Which of the following is primarily used for cutting metal sheets?

Metal shears are specifically designed for cutting metal sheets and are optimal for this purpose due to their sharp blades and shearing action. They can effectively cut through various thicknesses of metal quickly and cleanly, making them a preferred tool for tasks that require precision and efficiency in cutting metal materials. The design of metal shears allows for a straightforward operation that minimizes distortion or damage to the surrounding area of the cut, which is crucial when working with metal sheets.

In contrast, a chisel is more commonly used for shaping or carving materials rather than making straight cuts, while a copper cutter is specialized for cutting copper pipes rather than sheets. An angled grinder, while versatile and powerful, is typically used for grinding, polishing, or cutting hard materials but is not specifically designed for cutting metal sheets cleanly and accurately. This distinction highlights why metal shears are the most suitable option for this task.
