The Master Lock is an undying invention. Made out of laminated steel, the locks can take a beating and still stay secure, ensuring their place in the pantheon of “good ideas.” Invented by Harry Soref in 1924, the company used pieces of scrap steel stacked on top of each other to create a lock that could survive a gunshot.
Wired has an in-depth look at Soref’s life. Remember to thank Soref every time you lock someone in your garage.
