There may be a practical reason hiding in plain sight.
The tiny hole on your nail clipper isn’t necessarily a secret tool or a mysterious piece of engineering.
For many common designs, it is simply a clever attachment point that helps keep a small grooming tool portable and easy to store.
And sometimes, simple really is ingenious.
So, be honest: Did you already know what that little hole was for, or have you been using nail clippers for years without ever asking?
