The small round hole on a nail clipper isn’t just design—it was made to keep it from getting lost.
In the past, people carried grooming tools everywhere, so the hole let them attach clippers to chains, keyrings, or hang them on hooks. This kept them secure and easy to find.
Today, it still works for keychains or storage—but it’s really a smart, simple feature from a time when tools were built to last and stay with you.
