4” Soft Ark MultiForm Stone

Soft Arkansas is considered the coarsest of Arkansas sharpening stones, with a grit range of 400-600 that will provide the initial edge and first level of polishing. This Soft Arkansas Multiform Slipstone measures 4″ x 2″, with a round edge and a knife edge that taper from 1/2″ to 1/8″. It is used by carvers to shape, sharpen and hone V-tools, veiners and gouges, but it can put a nice edge on serrated knives as well. The stone comes in a protective case with a small bottle of light mineral oil. 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.
