True or False: The higher the grit number on an abrasive, the smoother the surface it creates.

The statement is true because the grit number on an abrasive indicates the coarseness or fineness of the material. A higher grit number corresponds to a finer abrasive, which means it has more abrasive particles per square inch. This fineness allows for a smoother finish when used, as it removes less of the underlying material and polishes the surface rather than creating harsh scratches. For example, while a lower grit number (like 80) is ideal for removing a significant amount of product or shaping nails, a higher grit number (like 240 or above) is suited for finishing and polishing, resulting in a smooth, even surface. Understanding this principle is crucial for manicurists in choosing the right tools for different nail care applications.
