Tin snips are designed to cut thin sheet metal, using hardened blades and leverage similar to scissors to shear through metal like tin, aluminum, or copper sheets. This makes them ideal in metalworking, roofing, and ductwork where clean, precise cuts are needed in metal material. They aren’t meant for cutting wood or drilling holes, which require different tools, and while you might tidy up a rough edge after cutting, tin snips themselves are for making the cut, not smoothing.
