Norton Knife Sharpener Whetstone - Japanese Sharpening Stone with 4000 Grit Stone and Sharpening Stone Holder
Product Description The NORTON IM9 India fine-grit replacement oilstone for the IM313 sharpening system is made of aluminum oxide, suitable for sharpening and maintaining steel cutting edges; it produces durable, smooth-cutting edges and is preferred for close tolerances. The stone is prefilled with oil to save time and eliminate the need to presoak it prior to use. The oil prevents metal from bonding with the abrasive surface by flushing away dislodged abrasive and metal chips. This oilstone is commonly used to replace a stone in the Norton IM313 sharpening system, or as a bench stone, to restore cutting edges on straight-edged tools
