diamonds are very fragile. Apply only minimal pressure to avoid damaging the stone.

Metallic Diamonds are recommended for use with water as a lubricant to provide the best tactile feedback. The diamond layer does not absorb water; simply splash a small amount on the surface before sharpening. Dry use is acceptable but leads to faster wear and quicker stone loading.

Metallic diamonds may darken over time due to natural metal oxidation. This cosmetic change does not affect sharpening performance.

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.)

Pressure control means applying only the minimum, steady force needed for the abrasive to begin cutting. With guided systems, you are holding the stone, guide rod, and stone holder in the air, so the total mass matters. A lighter setup improves tactile feedback and makes it easier to keep pressure consistent.

Why It Matters

• Edge integrity: Excess pressure can bend the apex and move contact away from the actual cutting edge.
• Cutting efficiency: Too much force causes metal deformation instead of clean cutting, reducing sharpness and polish.
• Abrasive wear: Overload accelerates uneven wear, grain chipping, and unwanted scratches.
• Geometry control: High force makes it harder to maintain angle accuracy, especially on thin bevels or low angles.
• Heat and fatigue: More pressure creates excess friction and heat, which can harm both the edge and the user’s consistency.

Best Practices

• Start light: Increase pressure only until you feel the abrasive begin to cut, then keep it steady.
• Reduce with finer grit: The finer the stone, the lighter the touch required.
• Maintain consistency: Equal pressure on both sides removes previous scratches and ensures even refinement.
• Use smooth strokes: Controlled, deliberate movements improve feedback and angle stability.
• Keep it lightweight: Choose light stones, guide rods, and holders for better control and less hand strain.

When Pressure Is Too High

• Loss of bite: The abrasive stops cutting effectively even as force increases.
• Edge rollover: The apex deforms or folds, forcing a return to a coarser grit.
• Random scratches: Damaged abrasive grains leave isolated, deep marks.
• Uneven stone wear: The surface loses flatness faster, reducing accuracy and finish quality.

Bottom line: Let the abrasive do the work. Light, steady pressure with a lightweight setup yields sharper edges, longer stone life, and more predictable results.
