Flints
Flint is a hard, sedimentary rock primarily made of silica. Known for its ability to be knapped, or shaped by striking, it has been used for thousands of years to create sharp tools and weapons, particularly by ancient cultures. When struck against steel, flint can create sparks, making it useful for starting fires. Its durability and sharp edges have made it a crucial resource for early humans in crafting tools and building shelters, showcasing its importance in technological advancement throughout history. Today, flint is often found in gravel deposits and is also used in modern construction and manufacturing.
