The set of Boride stones is collected from various series and is intended for sharpening of knives from any steels. The set includes 5 stones with a grain size: 100; 220; 400; 600; 1200, which will be enough for all stages of sharpening, from peeling to the final grinding. And the smooth reduction of grain, from stone to stone, guarantees efficient sharpening with minimal time.

  All stones are 6 mm thick and mounted on high-quality aluminum blanks with laser engraving

You can work both "dry" and with ordinary water (or a little soap). It is not recommended to use force and pressure during sharpening / finishing!

Does not require special care. Cleaned under running water with a soapy stiff brush (can be a toothbrush). Align after formation on silicon carbide.

Note: Boride stones can have the following defects: saw marks on the work surface, minor chips at the corners and edges (no more than 1 mm).

From myself: Stones are very good in work, on quality favorably differ from stones of the Ukrainian production. They are made of different materials and on different bonds, which makes them very versatile in relation to work with different steels. Work with both water and oil.

. Boride stones are made of aluminum oxide, with the exception of CS-HD series stones, which are made of silicon carbide. All Boride stones are 6 mm thick and are mounted on high quality aluminum blanks. Stones that are 6 mm thick offer a longer life cycle than stock Edge Pro stones that are 3 mm thick and are becoming a community standard.

PC series (Polisher's Choice) stones are made of aluminum oxide with grain that is strictly controlled and a special bond. As you might have guessed from the name of the series, these stones are designed for finishing operations with fast removal. PC 1200 grit is very popular as a finishing stone and is part of Boride stone bundles.

The Boride PC recommended set includes these grit sizes :

•     150
•     220
•     400
•     600
•     1200

Hapstone Premium CBN

These stones are made from CBN powder (cubic boron nitride). Hapstone Premium CBN uses a metal-organic bond, which is close to metal in terms of its wear resistance, but the bar on this bond works softer.The stones are mounted on a blank (powder-coated) of high quality aircraft-grade aluminum.

 Hapstone Premium CBN is ideal for both modern "super steels" and for the sharpening of ceramic knives. 

There are 6 grit sizes in the set

• Hapstone Premium CBN  80 grit 
• Hapstone Premium CBN 150 grit 
• Hapstone Premium CBN 400 grit 
• Hapstone Premium CBN 800 grit 
• Hapstone Premium CBN 2000 grit 
• Hapstone Premium CBN 5000 grit 

Benefits of sharpening knives with Hapstone Premium CBN stones:

• Comfort in work — the stone is hard enough but comfortable in work. It is often compared to Japanese water stones, but Hapstone Premium CBN is ten times more durable than them.
• Unpretentiousness — stones for knives made of boron nitride do not require additional care, which cannot be said about natural and synthetic stones for sharpening of knives. These bars do not require the application of cutting fluids (coolants).
• Delicate processing — CBN grains work softer and more productively, while not leaving unwanted scratches on the cutting-edge during the sharpening of a knife. This is due to the fact that CBN has an octahedron-shaped crystal structure — it has more cutting edges, but corners are less sharp, which gives a good mirror result. 
• Versatility — the presence of bars of different grain sizes, but of the same size (150x24x5mm, the thickness of the working layer – 3 mm) allows to change the stones depending on the stage of processing without changing the angle of knife sharpening:

• High performance of CBN for knife sharpening — an excellent result is achieved due to the concentration of 100% CBN grain of CBN1 type. 

For finishing, we recommend to use Gunny Juice diamond suspension.

Characteristics:

•     Stone size: 150x24x3mm
•     Powder-coated blank size: 160x24x5mm
•     Bond: metal-organic
•     Material: СBN (cubic boron nitride) 
•     Concentration: 100%

Diamond bars for knife sharpening are very popular on the market — due to their characteristics, they can be used to sharpen knives made of any material, without losing their properties for a long time. As the grindstone wears out, new diamond particles are exposed. The stones is mounted on an anodized blanc- made of high-quality aviation aluminum.

That is why the stone continues to sharpen at the same speed without any loss in performance. Hapstone Premium Diamond is ideal for modern "super steels" and for the sharpening ceramic knives. These bars use a metal-organicbond, which is close to metal in terms of its wear resistance, but the bar on this bond works softer.

Benefits of Hapstone Premium Diamond stones:

• Efficiency of work and excellent tactile response — a Diamond has a tetrahedral crystal structure, which has fewer cutting edges and sharper corners. This leads to "aggressive" operation of the diamond during finishing and further finishing. 

Hapstone Premium Diamond has a pleasant tactile response that can be compared to water stones, but the service life of Hapstone Premium Diamond stone is ten times longer and lasts for an incredibly long time.

• Unpretentiousness — Hapstone Premium Diamond stones do not require additional care or the application of cutting fluids (coolants) before sharpening the knife, which makes them comfortable in usage and clean in the workplace.
• Performance— Hapstone Diamonds have an excellent result which is achieved due to the concentration of 100% diamond grain. 
• Easy to clean — you can clean the surface of the stone with Hapstone Dressing Stone (it is designed for fine cleaning of the working surface from very fine-grained stones, removal of metal chips from the intergranular space (greasing)..

Hapstone Start CBN stones are designed for use in Hapstone sharpening systems and are excellent for sharpening knives of all steels.The Hapstone Start CBN sharpening stone consists of a CBN plate with a 152x25mm work surface, 3mm thick, which is bonded to a 160mm aluminum blank, 5mm thick, with beveled ends for a secure hold.

The abrasive layer contains CBN abrasive, evenly distributed throughout with a high fill density and a very narrow screening range. Very fast and aggressive metal removal thanks to the electroplated coating. They work much faster than any other diamond.

The abrasive layer contains a diamond abrasive uniformly distributed throughout the volume with a high filling density and a very narrow sieving range.

Very fast and aggressive metal removal thanks to electroplating. They work much faster than any other Diamond. And because of the multiple plating layers, they last many times longer than cheaper counterparts.

Empty Blanks are used with sharpening stones on Hapstone  knife sharpener. Edge Pro sharpening stones are fragile and need to be attached to Empty Blanks. This adds rigidity and increases the lifespan of the stones. Empty Blanks have a standard 45-degree bevel and are made of high-quality 3 mm thick aluminum.

Small Whole milled angled clamps Hapstone RS  are made from a solid piece of aircraft-grade aluminum and anodized in black.
Anodizing is used to improve the corrosion resistance and strengthen the aluminum surface structure.

The knife is fixed with one screw that is convenient and fast (in contrast to Universal angled clamps for Hapstone ) These clamps also have an undercut for sharpening knives with a full flat grind.  

This type of clamp provides the greatest rigidity when sharpening. With these clamps, it becomes possible to sharpen knives with Scandinavian descents of kitchen knives, fixes, and EDC knives.
These clamps are also suitable for fillet knives
