Who invented the safety pin and when?

The safety pin was invented by Walter Hunt, an American mechanic, in 1849. Hunt created the safety pin as a simple, yet effective, way to fasten materials together. He patented the design, which included a spring mechanism, a clasp to hold the pin in place, and a protective cover to prevent accidental pricking. The safety pin quickly became a common household item, used for everything from fastening clothing to craft projects. Hunt’s invention is still widely used today in various forms for securing things safely and efficiently.
