Many people have noticed the tiny round hole on a nail clipper, but few know it serves a real and practical purpose. The feature is designed to allow the clipper to be attached to a keychain, hook, or small ring, making it easy to carry and always accessible.
This small design detail helps keep grooming tools organized and prevents them from getting lost in drawers or cabinets. Some people also use the hole to hang the clipper near a sink, improve grip while trimming tough nails, or keep multiple clippers together on a single ring.
The feature dates back to early nail clipper designs from the late 19th century, when portability and convenience were essential. It’s a simple reminder that even the smallest details in everyday tools are often designed with a purpose in mind.
