How to use

Boride stones should be used with one of these lubricants:

• Water 
• Soapy water
• Boride Bori-Lube
• 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 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:

• Saw strokes on the work surface
• Residues of lacquer
• Small chips at the corners and along the edges (no larger than 1 mm)

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.
