The world's only deposit of whetstone grade material is located in a small area of the Ouachita Mountains in Arkansas. Silica deposits later known as novaculite were first discovered by American Indians. Traces still remain of their prehistoric efforts to quarry the rare stone for arrowheads and other tools. Present day mining efforts for sharpening stone material started there in the late 1800s. There are three different grades--soft, hard and extra fine. Colors in the different grades can vary from white to almost clear and many combinations in between. The Washita variety of soft Arkansas stone is the most unique soft stone known. It is the most recognizable with its swirl pattern of purple and white. There is only one known quarry that has this type of Arkansas stone. The Washita is the fastest sharpening, most durable soft stone that has been mined to date. With a very limited supply available, this stone is truly a novelty and should be had by anyone who is serious about sharpening.
