Have you ever wondered why there’s a small round hole near the end of a nail clipper? That tiny feature isn’t decorative — it has several practical and surprising uses that many people overlook.
First, the hole is designed to fit a small metal file or pin that some clipper sets include. This makes it easy to file and smooth rough edges after clipping, keeping nails neat and reducing the risk of snags. The compact design means you always have a filing tool right where you need it.
But the uses don’t stop there. Outdoors enthusiasts and DIYers have found that the hole can be used as a makeshift keyring attachment, allowing you to carry a clipper on your keychain for quick access. Some even thread a small cord through it to create a lanyard or hanging tool for travel kits.
Additionally, the opening can serve as a tiny nut or bolt holder in a pinch when working on small repairs, keeping the fastener steady while tightening or loosening screws with another tool.
So next time you pick up a nail clipper, remember that little round hole — it’s more useful than it looks!
