Cubic boron nitride is an extremely hard synthetic, crystalline material. CBN is superior in terms of abrasion resistance and oxidation resistance in contact with steel alloys. It is especially good to use for stainless steel knives and hardened stainless steel cutting tools. CBN is not harder than diamond but is thermally and chemically more stable than pure diamond. Another feature of the CBN sharpener is that it retains its shape no matter how much it is used. In addition, this coating is located on both sides of this profiled stone. Grit size 25 micron, e g “fine”.
How to use your CBN whetstone:If your knife is dull, we advise you to start with the diamond stone. After restoring the edge to original shape, de-burr the edge lightly with the stone in order to get a razor-sharp edge.Use no oil or water.Start by laying the blade flat on the stone, raise the blade spine approx. the thickness of the blade, and start moving the knife in circular motions.The ink trick:Colour the edge with a felt-tip pen. You can check your progress in sharpening the knife by observing where the colour is removed.How to check the sharpness:To check the sharpness of your knife, pull the edge very lighly on your finger nail. If it cuts, the knife is certainly sharp enough for most tasks. Dimensions: 85 mm X 54 mm X 3.6 mm
