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 6 mm thick and are mounted on high quality aluminum blanks. Stones that are 6 mm thick offer a longer life cycle than stock Edge Pro stones that are 3 mm thick and are becoming a community standard.

AS-9 series stones are made of aluminum oxide and were originally intended for the treatment of metal after electric spark machining (EDM). Due to their excellent performance and weak leading, AS-9 stones were soon in demand for sharpening knives. AS-9 320 grit is included in one of the Boride stone bundles.
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. Orange EDM 600 grit is included in one of the Boride stone bundles.
Golden Star series stones are made of aluminum oxide with grain that is strictly controlled. Designed for medium-hard steel, they are high performance stones. The stones do not require a long soaking. Boride recommends Golden Star series stones as the best choice to work with high carbon steel. Golden Star 800 grit and 1000 grit are included in Boride stone bundles.
AM-K series stones are made of aluminum oxide and have an average hardness. AM-K 220 grit is in great demand for the rough sharpening of knives and is included in all Boride stone bundles.
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.
PC series (Polisher's Choice) stones are made of aluminum oxide with grain that is strictly controlled and a special bond. As you might have guessed from the name of the series, these stones are designed for finishing operations with fast removal. PC 1200 grit is very popular as a finishing stone and is part of Boride stone bundles.
T2 series stones are made of aluminum oxide and use a very strong bond. As a result, these stones are high performance and their wear rate is below average. Boride recommends T2 at the best series for working with stainless steel. The T2 series is the most popular among all Boride series for Edge Pro sharpening. Many customers buy entire sets of the T2 series. T2 400 grit is included in Boride stone bundles.
RUBY series stones are made of aluminum oxide and are high performance stones designed for roughing work. They are available only in coarse grain. RUBY 150 grit is in great demand for coarse sharpening and is included in Boride stone bundles.
