Venev Archer³ -Serie Metallic CBN Stone 6 "x 1"

Venev Archer³ Series Metallic CBN Sharpening Stones are used for sharpening knives made of any steel using guided knife sharpeners (Hapstone, TSPROF, and other Edge Pro-compatible sharpening systems). Venev Archer³ ('Archer Cubed') consists of a 3mm-thick CBN-bearing plate mounted on an Edge Pro aluminum base. CBN (Cubic Boron Nitride) is the second-hardest material after diamond. The CBN-bearing plate contains evenly distributed CBN grains with copper-tin alloy bonding for high endurance and low wearing rate.

All Venev stones use FEPA-F grit classification. Archer³ series is available in 5 grits: F80 to F800. For grits above F800, Orion Series resin-bonded stones are recommended.

CBN's qualities include high levels of high hardness, strength, abrasion resistance, and thermal and chemical resistance. These characteristics exceed the values of synthetic diamonds and conventional abrasives such as silicon carbide and aluminum oxide. In particular, CBN's high thermal stability and chemical resistance make it suitable for sharpening in conditions where synthetic diamonds are not normally employed.

CBN offers excellent performance in sharpening knives of any steel. Due to its high resistance specs, CBN can be used dry without lubricant. This makes CBN the cleanest of the available sharpening stones.

Metallic CBN can be used without lubricants.

Metallic CBN stones may have tone imperfections. Metallic CBN may become darker over time due to natural metal oxidizing, but it does not affect the sharpening.

Metallic CBN stones do not require any preparations.

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.)
