CBN (Cubic Boron Nitride) diamond wheels for knife sharpening offer exceptional performance when it comes to sharpening and honing knife blades. Key performance aspects of CBN diamond wheels for knife sharpening:

  1. Efficient Sharpening: CBN wheels are highly efficient at removing metal from the knife blade, making the sharpening process quicker than many other methods. This is especially beneficial when restoring dull or damaged knife edges.

  2. Consistent Results: CBN wheels provide consistent and repeatable sharpening results. They maintain their shape and sharpness over time, ensuring that knives are consistently sharpened to the desired angles and profiles.

  3. Sharpness: CBN wheels are capable of achieving extremely sharp knife edges. Whether you need a fine edge for delicate slicing or a durable edge for heavy-duty cutting, CBN wheels can accommodate various sharpness requirements.

  4. Longevity: CBN wheels have a long service life due to their exceptional hardness. They wear down slowly, reducing the frequency of wheel replacement, which is cost-effective in the long run.

  5. Cool Cutting: CBN wheels operate at cooler temperatures compared to some abrasive sharpening methods. This prevents overheating of the knife blade, which can lead to damage, and ensures that the blade's temper or hardness is preserved.

  6. Versatility: CBN wheels are versatile and can be used to sharpen a wide range of knives, including kitchen knives, hunting knives, pocket knives, and more. They can also handle both straight-edge and serrated blades.

  7. Clean Sharpening: CBN wheels generate fewer dust and particles during sharpening compared to traditional abrasive wheels, resulting in a cleaner and safer working environment.

  8. Reduced Maintenance: Due to their long lifespan and minimal wear, CBN wheels require less dressing and maintenance compared to abrasive sharpening wheels.

  9. Bevel Angle Control: CBN wheels can help maintain consistent bevel angles, ensuring that knives are sharpened to the desired angles for optimal cutting performance.

  10. Fine Edge Maintenance: CBN wheels are suitable for honing and maintaining the sharpness of high-quality knives, ensuring that the edges remain in top condition for a long time.

  11. Professional Results: Whether used by professional chefs, knife sharpening services, or hobbyists, CBN diamond wheels consistently deliver professional-quality sharpening results.

Grit Range

CBN (Cubic Boron Nitride) diamond sharpening wheels come in various grit ranges to accommodate different sharpening needs and applications. The choice of grit size depends on the type of cutting tool or material you are sharpening and the desired level of sharpness or finish.General overview of common CBN sharpening wheel grit ranges:

  1. Coarse Grit (80 to 180):

  2. Coarse-grit CBN wheels are used for rapid material removal and reprofiling of tools.

  3. Suitable for sharpening heavily damaged or dull tools.

  4. Commonly used for shaping and rough sharpening.

  5. Medium Grit (220 to 400):

  6. Medium-grit CBN wheels provide a balance between material removal and sharpening precision.

  7. Ideal for general-purpose sharpening of tools, including turning tools, chisels, and drill bits.

  8. Suitable for restoring the cutting edge on moderately worn tools.

  9. Fine Grit (600 to 1,000):

  10. Fine-grit CBN wheels are used for achieving a sharp cutting edge with a smooth finish.

  11. Suitable for sharpening and honing woodworking tools, lathe tools, and carving tools.

  12. Ideal for maintaining the sharpness of tools without significant material removal.

  13. Extra Fine Grit (1,200 and above):

  14. Extra fine-grit CBN wheels are used for achieving an extremely sharp and polished edge.

  15. Commonly used for honing and polishing fine woodworking tools, knives, and blades.

  16. Ideal for achieving a mirror-like finish on the cutting edge.


The performance of a Lapidary Faceting Head Mast Arm is crucial to the precision and quality of gemstone faceting. The performance of this component is evaluated based on its ability to facilitate precise cutting and polishing of gemstones. Here are key performance aspects:

  1. Stability and Rigidity: The mast arm should be stable and rigid to securely hold and position the gemstone during faceting. It should not flex or wobble, ensuring that the gemstone remains in the desired position throughout the cutting and polishing process.

  2. Angle Control: The mast arm should allow for precise control of the angle at which the gemstone is presented to the cutting wheel or lap. This angle control is essential for creating facets at the correct angles to maximize the gemstone's brilliance.

  3. Rotation Control: It should provide smooth and accurate rotation control, allowing the faceter to turn the gemstone to cut and polish different facets with precision. The ability to make fine adjustments in rotation is important for achieving symmetry.

  4. Ease of Use: A well-designed mast arm should be user-friendly, enabling lapidarists to easily adjust and fine-tune the position of the gemstone. Smooth and intuitive controls contribute to efficient and effective faceting.

  5. Compatibility: The mast arm should be compatible with different types of faceting machines and equipment. Compatibility ensures that lapidarists can use it with their preferred faceting setup.

  6. Durability: Long-lasting performance is essential. The mast arm should be made from durable materials and built to withstand the wear and tear associated with gemstone faceting.

  7. Precision: Precision is the hallmark of a high-performance mast arm. It should allow for the creation of accurately sized and aligned facets, contributing to the gemstone's overall quality.

  8. Versatility: A versatile mast arm can accommodate various gemstone shapes and sizes, as well as different cutting and polishing laps or wheels. This versatility allows lapidarists to work with a wide range of gemstone types.

  9. Safety: The mast arm should include safety features that protect the user and the gemstone during faceting. Safety shields and guards are common additions to ensure safe operation.

  10. Consistency: The mast arm's performance should be consistent, providing reliable results from one facet to the next. Consistency in cutting and polishing is crucial for achieving a balanced and symmetrical gemstone.

  11. Fine Adjustments: The ability to make fine adjustments is important for achieving precise facet angles and sizes. The mast arm should allow for minute changes when needed.
