Bond: combined bonds to ensure the best performance.
Grain sizes: 1/0- 63/50 - resin bond BP50  for polishing
Grain sizes 80/63 - 160/125 - wear resistant metal-resin bond BP08 for grinding
Grain sizes 200/160 - 500/400 - metal-resin bond BP05 for roughing

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

Diamond concentration: 100%
Do not waste your money on cheaper stones with lower/unknown concentration.

Flat solid block on aluminum blank, abrasive grains are distributed evenly across the stone.

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 dimesions selection window.

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

Maintenance (in 1-2 years), flattening/revitalization:
- resin bond stones -  with silicon (silica) carbide powders on glass plate,
- metal bond stones - with FeCl.   
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 dimensions selection window (click also any grain size to select it). I sell it if you buy a stone.
