Unraveling the Mystery: The Hidden Function of Safety Pin's Small Hole
- •The safety pin, a common household item, has a small round loop at its bottom whose purpose is often unknown.
- •Invented by Walter Hunt in 1849, the modern safety pin's design includes a spring mechanism and a head/guard.
- •The circular coil at the bottom acts as a spring, creating tension to keep the pin securely closed and prevent accidental pokes.
- •The head or guard at the top safely secures the pointed tip, preventing injuries.
- •Walter Hunt sold the patent for only $400, unaware of its future multi-million dollar value.
Why It Matters: The small loop on a safety pin is a crucial spring mechanism, ensuring the pin stays closed and safe.
