Natural whetstone produced in Arkansas, United States, boasting world-class quality.

Arkansas stones are natural sharpening stones produced in the Ouachita Mountains of Arkansas, United States. This raw material is called novaculite, a sedimentary rock composed of microcrystalline quartz, recognized as a type of chert that has recrystallized, and it consists of over 99 percent pure silica. Novaculite is a sharpening stone that is almost nonexistent outside the Ouachita Mountains of Arkansas, making it the finest polishing stone in the world. **Grades of Arkansas Stones** Soft Arkansas Stone (medium grit, specific gravity 2.25–2.30) Hard Select Arkansas Stone (fine grit, specific gravity 2.30-2.45) True Hard Arkansas Stone (extra fine grit, specific gravity 2.5 or higher) Black Hard Arkansas Stone (extra fine grit, specific gravity 2.5 or higher) Translucent Hard Arkansas Stone (extra fine grit, specific gravity 2.5 or higher) Arkansas stones and novaculite are classified by specific gravity rather than grain size.

basic information

Even if the whetstone is classified as soft Arkansas or true hard Arkansas, the quartz grains that form novaculite are essentially about 3-5 microns in size. A specific gravity test of the whetstone is conducted to measure the density of those stones (the fineness of the bonded grains). As a result, true hard Arkansas whetstones will contain more quartz grains than soft Arkansas whetstones. In other words, hard whetstones have fewer voids, while soft whetstones have more voids. The grain size of Arkansas novaculite is nearly uniform, and the grade varies with the amount of voids. Therefore, it becomes very difficult to compare the grain size of Arkansas whetstones with that of artificial whetstones. The measurement standards for the grain size of conventional artificial whetstones vary by country. According to the grain size standards in the United States, pure novaculite is said to be closest to #600-#1200, while in Japan, it is said to be #6000.
