FAQ

• Why new Hapstone sharpeners don't support 8" sharpening stones?

  Haptone has 8" stones support since the first version of Hapstone PRO. The best stone form-factor today is 6" Edge Pro. All new knife sharpeners must support it. 8" stones support is declared useless and economically unreasonable.    

• I want to use my 8" bench stones. I will buy a sharpener with 8" stone support. 

  You will not use 8" bench stones even if your sharpener supports 8" stones. Bench stones are too heavy and obstruct visibility.

• Hapstone R2 is smaller than Hapstone R1. Does it mean R1 is better?

  Hapstone R2 becomes smaller for one reason - 8" stone support has been eliminated. The main stone form factor is 6" Edge Pro. Hapstone R2 becomes 2" smaller and lighter.

• Hapstone R2 is much cheaper than Hapstone R1. Does it mean R1 is better?

  Hapstone R2 is available in 4 different kits in different price ranges. Hapstone R2 Classic is the successor of Hapstone R1: triple clamp configuration, fine-tuning adapter, and spring-assisted stoppers. Hapstone R2 Classic is cheaper than Hapstone R1, but the price difference is not big. At the same time, Hapstone R2 has a better stone holder and better clamps.

• How to use new clamps on Hapstone R1? Can I upgrade R1 to R2?

  All new clamps and the new rotating clamp module are incompatible with Hapstone R1. The adapter is in development. Hapstone R1 owners will get it for free with the purchase of a new rotating clamp module.

  
  

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: 150; 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.

Grain table:

Silicon Carbide Sharpening Stones are used for sharpening knives using Hapstone sharpeners. The stones are made of silicon carbide and are designed for the hardest steels (up to 65 HRC). The set of 5 stones: 120, 240, 600, 1000 and 2500 grit (JIS). 

It is advisable to use silicon carbide stones for sharpening knives made of hard stainless steel or carbon steel, such as: ZDP-189, ZDP-247, S30V, S35VN, S90V, S110V, 154CM, D2, YXR7, Cowry, S290, S390, K294, K390, M390, Elmax, 154CPM, ATS-34, 440C, AUS-8, AUS-10, A2, BG-42.. Using silicon carbide stones to sharpen knives made of soft steel is not recommended, as it will cause the stones to wear at the increased rate. However, coarse silicon carbide stones of 120 and 240 grit can be used as a universal stone due to their harder bonding.

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

How to use

HapstoneSilicon Carbide Stones are preliminarily lapped and does not require lapping after purchase.

Silicon Carbide Stones are recommended to be used with water as a lubricant. Soak the stone for 1-2 minutes and splash water on the stone's surface to prevent drying.

FAQ

• What is the difference between Silicon Carbide and Boride CS-HD?

  Both series are extremely good, but it's very difficult to answer the question. Parameters of an abrasive and bonding of Boride CS-HD series is the intellectual property of Boride. We can say for sure that Hapstone  uses harder bonding for 120 and 240 grit, and bonding of equal hardness for 400, 600 and 1000 grit. CS-HD offers 9 grits, while Hapstone  offers 5 grits only.

  
  

  
  

Hapstone Resin Diamond stones are designed for use in hand-held grinding machines such as. Diamond sharpening stones are great for sharpening knives made of any steel.

The Hapstone Diamonds sharpening block consists of a diamond plate with a working surface of 152x25mm with a thickness of 1.6mm, which is glued on an aluminum blank with a size of 160mm, 4mm thick, with beveled dovetail ends. The abrasive layer contains a diamond abrasive uniformly distributed throughout the volume with a high filling density and a very narrow sieving range.

The bar bundle is organic. All of this provides exceptional performance, excellent tactile response and long life for the Hapstone Diamonds.

There are 6 grit sizes in the set

• 80 JIS grit
• 150 JIS grit
• 400 JIS grit
• 800 JIS grit
• 2000 JIS grit
• 5000 JIS grit

Work Sharp Precision Adjust is a fantastic sharpener. The big disadvantage among users of the Worksharp system is the limitation of the three stock sharpening stones mounted on the proprietary holder.

4" (10 cm) Stone Holder for Work Sharp Precision Adjust overcomes the limitation. As of today, you may use any 4" sharpening stones including the KME form-factor and Venev Dog Series dual-side diamonds. 

Note. It's very important to keep a sharpening angle consistent. The angle should not change when progressing to a next stone. If the thickness changes, the sharpening angle changes. Unchecked, this can ruin your sharpening. Use a digital angle gauge to monitor the sharpening angle when you replace a stone in the stone holder. Use the angle adjustment knob of the sharpener if necessary.

Venev Dog Series Dual Side Diamonds are used for guided knife sharpeners or as a pocket sharpening stone. It's the least expensive bonded diamond for guided sharpeners on the market. Diamond sharpening stones offer excellent performance in sharpening knives of any steel.

Dog Series is dual side diamond with two 1 mm-thick diamond-bearing layers on the aluminum plate. The diamond-bearing plate contains evenly distributed diamond grains with resin bonding. The manufacture of bonded diamonds is more complex than for coated diamonds. Bonded diamonds provide better feedback and give the sharpening stone a much longer lifespan.

The OCB version of Venev Diamonds utilizes a brand-new yellow binder with no abrasive particles in the composition. OCB is available in fine grits only and offers better scratch-free sharpening results.

Set composition

Stone set Dog:

• F100 + F240
• F400 + F800

Venev Set  "Dog" is recommended for the full progression with mirror polish result.

All Dog diamonds have 25% diamond concentration.

Specification

• Product size: 98 x 17 x 10 mm
• Abrasive: Synthetic Diamonds with phenol-formaldehyde bonding
• Extra materials: Aluminum
• Flatness tolerance: up to 0.2 mm

How to use

Venev Diamonds are recommended to be used with water as a lubricant for the best feedback. The diamond does not absorb water. Splash water on the stone's surface. Dry usage is an acceptable practice, although it results in faster wearing and speeds up stone loading.

Gunny Juice Polycrystalline Diamond Suspension is a very effective method of honing and polishing the cutting edge of the knife. Gunny Juice is created through a proprietary deionization process offering agglomerate-free dispersion of diamond particles for submicron grits. In conjunction with a very tight particle size distribution, the process permits scratch-free polishing results.

Gunny Juice is available in many grits in 10 ml and 30 ml volume.

The diamond suspension can be used with any strop made of leather, balsa, or nano cloth.

To use, simply pump the desired amount of suspension on your stropping medium, spread evenly, let dry, then use as usual.

You will not be able to fully remove the compound after applying it to the strop. If you want to use your strop both with and without compound, you must, therefore, keep one side clean. If you want to switch between one compound and another, consider buying an extra strop.

Compound residue accumulates in the leather during stropping. If stropping performance gets worse, remove the residue with a knife spine or special tool, and apply the fresh compound.
