Corkscrew
The basic design of a corkscrew is been based on a tool called a gun worm. This was used by a musketeer to remove an unfired bullet from a musket's barrel. In the 1800s, many manufacturers that made gun worms also made corkscrews. The first patented corkscrew in England was by Samuel Henshall in 1795. In 1883 a flat, lever-style corkscrew called the waiter's friend was invented in Germany by Karl Wienke. It is commonly used in restaurants today.
