The “small round hole” on the nail clipper has special

Nail clippers may look like a straightforward grooming tool, but the small round hole at the end actually has more than one purpose.

The most common reason for its design is to allow a keychain to be attached. This makes nail clippers easier to carry, harder to lose, and more convenient while traveling.

Some clippers are even sold with a small chain included. However, connecting them directly to a sturdy keyring is often more secure and long-lasting.

Interestingly, the hole isn’t just for storage. It can also serve practical functions around the house, making the clipper more versatile than expected.

For example, threading a thin wire through the hole allows you to bend or adjust the wire safely without putting your fingers at risk of cuts or scratches.

It can also be used as a guide for trimming delicate materials, such as cords, threads, or yarn, giving you more control compared to cutting freehand.

Though often overlooked, this tiny feature turns a simple nail care tool into a handy multi-use accessory—useful not only for grooming but also for small problem-solving tasks in everyday life.
