The innovative, multi-patented DuoSharp Bench Stone is a precision flat, two diamond surfaced sharpener guaranteed to provide consistent, even sharpening every time. Designed with a larger, wider diamond surface for sharpening a variety of edges, this 8" DuoSharp Bench Stone is an excellent counter and bench sharpener. This model also comes with a Bench Stone Base Accessory, and is equipped with two separate grits. On one side, there is extra-fine diamond (9 micron /1200 mesh) to polish and refine a razor edge after sharpening with a coarser diamond. On the opposite side, there is fine diamond (25 micron / 600 mesh) for initially honing the razor sharp edge. Thanks to the micronized monocrystalline diamond surface on each side as well, you can sharpen edges much faster and easier than conventional stones can. No messy oils are needed either, allowing you to sharpen dry or with water. Complete with a durable construction that will provide years of consistent performance and reliable service, professionals rely on the superior quality and versatility of DMT products for proper tool maintenance. Made in the USA.
