Needle File Set: Six Small Files Cut by Hand

Needle files are small files for fine work, where a good finish matters more than speed, sold in sets of shapes: pillar, half round, barrette, square, round and triangular. They are made like any file, only smaller and with finer teeth: forged, annealed, cut tooth by tooth with a chisel, and hardened in brine. The picture: our diagram, six tapered needle files and their cross-sections.
