RECOMMENDED SETS OF DIAMOND AND CBN STONES, METALL AND COMBINED 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.
- CBN combined bond stones are recommended for all types of steels;
- The more knives you sharpen, the more you need stones, to keep steps in working operations (distances between grain sizes) shorter.

Bonds
Metal bond: M2-01, copper-tin
Combined bond: composition depends on grain size, does not require cooling, but you may use water (or water based cooling liquids) as lubricant.
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.
Available on stock
Application
For knife sharpening using such sharpeners as Hapstone, Edge Pro. etc.
Preparation of sharpening stones
Stones with grits finer 3 microns may 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.

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.
- 10 mins setting in 25% mixture (25 gr FeCl per 75 gr of water),
- 10 mins polish movements (carefully draw "8") on glass plate.

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.

Preparation of sharpening stones
Unlike other sharpening stones, most of these combined bond stones do not need preparation, except stones with grits finer 1 microns (<Grit 15000). Ultrafine grains (1/0, 0.5/0) form agglomerates in a bond, so you may need to dress them with abrasive powders/pastes, or they will be self-polished after sharpening of 30-50 knives.

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 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.

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, but SiC powders are also OK

Description of products in this set.
CBN (cubic boron nitride, borazon) stones are well known for high hardness and resistance to high temperatures and various chemical components of alloys and steels.
Comparing CBN and diamond grains, we must admit, that CBN works softer and more productively, while at the same time it does not cause yellowing scratches on the cutting edge. This is due to the fact that CBN has a crystal structure in the shape of an eyepiece - the number of cutting edges is greater with less sharp corners - resulting in softness during processing and high productivity. Diamond has a crystal structure in the form of a tetrahedron, with fewer cutting edges and sharper corners of the crystal, which leads to more "aggressive" work of the diamond
The following grains are available(please contact us to change set content): 0.5/0; 1/0; 2/1; 3/2; 5/3; 7/5; 10/7; 14/10; 20/14; 28/20; 40/28; 50/40; 63/50; 80/63; 100/80; 125/100; 160/125; 200/160; 250/200; 315/250.
Quality Italian leather on aluminum blank, used for applying polishing paste and further sharpening the cutting edge of the knife. It can also be used without paste.
Glossy leather - for fine grits.
Length: 160 mm, Width: 25 mm, Thickness: 7 mm

How to maintain sharpening stones
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.
