CBN SHARPENING STONES
 
CBN (cubic boron nitride) is a generic name, there are also other names of this material, depending on manufacturer: borazon, elbor, cubonite, etc. 
CBN (cubic boron nitride) is the second-hardest material after diamond,  and has the best price-performance ratio for processing steels, comparing to other materials, including diamond, silicon carbide or aluminum oxide.  
Due to it's high resistance specs, CBN can be used dry without lubricant. This makes CBN the cleanest of the available sharpening stones.  


Length: 150 mm = 6 inch
Width: 25 mm = 1 inch
CBN height: 2 mm = 0.08 inch

In grain selection window you see grain sizes according to standards:
MICRON = MESH(GRIT) = FEPA

Grain concentration: 100%
Do not waste your money on cheaper stones with lower/unknown concentration.
Concentration 200%- on order, 50% more expensive. 

Flat solid block on aluminum blank.
You may also buy aluminum blank separately, if you buy stone.

Available on stock 

Application
For knife sharpening using such sharpeners as Hapstone or Edge Pro.

Preparation of sharpening stones
Stones with grits finer 3 microns either require preparation on cast iron plates, or they will be self-polished after sharpening of 30-50 knives. Then they will be of gold color and work well.
This is common issue for all manufacturers, unless stones are prepared before shipment.
So there's "Stone preparation" option in grain selection window.

Use and cleaning of CBN sharpening stones
Use any comfortable oil (baby, olive..) to prevent glazing. If glazed - clean with alcohol and toothbrush.

Maintenance is only needed every year or two.
In 1-2 years you may need to flatten stone, 20 mins with Ferric chloride (FeCl):
- 10 mins setting in 25% mixture (25 gr FeCl per 75 gr of water),
- 10 mins polish movements (carefully draw "8") on glass plate.
There are other methods (with SiC powders..), but method with FeCl, on glass plate is the cheapest and simplest.
You may buy 100 gr. of FeCl in grain selection window. I sell it if you buy a stone.
