What is another name for a nail file?

The correct answer is emery board, which is a specific type of nail file made from a thin piece of cardboard or plastic that is coated with emery, a material used for sanding and smoothing. Emery boards are commonly used in nail care to shape and smooth the edges of nails, making them an essential tool in both professional and at-home nail grooming.

While other options might seem related to nail or foot care, they serve different functions. A file board is a more general term that does not specifically refer to nail grooming. A nail buffer is used to polish the surface of the nails rather than filing them. A pumice stone is primarily used for exfoliating dry skin on feet, not for filing nails. Understanding these distinctions is crucial for effective nail care practice.
