The top and bottom surfaces of the files are double-cut, which enhances their efficiency and effectiveness in material removal. This feature ensures that the files can handle a variety of tasks with ease and precision. 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
