The Hidden Purpose of a Safety Pin's Hole: A Design Secret Revealed
- •Safety pins, known as fibulae in ancient times, originated in Europe during the Bronze Age.
- •The modern safety pin was invented by Walter Hunt in 1849, using a single bent wire with a spring-loaded mechanism.
- •Early Northern European pins had two parts, one with a hole for fastening, a complex design.
- •Central European, Greek, and Italian pins were closer to modern designs, made from a single wire with a central spring.
- •The wire at the base of a modern safety pin forms a loop or coil, acting as a spring to create tension and hold the sharp tip securely.
Why It Matters: The safety pin's design, including its spring mechanism, is a clever engineering solution for secure fastening.
