The sharpening stones are made from aluminum oxide and are rock-solid. As such the stones quickly remove material and hardly wear out. Boride states that the T2 collection is the best collection to sharpen stainless steel. You can, however, also sharpen other types of steel with these sharpening stones. You can use the sharpening stones with water or sharpening oil. Do make sure, however, that if you use sharpening oil once, you always need to use sharpening oil! Water is not as effective in sharpening which has already been used with sharpening oil.
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 T2 is recommended for working with stainless steel.
