What is the main function of aviation snips?

The main function of aviation snips is cutting sheet metal. These specialized shears are designed with sharp, durable blades that make it easy to cut through various thicknesses of metal sheets. Their unique design often features different cutting patterns (left-cutting, right-cutting, and straight-cutting), allowing for versatility in making precise cuts, curves, or straight lines. This makes aviation snips particularly valuable in metalworking and construction applications, where accurate cutting is essential for shaping and assembling metal components effectively. The other options, while related to metalwork, do not align with the primary purpose of aviation snips, which is to facilitate efficient and clean cutting of sheet metal.
