Flint

Flint is a Material Object that can be used to set any flammable objects on fire by rubbing it. It has the unique ability to set parts alight that it strikes, provided they are flammable. This is useful for early game lighting and heat.

To rub flammable objects using flint, drop a flint that is closer to an object. Once done, flammable objects will emit flame. Water is used to eliminate flames from any flammable objects.
