International Safety Pin Day – April 10, 2025

We mark International Safety Pin Day on April 10 every year. This unofficial observance is dedicated to the simple but clever and useful invention — safety pins. The safety pin is used for a lot of things. For example, it is used to secure clothes together, as a decoration, and is also worn as accessories. Walter Hunt invented and patented the safety pin, and the truth is that the design of this object has not changed much since its invention. It is a day to celebrate the simple, useful invention of Hunt.

History of International Safety Pin Day

In April 1849, Walter Hunt, born in 1796, invented the safety pin to pay a debt of $15 to a friend. Walter Hunt was an American mechanic. Hunt did not get any real cash or fame from his invention so he sold the patent to “W. R. Grace and Company” for $400. He paid his friend back with that money and pocketed the remaining $385. Hunt made the safety pin to improve the ‘dress pin’ and prevent injuries to fingers and other parts of the body. It said that he made the safety pin with a brass wire of about 8 inches in length.

The basic design invented by Walter Hunt in 1849 is still used today. Although the safety pin was invented to fasten fabric and clothing, it is also used as an accessory, as jewelry, and in place of rings for body piercings. Safety pins have hundreds, if not thousands of uses. Some of them are pinning together two pieces of clothing to sew, pinning together cloth diapers, keeping cloth bags closed, decorating clothing, etc.

Walter Hunt came up with numerous inventions. He also invented a repeating rifle, a fountain pen, and a knife sharpener. He also invented the sewing machine, which was his most noteworthy invention besides the safety pin. The truth is that he didn’t patent this invention because he thought it would take away jobs from those who sewed by hand. Hunt often did not reap the full economic benefit from their inventions. In 2015, this holiday was originally called Safety Pin Day, and in 2017, it was often referred to as International Safety Pin Day. Shortly after, it was sometimes called National Safety Pin Day,
