The Rasp is a related, but different, hand tool that has sharp bumps on its surface rather than straight ridges. CLASSIFICATION Files are classified according to several attributes. One is the cross-section of the shaft, which may be flat, round, half-round, square or triangular. Another is the size of the ridges, which can range from rough, coarse and bastard (meaning intermediate) to second-cut, smooth and dead smooth. A single-cut or mill file has one set of parallel ridges, while a cross-cut or double-cut file has a second set at an angle to the first. In Swiss-pattern files the teeth are cut at a shallower angle. SEE ALSO File (metalwork) |
