Spyderco Benchstone Ultra Fine (306UF)

This ultra-fine, ultra-thin ceramic benchstone from Spyderco is used like a traditional sharpening stone, but does not require oil or water. Its extra-wide surface is ideal for sharpening woodworking tools and large knives and can be easily cleaned with household cleanser, a scouring pad, and water. It comes in a leather sleeve case that also serves as a non-skid pad while sharpening.
