Safety Pin

invention · everyday genius · fasteners

Spring and clasp design. A safety pin has a special spring mechanism that holds a clasp in place, creating a closed loop that covers the sharp point so you won't accidentally poke yourself.

Protects the user. The clasp acts as a shield over the pointy end of the pin, making it much safer to carry in your pocket or use on fabric without risk of getting hurt.

Simple but brilliant. Unlike a regular pin that's just straight metal, a safety pin twists back on itself to create its protective mechanism, which is why it's such a genius invention.

Holds things together. Safety pins fasten fabric, diapers, and other materials securely by going through layers and then the clasp locks it closed so it won't slip out.
