Which tool is most commonly used for shaping nails?

The most commonly used tool for shaping nails is the nail file. This tool is specifically designed to gently file and shape the edges of the nails into the desired form. Nail files come in various grits, allowing for different degrees of smoothing and shaping, which is essential for achieving a clean and polished look. The ability to refine the shape of the nail—whether it be square, oval, or any other style—makes the nail file indispensable for nail technicians.

While other tools have their utility, they serve different primary functions. A nail buffer is used mainly to smooth and shine the nail surface, enhancing the overall appearance but not shaping it. A nail clipper is primarily meant for shortening nails rather than shaping them, and a nail art brush is designed for creating designs and applying polish rather than handling the basic shaping of the nail structure. Therefore, the nail file is the most versatile and essential tool for shaping nails in a professional setting.
