An engineer's file is a hand tool used to shape, smooth, or finish materials like metal or wood. It consists of a hardened steel bar with a series of ridges or teeth cut into its surface, allowing for material removal through abrasion. Files come in various shapes and sizes, each designed for specific applications, such as flat, round, or half-round. The effectiveness of a file depends on its coarseness, with coarser files removing material faster, while finer files provide a smoother finish.
