What is the primary use of a nail file?

The primary use of a nail file is to shape and smooth the edges of the nails. When performing manicure and pedicure services, shaping the nails is an essential step to achieve a desired length and contour. A nail file is specifically designed to gently grind down and refine the edges of the nail, creating a neat and polished appearance. Its abrasive surface allows for precise control over the nail's shape, which is critical for both aesthetic purposes and preventing snagging or breakage in the future. Although nail files can be associated with other tasks, such as smoothing edges after polishing, their main function is unequivocally focused on the shaping and smoothing of the nail itself.
