Most people never notice the tiny hole in a nail clipper, but it’s there for a reason. This small design detail allows the clipper to be attached to a keychain or lanyard, making it easy to carry and harder to lose—especially useful for travel or everyday convenience.
In some designs, the hole also helps the nail file rotate and lock securely, improving grip and control while filing. It’s a simple, low-cost feature that adds versatility without complicating the tool, proving that even everyday objects can hide smart, thoughtful engineering.
