A piercing saw, also called a jeweler's saw or jeweler's blade, is a saw commonly used in jewelry making to cut sheet metal, generally softer metals, since its fine blades are delicate. Like a coping saw, it holds its blade under tension in a metal frame, and because the fine blades break often, the frame can be adjusted to reuse broken pieces of blade at a shorter length; frame throat sizes typically range from 50 to 200 millimeters, and blades come in a range of thicknesses chosen to suit the metal and the work being done.
