Hapstone Premium CBN

These stones are made from CBN powder (cubic boron nitride). Hapstone Premium CBN uses a metal-organic bond, which is close to metal in terms of its wear resistance, but the bar on this bond works softer.The stones are mounted on a blank (powder-coated) of high quality aircraft-grade aluminum.

 Hapstone Premium CBN is ideal for both modern "super steels" and for the sharpening of ceramic knives. 

There are 6 grit sizes in the set

  • Hapstone Premium CBN  80 grit 
  • Hapstone Premium CBN 150 grit 
  • Hapstone Premium CBN 400 grit 
  • Hapstone Premium CBN 800 grit 
  • Hapstone Premium CBN 2000 grit 
  • Hapstone Premium CBN 5000 grit 

Benefits of sharpening knives with Hapstone Premium CBN stones:

  • Comfort in work — the stone is hard enough but comfortable in work. It is often compared to Japanese water stones, but Hapstone Premium CBN is ten times more durable than them.
  • Unpretentiousness — stones for knives made of boron nitride do not require additional care, which cannot be said about natural and synthetic stones for sharpening of knives. These bars do not require the application of cutting fluids (coolants).
  • Delicate processing — CBN grains work softer and more productively, while not leaving unwanted scratches on the cutting-edge during the sharpening of a knife. This is due to the fact that CBN has an octahedron-shaped crystal structure — it has more cutting edges, but corners are less sharp, which gives a good mirror result. 
  • Versatility — the presence of bars of different grain sizes, but of the same size (150x24x5mm, the thickness of the working layer – 3 mm) allows to change the stones depending on the stage of processing without changing the angle of knife sharpening:

  • High performance of CBN for knife sharpening — an excellent result is achieved due to the concentration of 100% CBN grain of CBN1 type. 

For finishing, we recommend to use Gunny Juice diamond suspension.
