Flint, this is a device for the production of sparks, which in turn ignite any combustible material, tinder, help to make fire. Ogniva was actively and widely used in everyday life before the appearance of matches, at the present time, due to the complexity of the process itself, it is practically not used to produce fire.
Types of flint, the role of flint in the survival kit, features of the use of flint during survival in emergency conditions.
The modern flint is usually a rod of circular cross section made of ferrocerium (mishmetal), an alloy containing iron, silicon and rare earth elements: cerium, lanthanum, neodymium, praseodymium and others. For convenience, industrially produced flints can be equipped with handles of various configurations and a steel strip included in the kit, usually having a notch on the sides. The advantages of flint over fires such as matches and a lighter are obvious.
It is not afraid of moisture, works in the wet state and in the wind, does not freeze, not brittle, unpretentious. It does not require maintenance and refueling, does not deteriorate over time, depending on the size, it has a resource from hundreds to several thousand applications. The temperature of the resulting sparks is about 3000 degrees. The main disadvantage of a flint is that, unlike matches or a lighter, it does not produce fire immediately, but at first it only produces sparks. Which still need to be managed to set fire to a dry and flammable suture, which is not always simple and quick to do under certain conditions, for example, in rain or snow.
Types of Flint.
The flint which is currently being manufactured industrially can be relatively arbitrarily divided into two main types, manual and semi-automatic. To work with the former, you need to use both hands; The price of a flint of both types ranges from one to several tens of dollars and depends primarily on the bells and whistles with which they are equipped. As well as the marketing policy of the company that issues them.
At least two duplicate means for producing fire must be provided. For example, the main matches or a lighter, and a flint of any kind as a spare. It is very simple and quick to light a fire with one movement of the hand striking a match or using a lighter, but this is only when they are in working condition.
But a lighter, like any mechanical device, can break, and the more components it contains, the higher the probability of failure. Matches can simply end or get wet and lose their properties. But what about the flint? What’s flint? It is reliable, it only needs to be learned to apply it correctly. More practice and in any situation without fire you will not stay.
Some tips for using flint in the field.
1. For cutting sparks from flint, any steel can be used as a chair. However, it is preferable alloyed, which is not corrosion resistant, it gives sparks more than any stainless steel.
2. If you have a choice, then do not use the cutting edge of your knife as a chair. You run the risk of blunting it at best and burning it out at worst, because the temperature of the sparks reaches 3,000 degrees Celsius. Both that, and another, it is not at all easy to correct, if at all possible in the arisen situation.
3. If there is no regular chair in the kit with the flint, then in its role it is more reasonable and practical to use a small piece of a hacksaw blade. Or, in advance, make a special platform for working with the flint on the knife butt closer to the handle.
