safety pin

A safety pin is a fastener consisting of a pin with a clasp and a guard that covers its point when fastened. This design ensures it can be used to secure clothing or papers without exposing the sharp end. The earliest known use of the safety pin dates back to 1847. Pins have a long history, with ancient Egyptians, Greeks, and Romans using them for fastening clothing, often in decorative forms. By the late 15th century, manufacturing pins from iron wire became common, and by the 19th century, automated pin-making machines significantly increased production efficiency.12
