What happens when a nail file has a lower grit number?

It becomes more aggressive
It becomes less aggressive
It becomes smoother
It becomes less durable

The correct answer is: It becomes more aggressive

A nail file with a lower grit number is designed to be more aggressive in its exfoliating action on the nails. Lower grit files, typically ranging from 40 to 180, have coarser surfaces that can effectively shape and shorten the nails by removing more material quickly. This makes them suitable for tasks like quick filing or shaping of thick or strong nails. Conversely, a higher grit number signifies a finer texture, which is used for smoothing the surface of the nail after the initial shaping. While lower grit files can be used to start a nail shaping process, higher grit files are utilized to finish and polish the nail to achieve a smooth and refined appearance.
