PSI Texas State Board Nail Tech practice exam

The inability of blades to be used for removing a callus from the foot stems from the fact that their use can pose significant safety risks and potential legal issues. Blades can lead to cuts or injury because they are sharp and meant for more invasive procedures. In many states, the use of such sharp tools is strictly regulated or prohibited in non-medical settings like salons.

In contrast, files, scrapers, and emery boards are designed specifically for callus removal and are generally safer. These tools gently abrade the thickened skin without the risk of cutting, making them suitable for use in nail care and pedicure practices. They provide an effective means to smooth out calluses without adding the risks associated with using blades.
