RH Preyda Arkansas Stones
RH Preyda’s 100% natural Arkansas stones are made from Novaculite quarried in the Ouachita Mountains, near Hot Springs, Arkansas. The unique cryptocrystalline structure and density are the keys to the stones retaining their effective abrasion characteristics and shapes with what amounts to minimal care.
Arkansas Stones and Grit.
Arkansas stones are graded on hardness and not grit, but grit is an easier concept for most to grasp so a grit equivalent is offered as a comparison to synthetic stones. The grit range of natural stones will vary, so in most cases a range of grit is offered – again as a comparison to synthetic stones.
