CBN SHARPENING STONES METAL BOND, 150x25, 150x50 (CBNST150)
CUBIC BORON NITRIDE, CBN, BORAZON
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: 150mm
Width: 25, 50 mm
Height: 3 mm
Total height (with blank): 7 mm

Metal bond M2-01, may require lubricant.
Flat solid block on aluminum blank, abrasive grains are distributed evenly across the stone.
Grain size: Please select from the list, or read Technical information.
CBN concentration: 100%
Do not waste your money on cheaper stones with lower/unknown concentration.
Available on stock
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 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.

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.Selection of SiC powders for dressing of sharpening stones

Bond: combined (hybrid) 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 - 500/400 micron (rough grinding).
In grain selection window you see grain sizes according to standards:
MICRON=MESH(GRIT)=FEPA
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
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.
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.
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.
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.

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.
