Boride Recommended Stone Set for KME



Boride Stone Set is used for sharpening knives on KME or Hapstone knife sharpeners. All stones are made of aluminum oxide.

Boride stones should be used with one of these lubricants:

  • Water
  • Soapy water
  • Boride Bori-Lube
  • The water solution of dipropylene glycol
  • WD-40 (for experienced users only)
  • Refined olive oil (for experienced users only)
  • Oleic aсid (for experienced users only)

In case of using the water as a lubricant, soak the stone in water for 1-2 minutes. In case of using the oil, put a small amount (1-2 drops) of honing oil on the stone’s surface and spread it evenly over the stone with a finger. If the stone absorbs the honing oil, use a larger amount of oil.
