In nail care, what does a lower grit number on a file indicate about its abrasiveness?

  1. It indicates the file is less smooth and more abrasive.

  2. It represents a less aggressive file.

  3. It is used for fine finishing and smoothing.

  4. It is used for polishing nails.

The correct answer is: It indicates the file is less smooth and more abrasive.

A lower grit number on a file indicates a coarser, more abrasive surface. This means it is better suited for quickly reducing the length of the nail and shaping it, as it can remove material more effectively than a higher grit file. Coarse files are typically the first choice for filing down thick nails or creating a specific shape. The other options reflect misunderstanding regarding the grit system. A higher grit number is what signifies finer abrasiveness, which is intended for smoothing and finishing work on nails, while lower grit files are definitely not less aggressive; they are used when more material removal is needed. Similarly, polishing is associated with high grit files, not lower grit ones.
