Knapping enjoyed a resurgence after the invention of the flintlock, which required a well-shaped and properly sharp piece of flint in order to ignite the priming powder. It once again became obsolete after the popularization of the percussion cap in the second half of the 19th century.
Knapping has once again become useful, for creating extremely sharp surgical blades. The global demand for these is very small, however.
Knapping is still used in the UK when building traditional-style walls, prevalent in some areas of the country. Usually this involves creating a straight surface on a round or otherwise irregular piece of flint.
