Quick Answer
Natural flint can be found in areas with exposed limestone or shale, often near water sources such as rivers or streams, and at beaches where the constant erosion has uncovered flint deposits. Flint can also be found in areas with a history of ancient human habitation. Look for flint in areas with a high concentration of sharp-edged rocks.
Where to Look for Flint
When searching for flint, focus on areas with exposed bedrock, such as riverbanks, creeks, and coastal areas. Look for rocks with a high concentration of silica, which will be harder and more brittle than other rocks. Check for areas with a history of erosion, such as gullies or ravines, where flint may be exposed.
Identifying Flint
To identify flint, look for rocks with a glassy appearance and a conchoidal fracture pattern. Flint will often have a smooth, rounded edge, and may exhibit a “flake” when struck. Hold the rock up to a light source to check for a glassy appearance. Compare the rock to a known piece of flint to confirm the identification.
Collecting and Preparing Flint
Once you have identified a piece of flint, remove it from the surrounding rock by gently prying it loose with a knife or a screwdriver. Clean the flint by scrubbing it with sand or dirt to remove any debris. To prepare the flint for use with a firesteel, find a sharp edge on the flint and use it to shave off small flakes, gradually creating a sharp, V-shaped notch.
