What is the main function of a nail file?

The primary function of a nail file is to shape and smooth the nail edge. Nail files come in various grits and materials, allowing technicians to refine the edges of the nails to a desired shape, whether it be square, round, or oval.

Using a nail file effectively is crucial in nail technology, as it helps to prevent snagging or breaking by ensuring that the edges are smooth. This aids in the overall aesthetics of the nails and contributes to the health of the natural nail by minimizing rough edges that could lead to peeling or injury.

While other tools and products may assist in painting, buffing, or cleaning nails, the specific task of shaping the nail edge is where the nail file excels, making it an essential instrument in nail care and enhancement.
