What is the free-edge of the nail?

The free edge of the nail is the part of the nail plate that extends beyond the fingertip and is not attached to the nail bed. It is the visible portion of the nail that can be trimmed or shaped. This area is typically more exposed and can be susceptible to wear and damage, making proper nail care important. The free edge plays a role in protecting the fingertips and enhancing the overall appearance of the nails.
