Most people use a safety pin without ever noticing the tiny circular coil near its hinge. While it may look like a simple decorative detail, that small loop plays a crucial role in making the pin safe, durable, and easy to use.
Step 1: Look at the Circular Coil
The small spiral at the base of the safety pin isn’t just for appearance. It’s a carefully engineered spring that gives the pin its flexibility and strength.
Step 2: Understand How It Works
When you open the safety pin, the coil twists and stores tension, much like a tiny spring. This stored energy allows the pin to snap back into its closed position securely.
