RECOMMENDED SETS OF DIAMOND AND CBN STONES, METALL AND RESIN BONDS
 
Recommended selections of sharpening stones to make your choice easier:
- Highlight your operations: do you have "forming cutting edge" operation ?  What surface quality do you need, just "nice at eyesight" (polishing) or mirror (the finest polishing). So skip sets with unnecessary grains. 
- What is your workload ? If from time to time - skip metal bond stones, they are more expensive, but lasts longer. 
- The more knives you sharpen, the more you need stones, to keep steps in working operations (distances between grain sizes) shorter.

Special resin bond BN-130,  does not require cooling, but you may use water (or water based cooling liquids) as lubricant.
Metal bond on order 

Grain size: Please select from the list, or read Technical information.  
The finest grain size is 0.5/0 micron (fine polishing) , the coarsest - 200/160 micron (rough grinding). 
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. 
 
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 (dressing), 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: abrasive grains are covered with bond, so you need to "release" them. 
"Stone preparation" is not available because of war.

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

Maintenance (in 1-2 year), flattening/revitalization:
- resin bond stones - with silicon (silica) carbide powders on glass plate,
- metal bond stones - with 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.
