Smiths Diamond Retractable Sharpener

The Smiths Diamond Retractable Sharpener (brand part no. SP-51446) features a diamond-coated steel rod designed to sharpen straight and serrated blades with precision. Smiths applies multiple layers of medium-grit monocrystalline diamonds to provide efficient material removal while maintaining a refined edge. The reversible rod offers a tapered surface for serrations and a half-round surface for straight edges, and it adjusts to variable lengths for convenience. A built-in groove accommodates hook sharpening, while the compact, pen-sized design with a pocket clip allows easy everyday carry, retracting into the handle for protection when not in use.
