The horn has a specific structure which is different from the round edge that we see on our fingers. It splinters and cracks into flakes, so it is more similar to a flint than a chalk. The outside of the cone dries out and flakes and is scratched off by the cat, while the inside of the cone is the newer horn that grows towards the apex as a new blade edge. ...
