Vintage Folding Metal Nail File with Celluloid Handle

This item is a mid-20th-century folding pocket nail file. It features a hardened stainless steel file blade with a dual-sided cross-hatched abrasive texture and a pointed tip designed for nail cleaning. The handle is constructed from a creamy, off-white synthetic material, likely celluloid or an early phenolic resin (Bakelite variant), common in vanity accessories from the 1930s through the 1950s. The handle scales are secured by a single metal pivot pin that allows the blade to rotate 180 degrees. A distinctive semicircular cutout resides in the handle to facilitate easy deployment of the file blade. Regarding condition, the metal shows minor surface oxidation and light scratching consistent with age and occasional use. The handle material exhibits a warm aged patina but appears free of major cracks or 'celluloid rot,' though there is subtle darkening around the pivot pin. The construction is utilitarian but solid, typical of mass-produced personal grooming tools distributed by pharmacy brands or included in travel vanity kits. No specific maker's mark is visible in the current orientation, though such items were frequently produced in cutlery centers like Sheffield, England, or Solingen, Germany.
