Safety pins are often seen as basic household items, yet their design includes a small feature many people never notice: a tiny hole near the clasp. At first, it may look decorative or accidental, but it serves a clear purpose. This opening allows a thread, fine cord, or lightweight string to pass through, expanding how the pin can be used beyond simple fastening.
When sewing or working with fabric, this small hole helps keep the pin stable. By threading it through the opening, the pin is less likely to twist, slide, or shift position, which is especially helpful on smooth or delicate materials. It also offers a practical way to store pins together. Sliding multiple pins onto a string through the holes keeps them organized, easier to locate, and safer to handle.
The same feature proves useful outside the sewing room. In everyday or outdoor situations, the hole makes it possible to attach a safety pin to a keyring, lanyard, or bag. This keeps it readily accessible for quick clothing adjustments, simple repairs, or temporary fixes when tools are limited and time matters.
Over the years, safety pins have earned their place in homes, travel bags, and emergency kits because of thoughtful details like this one. The tiny opening near the clasp is a reminder that effective design does not have to be complicated. Sometimes, a small and subtle feature can make an ordinary object far more versatile than it appears.
