A square file is a metal tool with a rough surface used to remove small amounts of wood or metal from a workpiece. Ranging from six to 18 inches (15 – 46 cm) long, more or less, they generally have a narrow, pointed tang at one end designed for insertion into a removable handle. Square files are wider at their base, but rarely more than an inch (2.54 cm) or so, and taper to a narrow tip.

One of the most basic of hand tools, rasps have been found in archaeological digs dating as far back as 1200 – 1000 BC. The older rasps were made of brass, and more recent rasps were made of iron. Modern files are made of hardened steel with series of parallel ridges cut into them, or with industrial diamonds embedded in their surface.

A square file is only one of many that woodworkers and metalworkers will have in their toolboxes. Other popular files are mill files, round files, and three-square files, which are actually triangular. Many files are very small, sometimes no more than one-fourth of an inch (6.35 mm) wide at their widest point. These smaller files, often called needle files, usually replicate the shape of their larger counterparts, and a set of miniature files will often include a square file, a round file, a three-square file, among others. Needle files are very useful for detail work in both wood and metal, as well as for deburring metalwork.
