These files feature a consistent width and a tapered thickness, enabling precise flat filing. The top and bottom surfaces are double-cut, while both edges are designed to be safe. These pillar extra-narrow files, designed in the Swiss-pattern, offer flat filing with a consistent width and a tapered thickness, ensuring precise control The dual-cut top and bottom surfaces optimize material removal efficiency, while the protective safe edges prevent unintended marking of adjacent surfaces during operation This renders them a reliable option for precision tasks in firearms engineering and metallurgical alterations
