The Secret Behind the Safety Pin's Loop: A Design Masterpiece You Never Knew

• The safety pin, known as fibulae in Latin, has origins dating back to the Bronze Age in Europe.
• Walter Hunt invented the modern safety pin in 1849, creating a spring-loaded system from a bent wire.
• Early designs included a North European method with two separate parts and a Central European method using a single wire with a spring.
• The loop or coil at the base of a modern safety pin acts as a crucial spring mechanism.
• This spring creates tension, holding the pointed end firmly and preventing accidental opening or injury.

Why It Matters: The safety pin's simple loop is a vital spring, ensuring its functionality and safety through tension.
