Stones for Sharpening, Grinding & Finishing
All sorts of tools can and need to be sharpened, ground or polished with various stones; gravers, screwdrivers, knives, shears, drill bits, scoring tools, tweezers, virtually anything which needs to have a razor-sharp style edge.
The coarseness of a sharpening stone is defined by its grit rating; lower rated stones are coarse and higher rated stones are smooth. Properly sharpening tools involves three steps: grinding, sharpening and polishing. Grinding shapes your tool, but will leave large imperfections and nicks using a coarse stone. Using a medium grit stone, sharpening gives a tool a sharp new edge. Finishing polishes the tool and removes any small-scale surface imperfections when using a high grit sharpening stone.
