This Friedrich Dick checkering hand file, also called a texturing file, is ideal for cutting decorative serrations on bezel edges, for creating florentine-style finishes, and for checkering—cutting long, parallel lines, then cutting criss-crossing lines at angles up to 90° to form a diamond-like pattern in the metal. It features teeth arranged in parallel lines along the length of the file on the top and bottom surfaces. The edges are smooth, preventing marring or metal removal from surfaces adjacent to the work area.
This file has a German cut #2; German-cut files are graded by the number of teeth, counting teeth parallel to the long axis of the file. German cuts start coarser than Swiss and go finer, offering more increments for more precise cutting. In all cut styles, the higher the number, the finer its cut.
Hand files, also called 'full-size' files, feature a larger cutting surface that is longer and wider than other file types and are ideal for fast, efficient removal of material from the workpiece for initial shaping, for smoothing and, in finer cuts, for finishing. These files have a narrow, tapered tang intended to be secured into a handle (available separately) that provides comfort and control of the file when in use.
Among the finest jewelers' files in the world, Friedrich Dick files are made of tough chrome/tool steel alloy and precisely machined to yield sharp corners and fine points. These files have deep-cut teeth that provide efficient, uniform stock removal; they are 66–67 HRC hardness for exceptional service with minimal care.
