What validates that a nail clipper is cutting properly?

A nail clipper that is cutting properly can be validated by applying a slight squeeze before cutting. This action ensures that the clipper is properly aligned and that the blades are positioned to cut effectively. When a technician applies a slight squeeze, it helps establish the right amount of pressure required to engage the blades fully and create a clean cut without causing unnecessary trauma to the nail. This technique also helps in minimizing the risk of splitting or tearing the nail, leading to a smoother, more controlled trimming process.

In contrast, the sound a nail clipper makes may not reliably indicate whether it is cutting correctly, as different materials and nail conditions can affect the auditory feedback. Visible pressure applied can also be misleading, as the pressure may not correlate directly to a clean cut. Lastly, the visual appearance of the nail after cutting can vary depending on techniques used, but it is not a direct indicator of whether the clipper is functioning optimally during the cutting process.
