What should be done to remove rough edges and bevel nails?

The recommended method for removing rough edges and beveling nails involves using an upward stroke at a 45-degree angle. This technique helps to ensure a smooth finish while preventing damage to the nail plate. Using a 45-degree angle allows the file to glide smoothly over the edges, effectively smoothing out any roughness without creating additional damage or splitting the nail.

When filing, it's essential to use a smooth and controlled motion, which is facilitated by the upward stroke. This motion reduces the risk of tearing or chipping the nails compared to more aggressive filing angles or techniques.

The importance of this technique is also underscored by the fact that using a pointed file at any angle may not provide the desired control or effectiveness. Similarly, filing the edges in a downward stroke can lead to stress on the nail, potentially causing splits or breaks. Buffing with a smooth sponge serves a different purpose by polishing, rather than shaping, the nail, making it less effective for achieving the desired edge refinement. Thus, the upward stroke at a 45-degree angle is the ideal approach for this purpose.
