What tool is used to shape nails during a manicure?

The nail file is specifically designed for shaping nails during a manicure. It works by gently smoothing and refining the edges of the nails to achieve the desired shape, whether it's square, round, or oval. Nail files come in various grits, which allow technicians to choose the appropriate level of coarseness for the task at hand. This makes it an essential tool for providing a polished and finished look to the nails.

Scissors are primarily used for cutting nail tips or trimming hangnails but are not suitable for shaping the overall nail. A cuticle pusher serves to push back and groom the cuticles, while a nail brush is used for cleaning under the nails and removing debris, but neither tool is intended for shaping the nail itself. Therefore, the nail file is the ideal and professional choice for this specific aspect of manicure.
