The innovative, multi-patented DuoSharp Bench Stone is a precision flat sharpener with two diamond surfaces, guaranteed to provide consistent, even sharpening every time. The 8" DuoSharp Bench Stone is an excellent counter and bench sharpener, featuring a larger, wider diamond surface for sharpening a variety of edges. This model comes with a Bench Stone Base accessory. It includes a coarse diamond (45 micron / 325 mesh) to quickly restore a neglected edge and a fine diamond (25 micron / 600 mesh) for a razor-sharp edge. Sharpening with diamonds is fast and easy; no messy oils are needed—sharpen dry or with water. Its durable construction ensures years of consistent performance and reliable service.
