The DMT DuoSharp diamond sharpening stone is available in 8-inch (20 cm) and 10-inch (25 cm) sizes, as well as in various versions such as the standard version, the Plus version with an additional diamond surface for small tools, and the particularly durable hardcoat version. The included base ensures safety and precision during the sharpening process by guaranteeing a non-slip grip on smooth surfaces thanks to its rubberized feet, and by allowing for easy guidance of the stone over larger workpieces thanks to a handle on the underside.
