patent to W.R. Grace and Company for $400 (roughly $,000 in dollars). Using that money, Hunt then paid the $15 owed to a friend and kept the remaining amount of $385 for himself. In the years to follow, W.R. Grace and Company would make millions of dollars in profits from his invention. Locking safety pin The sharpened pin, that is attached to a coiled wire is connected with a cap that is hooked at the end of the wire. Pushing the pin into the opening of the cap secures the safety of the pin, and the clasp is then closed. Medical aspects The laryngologist Dr. Chevalier Jackson devised special instruments for removing swallowed safety pins. Because small children often swallowed them and open pins could be lodged dangerously in their throats, Jackson called them "danger pins" and sometimes displayed arrangements of those he had extracted. Safety pin ingestion is still a common problem in some countries today. Culture During the emergence of punk rock in the late 1970s, safety pins became associated with the genre, its followers and fashion. Some claim the look was taken originally from Richard Hell whom the British punks saw in pictures, and whose style they adopted. This is disputed by a number of artists from the first wave of British punks, most notably Johnny Rotten, who insists that safety pins were originally incorporated for more practical reasons, for example, to remedy "the arse of your pants falling out." British punk fans, after seeing the clothing worn by such punk forerunners, then incorporated safety pins into their own wardrobe as clothing decoration or as piercings. Thus shifting the purpose of the pins from practicality to fashion. The safety pin subsequently has become an image associated with punk rock by media and popular culture outlets. Safety pins worn visibly on clothing became a symbol of solidarity with victims of racist and xenophobic speech and violence after the Brexit referendum in the United Kingdom in 2016. Later that year the symbol spread to the United States after Donald Trump's election to the presidency.
