1. Attaching to a Key Ring
The most common purpose of the hole is to allow you to attach the nail clipper to:
- A key ring
- A keychain
- A travel kit
- A backpack or toiletry bag
This makes the clipper easy to carry and less likely to get lost.
2. Hanging for Storage
The hole also allows the clipper to be hung on:
- A hook
- A pegboard
- A bathroom organizer
This keeps it clean, dry, and easy to find.
3. Part of the Lever Mechanism
On many nail clippers, the hole is part of the rotating lever’s design. It helps the lever fit securely over the small metal pin that provides the cutting force. While the hole itself isn’t what makes the clipper cut, it is part of the mechanism that allows the lever to work properly.
Other Useful Features You May Have Overlooked
Many nail clippers also include:
- A built-in nail file for smoothing rough edges.
- A nail cleaner (the pointed tip on some files) for cleaning beneath the nails.
- A curved cutting edge designed to follow the natural shape of the fingernail.
Tips for Using Nail Clippers Safely
- Clip nails when they are clean and slightly softened, such as after a shower.
- Avoid cutting nails too short, as this can increase the risk of pain or infection.
- Clean the clipper regularly with soap and water, and disinfect it occasionally with rubbing alcohol.
- Don’t share nail clippers, especially if someone has a nail infection.
Bottom Line
The small round hole isn’t a hidden “secret feature”—it’s mainly there to attach the clipper to a key ring or lanyard and, on many designs, to support the lever mechanism. It’s a simple design detail that has remained useful because it makes nail clippers easier to carry, store, and use.
