Starting a fire by rubbing a dry stick and stone together is highly unlikely and not an effective method for fire starting. The technique you are referring to, known as friction fire starting, typically involves rubbing two sticks or two rocks together to generate enough heat to ignite a combustible material like dry tinder.
Rubbing two sticks together, such as using a bow drill or hand drill method, relies on the friction between the two sticks to create heat. The heat generated by the friction can eventually raise the temperature of the surrounding materials, including the tinder, to the point of ignition.
Using a stone instead of a stick significantly reduces the effectiveness of this method because stones are not as efficient in generating frictional heat. The surfaces of stones are generally smoother and harder compared to sticks, making it more challenging to create the necessary heat to start a fire. Additionally, stones are less likely to produce the fine dust or ember that is crucial for igniting the tinder.
It's important to note that fire starting through friction is a skill that requires specific techniques, materials, and practice to be successful. There are other reliable and safer methods for starting a fire, such as using matches, lighters, fire starters, or other fire-making tools specifically designed for that purpose.
