What is flinty?

Flinty refers to a hard and firm texture, often related to rocks or stones. Flinty rocks are known for their ability to generate sparks when struck against metal or another piece of flint. The term can also be used to describe a person who is tough, resilient, and unyielding in their personality or behavior. A flinty personality may be characterized by a strong will, determination, and a no-nonsense attitude. The word "flinty" is derived from the mineral flint, a variety of quartz that is commonly used for making tools and weapons.
