Happy Birthday YKK
Happy birthday to the hookless fastener!
One hundred and two years ago this week, a patent was given for the forerunner of the zipper. In the start the “zipper” was used mostly in rubber boots, and it was BF Goodrich that gave it the name “zipper.”
Something you may not know is that 80 percent of all zippers say YKK on them. That’s because they don’t make them in America any more. They all come from the Yoshida Kogyo Kabushikikaisha company in Japan (much too long to put on the zipper, so YKK). Look at yours. It’s there.
So happy birthday to the “clasp locker” that holds our pants up and zips our backpack shut.
