At what angle should a nail file be held when shaping nails?

Holding a nail file at an angle of approximately 45 degrees is ideal when shaping nails. This angle strikes a balance between effectively shaping the nail while minimizing the risk of damaging the nail bed and surrounding skin. A 45-degree angle allows for better control and precision, enabling the technician to file the nail in a smooth, even manner.

At this angle, the filing motion can be directed along the natural curve of the nail, promoting a more attractive and well-defined shape. Using a steeper angle, such as 90 degrees, could create blunt edges and increase the likelihood of splitting or tearing the nail. On the other hand, using a much shallower angle, like 15 degrees, would not provide adequate pressure or surface contact for effective filing. Therefore, the 45-degree angle is optimal for both functionality and safety during the nail shaping process.
