DIAMOND CUTTER
Diamond cutter has this name because it was originally made with a diamond. It has a “T” shape and at the top in the middle there is a stone with a very sharp and strong point. It is used to work on what has been glaze fired to scratch off dirty marks and lumps and to force a small indent, which is useful when drilling holes into glazed work, as it stops the drill from slipping.
