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.

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.

Use and cleaning of diamond 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 dimensions selection window (click also any grain size to select it). I sell it if you buy a stone.

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.
Italian Black Slate - has good finishing properties, which are close to dark Thuringian shales, but Italian Black Slate is a little harder, which is undoubtedly an advantage when working in apexoid type sharpeners. The slate gives a very moderate fine white suspension. It works with all steels, removing scratches on the cutting edge, and exposing their structures, adding sharpness.
152 mm — length, 25 mm — width, 7 mm — total thickness,
4 mm - the thickness of the working layer, 3 mm - thickness of the aluminum blank.
Superfinishing stone, it is recommended to switch to it after abrasive with a grain of at least F1000-F2000, or superabrasive (CBN, diamond) 5/3, 3/2, 2/1, 1/0
Each stone is equipped with a slur (a small stone for guiding the suspension). The recommended lubricants/coolants are water, oil.
Quality Italian leather on aluminum blank — polished and does not require additional processing. It is used for applying polishing paste and further sharpening the cutting edge of the knife. It can also be used without paste.
Length: 160 mm, Width: 25 mm, Thickness: 7 mm
Linden on a aluminum blank - for applying polishing paste and polishing the cutting edge of the knife.
Length: 160 mm, Width: 25 mm, Total thickness: 7 mm, The thickness of the aluminum blank - 3 mm.

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