Why Nail Clippers Have That Small Circular Hole

While not officially recommended, it can help with smaller or slippery clippers. Historically, the modern nail clipper was invented in the late 19th century and evolved through thoughtful design improvements. The tiny hole made it portable in an era when bathrooms were not common, allowing people to carry grooming tools conveniently.

Today’s nail clippers often include added features like nail files, bottle openers, or small knives. That small circular hole may seem like a minor detail, but it demonstrates how simple design elements can make a big difference. Even ordinary tools can be surprisingly versatile when designed with functionality in mind.
