Analysis:
Before there were zippers, buttons or other fasteners, our ancestors used large needles to tie their clothes together. But the needle also brings some problems. The sharp needle tip is very dangerous, and the needle is easy to slip.
About 4, years ago in Crete, someone made something that looked like a large safety pin that could be used to button clothes, thus finding an excellent solution for people to button clothes. This kind of green steel pin is bent over and buckled at one end to avoid the danger caused by the needle tip. Later designed pins also have a spring to make them firmly clamped.
Many ancient people-from Greeks and Romans to ancient British Celts-used old-fashioned safety pins. People usually wear these pins high, so they are brooches rather than pins. However, by the 19th century, people had forgotten the ancient safety pin until Walter Hunt invented the modern safety pin in 1849.
Hunter invented many small things, and most of these inventions were patented. Because patent applications require drawings, Hunter often owes money to the painter who painted them for him. He used the patent right of whatever he could do with an old piece of wire to settle the painter's debt. A painter named Richardson paid Hunter only $4 and bought the patent right of safety pin.
At the beginning of the 2th century, safety pins have been sold as very cheap and commonly used things, which are really insignificant compared with ancient bronze button needles. However, in modern times, the pin has undergone new changes. People have slightly modified the pin, made it into various ornaments, and made it popular.
