Description

Attention. The current (second) revision of Hapstone M2 implements the linear ball-bearing pivot unit. Owners of Revision 1 can purchase the linear ball-bearing pivot unit separately.

The metal pivot unit with the linear ball-bearing provides extra smooth shaft movement and requires no lubrication or cleaning.

Hapstone M2 is the new middle-stream knife sharpener from Hapstone, the supplier of successful Hapstone V7. Focusing on what matters most for knife sharpening enthusiasts, Hapstone M2 is a combination of precision, durability and great value.

The linear bearing equipped instrument, is by far the smoothest, and virtually play-free, guided rod system I've used thus far. There is no vibration, or perceivable movement, but its able to simultaneously exhibit extremely precise and smooth reciprocating, linear action.
 Daniel Gigli, Quality Technician/Engineer

Hints

Here is a brief guideline for stone bundle choosing.

  • Do you own a sharpening stone collection compatible with Hapstone? Choose Basic Bundle.
  • You have EDC / Hunting / Tactical / Traditional Japanese knives made of powder steel (ZDP-189, ZDP-247, S30V, S35VN, S90V, S110V, 154CM, D2, YXR7, Cowry, S290, S390, K294, K390, M390, Elmax) or traditional hard steels (154CPM, ATS-34, 440C, AUS-8, AUS-10, A2, BG-42)? Choose Silicon Carbide Bundle.
  • You have Kitchen / EDC knives made of soft carbon or stainless steel (1095, 1080, 1070, 1050, 420, 440A, 440B, 3Cr13, 8Cr13MoV, 8Cr14MoV, 9Cr14MoV, AUS-4, AUS-6)? Choose Aluminum Oxide Bundle or Boride Bundle.
  • Diamonds have substantial advantages to traditional abrasives: they are universal, can be used dry, and have a long life. Unfortunately, there are disadvantages too: microchipping and deep scratching (especially on powder steels), weaker feedback. It's recommended to flatten and lap diamonds, so we don't recommend diamond bundle to inexperienced users. If you consider it a good compromise, choose Diamond Bundle.

How to use Hapstone M2 Sharpener

Hapstone M2 knife sharpener is shipped disassembled and requires assembling. Please refer to User's Guide.

How to use bundled stones

Basic

Basic stones are made of silicon carbide. Water is required to use. Immerse all stones in water for 10 minutes before use and keep them wet during the work. Do not keep the stones in water for a long time.

Silicon Carbide

Bundled stones are made of silicon carbide. Water is required to use. Immerse all stones in water for 10 minutes before use and keep them wet during the work. Do not keep the stones in water for a long time.

Stone set is optimized for sharpening knives made of hard steels. You can use 120 and 240 grit stones on soft steel knives. Using 600, 1000 and 2500 grit stones with steels with hardness less than 58 hRC is not recommended.

Aluminum Oxide

Bundled stones are made of aluminum oxide. Water is required to use. Immerse all stones in water for 10 minutes before use and keep them wet during the work. Do not keep the stones in water for a long time.

Stone set is optimized for sharpening knives made of soft steels. Using the stones with steels with hardness more than 59 hRC is not recommended.

Diamond

Bundled diamonds are dual-sided, one side is coarsier than other. Three stones have total six grits. It is little bit tricky to identify grits. You can find identification marks on side face. The mark is grit specified in FEPA-F scale with arrow symbol facing to corresponding surface. A finer side is always copper colored.

All diamonds are bonded, not coated. It means you can clean, refresh, flatten and lap your diamond like any other synthetic stone.

It's recommended to use water as lubricant to prevent stone loading.
