Which instrument is used for trimming the cuticle?

The nipper is specifically designed for trimming the cuticle due to its sharp, pointed edges that allow for precision and control. This tool can effectively remove dead or excess skin around the nail bed without causing damage to the surrounding live tissue. Nippers have a unique design that provides leverage and allows for a clean cut, making them ideal for this particular task in manicure and pedicure services.

Scissors, while sharp and capable of cutting, are not typically used for cuticle work as they do not provide the same level of precision or control. Clippers are primarily designed for cutting nails rather than delicately trimming cuticles. A file is used for smoothing the edges of nails and shaping them but does not cut or trim skin. Thus, the nipper is the correct tool for trimming cuticles effectively and safely.
