What is the difference between flint and fire?(1)

Flint seems to be a kind of iron alloy of cerium, which is relatively brittle. Under the high temperature of the friction of the iron wheel, the grinding dust and O2 will burn. The temperature of the spark can ignite gasoline, butane gas, etc. At present, there is quartz pressure. The electrostatic spark generated by the electric ignition device has high energy but small spark, and the ignition efficiency is high.
Fire sickle is an early fire tool. It can be used with flint and velvet to make fire manually. It is named because the iron rod used to make fire from stone is shaped like a sickle. Since the invention of ironmaking and thousands of years before the invention of the match, it has been the main fire tool of mankind, and it is also the decoration that almost all men must wear on their waists, indicating their identity and status.
Starting from the Iron Age, people invented a fire tool that could be used to make fire at any time. This is the fire sickle. The fire sickle, also known as the fire knife, is mainly a slightly curved and smooth mouth that was originally about 5 cm to 8 cm. A purse made of leather and other materials is generally fixed on the iron bar, and flint and tinder are usually stored in the purse. Flint is also called flint. It is a hard stone or block of stone. It is irregular in shape and sparks when it collides with steel. Tinder is made of flammable materials such as lint or sulphur. It can be ignited when it touches sparks. There is usually a metal ring on the purse of the scythe, which can be worn with you and is convenient to use.
The usage of the fire sickle is to first open the cover of the fire sickle purse, take out the flint and tinder. Ordinary people use their left hand to hold the flint and press the fire paper between the flint and their fingers, and the right hand holds the purse of the fire sickle, and aim the sickle at the flint and slam the sparks to ignite the fire velvet. This process of hitting the stone generally needs to be repeated several times until the tinder is ignited. The smoking tinder can be used to light the cigarette directly by blowing air, or it can be used to ignite the fire paper or the fire rope.
