American manufacturer of natural grinding stones from Arkansas. Stone mining takes place in the Ouachita Mountains. Arkansas sharpening stones are very durable and more effective at grinding than classic waterstones. Due to its high hardness, it rarely requires lapping or leveling. Arkansas stones consist of novaculite, which is microcrystalline 99.9% pure silica. As these are natural stones, their grain size cannot be precisely determined. The types of stones varies from Soft Arkansas (grit size 400 - 600), Hard Arkansas (grain size 800 - 1000), Black Arkansas (grit size 2000 - 3000) to the rare Translucent Arkansas (grit size 8000 - 10000). When grinding on Arkansas natural stone, honing oil should be used. Arkansas whetstones are therefore also called oil stones. The extraction of novaculite has been going on since prehistoric times, and today the stones are extremely valued for their versatility and durability.
