Glardon-Vallorbe Crochet Precision Files (LP1230) are tapered in both width and thickness, making them well suited for filing in recesses, grooves, and tight areas where standard flat files cannot reach. Measurements are taken at the thickest point of the file. Lengths are measured from the point where the teeth begin to the end of the file — a 6" file, for example, measures approximately 8½" overall tip to tang, but is classified as a 6" file. Tang length is not included in the stated measurement.
Manufactured in Switzerland to precise production standards, these files combine machine cutting with hand craftsmanship to deliver accurate, fast-cutting, and long-lasting performance across all metals. Made from finest heat-tempered chrome alloy steel, they offer the balance, feel, and action demanded by professional jewelers, metalsmiths, and watchmakers. Formerly distributed by Grobet USA under the Grobet Swiss brand name.
