What is a common disadvantage of owning a Flintlock firearm?

A common disadvantage of owning a Flintlock firearm is that the flint can wear out or break. Flintlock firearms utilize a mechanism that strikes flint against steel to create a spark, igniting the gunpowder in the firing pan. Over time, the flint can become dull, chip, or fully break, necessitating its replacement to ensure reliable firing. This can be a more frequent maintenance task compared to more modern ignition systems, which may not require such periodic replacement of consumable components. Additionally, the need to routinely check and replace the flint adds a layer of upkeep that can be seen as an inconvenience for the owner.
