An emery board is primarily used for what purpose?

An emery board is primarily designed for shaping and beveling nails. This tool is typically made from a thin piece of wood or cardboard coated with abrasive material, which allows for effective filing of the nail edges to create a smooth finish and desirable shape. Shaping nails is a fundamental part of manicuring, as it contributes not only to the aesthetics of the nails but also to their health and strength by preventing snags and breaks.

While options involving pushing the cuticle, painting nails, or decorating nails are relevant to the manicuring process, they each require different tools and techniques. For instance, pushing the cuticle is typically performed using a cuticle pusher or an orange stick, while painting and decorating nails involve nail polish and art supplies. Thus, the correct application of an emery board is specifically focused on shaping and beveling nails, highlighting its unique and primary role in the manicure process.
