What tool should be used to lift small bits of debris from the nail plate?

The use of tweezers to lift small bits of debris from the nail plate is the most appropriate choice because tweezers are specifically designed for precision handling of small objects. They allow for controlled movements to safely remove debris without causing damage to the nail or surrounding skin. The pointed tips provide the necessary grip to pick up tiny particles effectively, ensuring a clean and polished nail appearance.

Using a pusher is primarily intended for pushing back cuticles and may not be agile enough to retrieve small debris. A cuticle cutter is designed for trimming excess cuticle tissue, not for lifting debris. While a buffing block can smooth the surface of the nail, it is not suitable for lifting or removing debris. Therefore, tweezers are the best tool for this specific task, as they are tailored for such precision needs in manicure and nail care practices.
