The primary purpose of the free edge of the nail is to:

Explanation:
The free edge is the part of the nail plate that extends past the fingertip. Its main role is to protect the fingertip (and the nail bed) from injury by acting as a shield against trauma. Growth happens at the nail matrix beneath the cuticle, so the free edge doesn’t drive how nails grow. While nails can assist with gripping objects to a small extent, that’s not their primary purpose. Circulation isn’t controlled by the free edge; blood flow is handled by the body's vascular system.
