d. Metal file
Files have forward-facing cutting teeth, and cuts most effectively when pushed over the workpiece. Drawfiling involves laying the file sideways on the work, and carefully pushing or pulling it across the work. This catches the teeth of the file sideways instead of head on, and a very fine shaving action is produced. There are also varying strokes that produce a combination of the straight ahead stroke and the drawfiling stroke, and very fine work can be attained in this fashion. Using a combination of strokes, and progressively finer files, a skilled operator can attain a surface that is perfectly flat and near mirror finish. The grooves in a file may became clogged during use, causing the file to lose its cutting ability and trapped shavings can scratch the work surface. A file card can be used to clean the file.
