8”x2x1 Hard Blk/Soft Combo Bench Stone           

This 8" x 2" x 1" Arkansas Combo Stone features Soft and Hard Black Arkansas Stones essentially glued back-to-back. If you need both or are undecided about which to buy first, now you can have both in one stone. Start on the Soft Arkansas (400-600 grit) side to create an edge and then switch to the Hard Black Arkansas (2000-3000 grit) to create a perfectly sharp edge. Stone can be used with or without lubrication, but we suggest light oil, which will keep the stone’s surface fresh and free from glazing that could potentially diminish the stone’s performance.
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.
