Diamond and CBN sharpening stone sets.

Diamond sharpening stones have high productivity and may be used for wide range of materials: carbide, cast iron, HSS, ceramics; not recommended for carbon steels.
Cubic boron nitride sharpening stones are designed for high quality processing of steels. Brand names of CBN are elbor, cubonite, borazon, etc.

Metal bond stones: flat solid block (copper-tin alloy), abrasive grains are distributed evenly across the stone. Metal bond stone does not need support plate, and offers high productivity on rough surfaces, as well as long tool's life. Trademarks: Aldim, PDTools
Resin bond stones: flat solid block (phenol formaldehyde resin), attached to support plate (aluminum blank). Resin bond stones offer high quality of polishing and usually do not clog (do not need lubricant). Trademark: PDTools
Combined bond stones: our innovative solution, which combines best qualities of resin and metal bonds: high performance, mirror polishing and long tool life. Trademark: Aldim
Abrasive stones: low cost solution for your sharpening needs

We sell 3 types of sharpening stones:
- Economy - cost saving product, which quality is enough to satisfy most sharpening requirements.
- Professional - extended service life, because of higher concentration - 200%, comparing to 100% of standard products.
- Standard - all the rest with concentration 100% (150% for some coarse grain sizes). We do not mention trade marks or marketing nicknames (e.g, premium) to be unbiased seller. Most products on the market are also standard, whatever nickname they have, just check concentration.

Beware of fakes and low quality stones
It is almost impossible to find out parameters of sharpening stone (grain size, concentration) visually. Some sellers offer Ukrainian (to underline quality) sharpening stones, which, in fact, are poor or medium quality products, made using basic technologies.
Ask for Poltava sharpening stones, made by two factories, located in this capital of European industry of superabrasives. Stones are numbered, as well as accompanying passports, so you can always track product.
And, yes, Poltava is a city in Ukraine :)

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.

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.

CBN SHARPENING STONES, COMBINED BOND, 200x30 (CBNST200)

CUBIC BORON NITRIDE, CBN, BORAZON
HONING, SHARPENING STONES
200-30-8-3-5
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.

Length: 200 mm = 7.9 inch
Width: 30 mm = 1.2 inch
Total thickness: 8 mm = 0.32 inch
CBN thickness: 3 mm = 0.12 inch
Blank thickness: 5 mm = 0.2 inch

Bond: innovative combined bonds to ensure the best performance, resin bond BP50 for polishing at fine sizes and metal-resin bond BP05 for grinding at coarser grain sizes.

Grain size: Please select from the list, or read Technical information.

Do not waste your money on cheaper stones with lower/unknown concentration.

Flat solid block on aluminum blank.

Available on stock

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.

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.

Bonds:
Resin bond: phenol-formaldehyde, does not require lubricant, but you may use water (or water based cooling liquids)
Metal bond: M2-01, copper-tin

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

Available on stock

Preparation of sharpening stones
These stones 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 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.

CBN SHARPENING STONES METAL BOND, 200x40, 200x70 (CBNST200)

CUBIC BORON NITRIDE, CBN, BORAZON
HONING, SHARPENING STONES
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.

Length: 200 mm
Width: 40, 70 mm

Metal bond, may require 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

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

Flat solid block, abrasive grains are distributed evenly across the stone.
200-40-5 - on aluminum blank
200-70-3 - without blank
You may also buy aluminum blank separately, if you buy stone.

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 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.

Bonds were designed to be as wear resistant as metal bonds, but work more softly

1/0- 63/50 - copper-resin bond BP50 for polishing

> 80/63 - copper-resin BP05, wear-resistant, for grinding

There were issues of shedding of grains, which was visible on coarse grain sizes, so we replaced existing bond BP08 (coarse grits >160/125) for harder bond BP05. We still have stock of CBN stones with soft BP08 bond, please contact us if interested.

Grain size: Please select from the list, or read Technical information.

Grain concentration: 200%

200% stones were designed on request of professional sharpeners, who wanted to sharpen faster. According to feedback, the increase of productivity was about 50%, and this was and remains a reason to pay a higher price.

200% combined bond stones offer high sharpening speed, but wear off faster, which is visible (shedding of grains) on coarse grain sizes: 40/28 and coarser.

Flat solid block on aluminum blank.

Application
For knife sharpening using such sharpeners as Hapstone, Edge Pro, Kazak Pro.

CBN SHARPENING STONES, COMBINED BOND, 150x25 (CBNST)

CUBIC BORON NITRIDE, CBN, BORAZON
HONING, SHARPENING STONES
150 х 25 х 7 x 3 x 4

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.

Length: 150 mm = 6 inch
Width: 25 mm x = 1 inch
Total thickness: 7 mm = 0.28 inch
CBN thickness: 3 mm = 0.12 inch
Blank thickness: 4 mm = 0.16 inch

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.

Special resin bond B1-13, 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 0.25/0 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.

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

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.

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).

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.
