General description The Faithfull Diamond Sharpening Stone Kit is ideal for quick, easy, and effortless sharpening of any blade and many other tools. Its double-sided 8mm thick metal stone is electroplated with monocrystalline diamond in two grits, 400G Coarse and 1000G Fine. Each side can be easily accessed by simply releasing the stone from the docking station and turning it over. Unlike traditional abrasive sharpening stones, this diamond stone remains absolutely flat and will not groove over time, ensuring consistent straight edges on precision cutting tools such as wood chisels and plane irons.
