This Glardon Vallorbe® three-square (triangle) needle file is ideal for filing corners, edges, sharp angles and creases or folds; it is also useful for shaping the prongs on marquise- or pear-cut settings. The file has three flat sides of equal width that taper to a fine point, and the edges are rounded to protect adjacent structures as you file.
This file has a Swiss cut; Swiss-cut files are graded by the number of teeth, counting teeth perpendicular to the long axis of the file. In all cut styles, the higher the number, the finer its cut.
Needle files feature a miniature profile with a shorter cutting surface (typically about half their length) and round, narrow handles. These small files are ideal for working on fine details and in small areas of the workpiece; they're ideal when access and surface finish take priority over metal removal. Though they can be used as-is, securing the file in a handle (available separately) improves control for better precision and tool safety.
The first choice for most jewelers, Glardon Vallorbe® files are manufactured to the highest production standards, made in Switzerland of the finest heat-tempered chrome-alloy steel. The files are precision-ground to cut quickly and accurately and to last longer than just about any other file on the market.
