What is the size of the flint?

The size of flint can vary widely depending on its formation and use. Natural flint nodules can range from small pebbles to larger chunks, typically measuring several centimeters in diameter. For specific applications, such as tool-making or in modern uses like flint in lighters, flint is often shaped and can be much smaller, sometimes just a few millimeters across. Overall, the size is quite variable based on context.
