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.

Preparação de pedras de afiar
Essas pedras requerem preparação (afiamento), caso contrário, elas se autopolirão após a afiação de 30 a 50 facas. Elas ficarão com uma cor dourada e funcionarão bem.

Este é um problema comum a todos os fabricantes: os grãos abrasivos são cobertos por uma camada de ligante, então é necessário "liberá-los".

Uso e limpeza de pedras de afiar
Use qualquer óleo suave (óleo de bebê, azeite de oliva...) para evitar o vitrificação. Se vitrificado, limpe com álcool e uma escova de dentes.

Manutenção (a cada 1-2 anos), aplainamento/revitalização:
- Pedras com liga de resina - com pó de carbeto de silício (sílica) em placa de vidro,
- Pedras com liga metálica - com FeCl₃.

- 10 minutos de imersão em uma mistura a 25% (25 g de FeCl₃ para 75 g de água),
- 10 minutos de polimento com movimentos (desenhe cuidadosamente um "8") em uma placa de vidro.
Você pode comprar 100 g de FeCl₃ na janela de seleção de grãos. Eu vendo junto com a compra de uma pedra.
