Keep Improving Old Inventions

What can you improve or “re-invent” for an updated world?

People have been using locks for more than 4000 years. The oldest key-operated locks were found in ancient Egypt. Throughout the ages, locksmiths had to always be inventing new locks to outwit thieves who had figured out their old locks.

In 1861, an American inventor named Linus Yale, Jr. patented a pin-tumbler cylinder lock. The design combined features of several locks – including the Egyptian design. Because the new idea built upon of centuries of ingenuity, Yale’s lock outsmarted almost all thieves, and continues to do so today.
