The horn file (1) is used to work hard wood, horn, ivory or lead by friction. It is a metal straight or curved rod (15-25 / 0.5-3 / 0.5 cm) with deep parallel notches in the width, inserted into a short wooden handle of about 15 cm (2).
The tool can be distinguished from the rasp for wood, which has points. [MOT]
(1) Proper name unknown. Because the tool is widely used to process horn, we propose this name.
(2) See a special model that resembles an iron in ROUBO: 3 pl. 328.
