Boride CS-HD Narrow stones set

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. Boride stones are made of aluminum oxide, with the exception of CS-HD series stones, which are made of silicon carbide. All Boride stones are 6mm thick and are mounted on high quality aluminum blanks. Stones that are 6mm thick offer a longer life cycle than stock Edge Pro stones that are 3mm thick and are becoming a community standard.

Details

• CS-HD series stones are made of silicon carbide and are designed for the hardest steels (up to 63 HRC). It is advisable to use the CS-HD stone set to sharpen knives made of hard stainless steel or carbon steel. Use of CS-HD stones to sharpen knives made of soft steel is not recommended – this will cause the CS-HD stones to wear at increased rates. However, the coarse CS-HD stones (120 and 150 grit) are often used as a universal coarse stone and perform well in this role. CS-HD is the second most popular of the Boride series for Edge Pro sharpening.

How to use

Boride stones should be used with one of these lubricants:

• Water
• Soapy water
• Boride Bori-Lube

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 1mm)

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.
