About this product
This triangular diamond sharpening stone from Faithfull offers three working faces in one compact tool, covering the full sharpening process from coarse reshaping to a fine finish. The 150 and 325 grit sides handle damaged or very dull edges, while the 1200 grit side produces a polished finish. It comes with a plastic base fitted with non-slip pads at each end for stable, controlled use. The diamond surfaces are suited to carbon steel, HSS and tungsten carbide tools, and can also be used to abrade glass, ceramic tiles and porcelain. It can be used dry or with water as a lubricant, making it suitable for knives, scissors, chisels, plane blades, cutting blades and TCT router bits.
