The Hard Arkansas Stone is a super-fine stone that is satisfactory for the final edge on woodworking cutting tools & knives. Use a few drops of mineral oil to prevent glazing while sharpening. *Note* Grain on stones will vary from stone to stone. No returns based on grain configuration.
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.
