The ideal angle for holding a nail file during use is 45 degrees. This angle strikes a balance between effectively shaping the nail while minimizing the risk of damaging the nail bed or the surrounding skin. When the nail file is used at this angle, it allows for smooth, controlled strokes that can follow the natural curve of the nail.

Using a more acute angle, such as 30 degrees, may not provide enough leverage and could lead to uneven filing, while a more obtuse angle like 60 or 90 degrees may be less effective as it could create excessive pressure or dragging on the nail, potentially leading to splits or breaks. Therefore, holding the nail file at a 45-degree angle optimizes the filing process for both precision and safety.
