The small round hole on many nail clippers is a leftover design feature that has a few possible uses, depending on the clipper style:
- Keychain attachment
The most common purpose today is to attach the nail clipper to a key ring, chain, or small lanyard so it is easier to carry and less likely to get lost. - Manufacturing and assembly
In some designs, the hole helps with attaching or positioning parts during manufacturing. - Storage and hanging
Some people use it to hang the clipper on a hook or store it conveniently. - Old multifunction designs
Older nail clippers sometimes included holes or openings as part of designs that supported additional tools or attachments.
Despite being a tiny feature, it remains useful because nail clippers are small objects that are easy to misplace, and the hole provides a simple way to keep them attached to something.
