Boride AS-9 Thick F150

Boride Sharpening Stones are used for sharpening knives on Hapstone  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.
