This is a "soft" Arkansas stone - you sprinkle water on it, lay the knife blade on it at about 30 degrees and try very gently to skim off a microscopic layer of the stone. Turn the knife over and repeat until razor sharp. A light pressure does it. Clean the stone with an oil or water-wet rag afterwards. The holder is cut from a solid piece of hardwood and is adapted from a drawing of an original by the well known military artist George Woodbridge. The stone is 6" long, 2" wide & 1" thick and fits tightly into its container. TEMPORARILY SOLD OUT!
