Rh Preyda 100% natural Arkansas stones are made from Novaculite- the ultimate sharpening stone.
Quarried in the Ouachita Mountains, near Hot Springs, Arkansas, Novaculite is not found anywhere else in the world. The unique cryptocrystalline structure of Novaculite allows the stone to retain its effective abrasion characteristic and shape. Sharpening stones are composed of 99.9% pure silica. What makes Novaculite so unique is it’s ability to remove less material than other abrasive products. Because the stone is naturally so durable, it is able to perform for an extended period of time and never require lapping or flattening.
