   Arkansas stones are natural, quarried mineral stones mined in the Ouchita Mountains near Hot Springs, Arkansas. They are special & unique stones related to flint & have a hardness a little greater than steel files. Due to their special crystalline structure, not only do Arkansas Stones sharpen but they polish at the same time, leaving a smooth surface on tools. They are fine grit stones & are mainly used for putting a final edge on your tools.
