Which type of ignition system uses a spark from flint?

The flintlock ignition system is historically significant as it utilizes a small piece of flint to generate a spark required for ignition. In a flintlock mechanism, the flint is held in a jaw and strikes against a steel frizzen when the trigger is pulled. This striking action creates a shower of sparks, which then ignites the priming powder located in a flash pan. This powder subsequently ignites the main charge in the barrel, allowing the firearm to discharge.

The design of the flintlock was a major advancement over earlier systems, particularly in terms of reliability and weather resistance. It became popular in the 17th to early 19th centuries and was one of the primary means of ignition before more modern systems, such as percussion caps, took over. Understanding how the flintlock operates provides insight into the evolution of firearm technology and the importance of ignition systems in muzzleloading firearms.
