Great for woodcarvers, woodworkers, machinists and home hobbyists, these ceramic sharpening bench stones offer a traditional shape to effectively hone wider edge tools such as carving tools, plane irons, wood chisels and large blades. Using the medium grit stone first and the fine grit second will produce a razor sharp edge. Ceramic stones require no water or oil and will experience little or no wear over time. Each comes in a heavy duty ABS box and can be used in or out of its box. The box has a lid and non-skid rubber discs on the bottom. Both the medium and fine grit stone are shown; however these are sold individually. Each stone size is 1/2" x 2" x 8".
