For serious metalworkers, jewelers, and craftspeople who demand precision, this Glardon Vallorbe Swiss needle file is the real deal. Made in Switzerland from premium chrome alloy steel that's been heat-treated using a special process to maintain razor-sharp teeth longer than ordinary files. The half-round shape is tapered in both width and thickness, coming to a rounded point that's perfect for getting into tight spaces and curved surfaces. The #00 extra coarse cut chews through material quickly but still leaves a surprisingly smooth finish. At 6-1/4 inches including the handle, it's the perfect size for detailed work without being too small to control properly. What's impressive is how well it handles all types of metals - from soft brass and copper to tough steel and even platinum for jewelry making. The teeth are cut on both flat sides, giving you multiple working surfaces in one tool. If you're tired of cheap files that dull quickly or leave rough marks, this professional-grade file will make you wonder how you managed without it. The quality is immediately noticeable from the first stroke - smooth cutting action that removes material efficiently without clogging. A must-have for any serious workshop!
