What does a metal rasp do in the nail care process?

• A. Files in multiple directions
• B. Is used to trim toenails
• C. Files in one direction
• D. Is a type of foot file

Answer: (C)

A metal rasp is specifically designed for filing nails in one direction, which helps to prevent damage to the nail and reduces the risk of splitting or tearing. This controlled filing technique provides more precision and can create a smoother edge on the nails.

In contrast, while other options mention functions that might seem relevant to nail care, they do not accurately describe the primary purpose of a metal rasp. For example, files that operate in multiple directions can cause rough edges and weaken the nails, which is not the intention behind using a metal rasp. Similarly, the metal rasp is not primarily designed for trimming toenails or classified strictly as a foot file. Its focus is on the filing technique, which is why the correct answer emphasizes its function of filing in one direction.
