What is the grit size for each grade of Arkansas Stone? Arkansas Novaculite stones are classified by specific gravity and not the size of the grain. The grain of the silica crystals that form Novaculite are essentially the same size, 3-5 microns, whether the stone is classified as Soft Arkansas or True Hard Arkansas. Using Specific Gravity Testing, we measure the density of their stones, that is the compactness of the grains bonded together. Therefore the harder stones would then have more grains than the softer stones. Since the grit size of Arkansas Novaculite does not widely vary, it is difficult to compare it with the grit sizes of man-made stones. Grit measurement standards for traditional man-made stones vary internationally. By U.S. grit standards, genuine Novaculite most closely relates to the 600-1200 grit size. 2. Do I need to lubricate my whetstones? What should I use? Wood Tech recommends that you use honing oil, a light mineral oil, to lubricate your stones during the honing process. Honing oil does more than serve as a lubricant, it also suspends the steel shavings from your knife and prevents them from clogging the pores of your whetstone. Whetstones should be cleaned after each use by rubbing a liberal amount of honing oil onto the stone and then wiping the excess honing oil away with a clean cloth.
