Description

Metallic CBN Sharpening Bench Stones are used for freehand sharpening knives. CBN (Cubic Boron Nitride) is the second-hardest material after diamond.

CBN's qualities include its 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 stones utilize copper-tin alloy bonding for high endurance and low wearing rate. Metallic CBN Stones consists of a 3 mm thick CBN-bearing metal plate mounted on a 10 mm thick glass base.

    How to use

    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, it does not affect the sharpening.

    Metallic CBN stones do not require any preparations.

    Q & A

    • CBN sounds like a wonderful abrasive that is far better than anything else on the market. So what's the catch?

      CBN offers high performance, sharpens any steel, has a low wear rate and little loading, creates no mess and makes no unwanted grooves. The catch is the price - it's expensive.

    • Can I sharpen ceramic knives with CBN?

      Theoretically, yes. However, sharpening ceramic knives is technically difficult and uneconomical in most cases. CBN stones can cause microchipping when used on ceramics. Consider purchasing a new ceramic knife instead of sharpening it.
