Honing Oil is highly refined oil and excellent for lubricating your stone when sharpening. Remember, you should never use an Arkansas Stone without some type of lubricant, or you will clog up the pores and it will not sharpen properly. Our Premium Honing Oil is a light mineral based oil for easy lubrication of the sharpening surface. The oil is used to float away particles of metal that accumulate on the surface of your sharpening stones.
