That small round hole at the base of your nail clipper serves three distinct practical functions:
-
Keychain Attachment: It allows you to thread the clipper onto a key ring, lanyard, or travel pouch so it stays accessible and doesn’t get lost in a bag.
-
Lever Retainer Swivel Pin: In many standard clipper designs, the hole aligns with the central pivot post. During assembly, it acts as the mounting anchor that holds the flipping top lever, pin, and dual cutting blades securely together under tension.
-
Manufacturing & Plating Vent: During industrial production, factories use that hole to suspend the steel clippers on wire hooks while dipping them into anti-corrosion chrome or nickel plating baths.
