Who invented the safety pin?
Safety pin was invented by the Myceaneans on the Greek Peloponnesus between the 14th and 13th Century BC, and is considered an early precursor to a safety pin since they were used in a similar manner. Fibulae were used by Greek women and men to help secure tunics. 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. Charles Rowley
