Which tool is typically used for shaping nails during a manicure?

The nail file is specifically designed for shaping and refining the edges of the nails during a manicure. It is useful for smoothing rough edges and achieving the desired nail shape, whether it be square, oval, or round. The texture of the nail file allows it to effectively remove any length and create a clean finish without causing damage to the nails.

Other tools like the cuticle clipper are used for trimming excess or overgrown cuticles, and while important, they do not shape the nails themselves. The nail brush is utilized for cleaning under the nails or removing debris, rather than shaping. Polish remover is employed to take off nail polish, not for any shaping purpose. Therefore, the nail file stands out as the essential tool for shaping nails during a manicure.
