Boride Sharpening Stones are used for sharpening knives on Hapstone Pro sharpeners. Boride offers a wide range of stones with different performance values and different rates of wear.
Orange EDM series stones are made of aluminum oxide and were originally intended for the treatment of metal after the electric spark machining (EDM). These very popular stones have medium grit for sharpening knives.
Boride stones should be used with one of these lubricants:
In case of using the water as 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 larger amount of oil.
Boride Stones may have the following minor defects:
All these defects will be eliminated during preparation of the stone. The majority of sharpening stones requires preparation, and Boride stones are no exception. Additional lapping can be performed by customer to improve sharpening quality. We recommend to use loose silicon carbide powder or diamond lapping plate.
