The Spyderco Benchstone is made from ultra-hard alumina ceramic material, and is used like a traditional sharpening stone, without the need for oil or water. Its broad, flat surface is ideal for putting a high-performance finished edge on woodworking tools and all types of knives and is easily cleaned with household cleanser, a scouring pad, and water.
This 2"X8" stone comes in a polymer case with non-skid rubber feet.
