Can you provide information on identifying flint and its uses in prehistoric tools"?

Flint is a type of sedimentary rock that is often gray or black in color and has a glassy appearance. It is commonly used in prehistoric tools due to its ability to be easily shaped and sharpened. Flint tools were used for cutting, scraping, and hunting by early humans. Identifying flint can be done by looking for its characteristic conchoidal fractures, which create sharp edges when broken.
