Bonds: Metal M2-01 (copper-tin), Combined (copper-resin, depending on grain size)
Flat solid block on aluminum blank.
Grain size: Please select from the list, or read Technical information.
Grain concentration: 100%
Do not waste your money on cheaper stones with lower/unknown concentration.
Available on stock
Application
For sharpening of curved blades using such sharpeners as Hapstone, Edge Pro, Kazak 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.
Selection of SiC powders for dressing of sharpening stones
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.
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.

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
