Flint and steel is a traditional method used to start a fire. It involves striking a piece of steel against a hard rock called flint. When the two materials collide, tiny sparks are produced. These sparks can ignite dry materials like tinder, which is essential for building a fire. This technique has been used for centuries, dating back to ancient times. It was crucial for survival, providing warmth, cooking, and protection. Today, flint and steel are often used by campers and survivalists who appreciate the skill and reliability of this old-fashioned fire-starting method.
