Who invented the safety pin?
Safety pin
Walter Hunt
American mechanic Walter Hunt is regarded as the inventor of the safety pin that bears resemblance to those used today. The safety pin included a clasp that covered the point and kept it from opening, and a circular twist at the bend to act as a spring and hold it in place.[3]  Charles Rowley (Birmingham, England) independently patented a similar safety pin in October 1849,[4] although the company no longer makes these.
