How did the vikings start fire?

Vikings typically started fires using a combination of flint and steel, creating sparks that ignited tinder made from dry materials like moss, grass, or wood shavings. They often carried a fire starter, known as a "fire steel," and would strike it against flint to produce sparks. Additionally, they might have used more primitive methods like rubbing sticks together or striking stones to create friction and heat. Once a small flame was established, they would gradually add larger pieces of wood to build a stable fire.
