That “small round hole” on a nail clipper isn’t decorative—it actually has a few practical engineering and convenience purposes.
On most nail clippers, the hole is part of a simple but clever design:
1. Attachment point (the main purpose)
The most common reason is that it lets you attach the clipper to a keychain, lanyard, or grooming kit.
Nail Clipper is small and easy to lose, so the hole helps people keep it:
- On keys
- In travel kits
- Attached to toiletry bags
2. Part of the lever mechanism
On many clippers, the hole is also connected to how the lever arm pivots.
The lever is pressed down to increase force, and the hole helps:
- Hold the pivot pin in place
- Allow smooth folding and unfolding
- Keep the design compact and stable
3. Manufacturing and assembly
In some models, the hole is also useful during production:
- Helps align parts during assembly
- Allows automated machinery to hold or position the clipper
- Reduces material while keeping strength
4. Bonus use (less common)
Some people use the hole for:
- Hanging the clipper in bathrooms
- Attaching small chains or nail kits
- Storing multiple grooming tools together
