A single nail clipper can be used to trim both fingernails and toenails. However, it is important to choose an appropriate size and shape of the nail clipper that matches the thickness and curvature of the nails being trimmed.To use a single nail clipper, place the cutting head around the edge of the nail that needs trimming. Apply gentle pressure to the lever handle to bring the blades together, cutting the nail in a smooth and controlled manner. It is advisable to trim nails in small increments to avoid cutting too much at once.After each use, it is recommended to clean the nail clipper by removing any nail clippings and debris. You can use a brush or a cotton swab dipped in alcohol to sanitize the cutting head. Regularly inspect the blades for any signs of dullness or damage, and replace the nail clipper if necessary.

Safety Precautions: When using a nail clipper, exercise caution to avoid cutting the surrounding skin or damaging the nail bed. Trim nails straight across or with a slight curve to prevent ingrown nails. If you have any underlying nail conditions or concerns, consult a healthcare professional.
