3D model of flintlock mechanism

"The basic goal of the flintlock is simple: to create a spark that can light the gunpowder stored in the barrel of the gun. To create this spark, the flintlock uses the "flint and steel" approach. The idea behind flint and steel is straightforward. Flint is an amazingly hard form of rock. If you strike iron or steel with flint, the flint flakes off tiny particles of iron. The force of the blow and the friction it creates actually ignites the iron, and it burns rapidly to form Fe3O4. The sparks that you see are the hot specks of iron burning! If these sparks come near gunpowder, they will ignite it." (quote from HowStuffWorks site)

The flintlock mechanism (wikipedia article) was a firing mechanism used on muskets and rifles in the 17th, 18th, and 19th centuries. It is commonly referred to as a "flintlock" (without the word mechanism), though that term is also commonly used for the weapons themselves as a whole, and not just the lock mechanism.

The flintlock was developed in France in the early 17th century. Though its exact origins are not known, credit for the development of the flintlock is usually given to Marin le Bourgeoys, an artist, gunsmith, luthier (maker of stringed musical instruments) and inventor from Normandy, France. Marin le Bourgeoys's basic design became the standard for flintlocks and quickly replaced older firing mechanisms throughout Europe. Flintlock weapons based on this design were used for over two centuries, until they were finally replaced by percussion locks in the 1840s and 1850s.
