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.
