GENERAL KNOWLEDGE

Detailed explanation-1: -Mechanic and independent inventor Walter Hunt secured a place in American history when he invented the useful, everyday device known as the safety pin in 1849. Born on July 29, 1796, Hunt lived and worked in New York, where he invented a variety of tools and household items and made improvements to existing machinery.

Detailed explanation-2: -For emergency clothing malfunctions, this handy invention is still unsurpassed. In 1849 US mechanic Walter Hunt filed a patent for ‘a pin made of one piece of wire or metal combining a spring, and clasp or catch’. If there’s isn’t a board game where everyday objects are described and then guessed there should be.

Detailed explanation-3: -Hunt made the invention in order to pay off a $15 debt to a friend. He used a piece of brass wire that was about 8 inches (200 mm) long and made a coil in the center of the wire so it would open up when released. The clasp at one end was devised in order to shield the sharp edge from the user.
