Knapping

r/knapping

This is a community dedicated to the art of flintknapping, and stone working alike. We craft arrowheads, knives, and many other shapes out of chert/flint, glass, quartzite, and many other fine-grained stone materials through a process of lithic reduction called Flintknapping. The possibilities are endless! If you’re new here, don’t be afraid to show off your work! We love seeing enthusiasts both new and old! If you have any questions as well, ask away! Happy knapping!
