Using flint chips.
It is possible to greatly facilitate the production of fire with the help of a flint, if you scrape off a little shavings from it on the material to be ignited. The chip scraping process is illustrated in this video..
Winter gas bottle insulation.
When you turn on the gas burner in winter, the gas inside the container in a liquid state evaporates and enters the burner itself. During the evaporation process, the gas remaining in the cylinder is intensively cooled. As a result, the power of the burner drops significantly, and the gas flow increases. Moreover, the smaller the cylinder, the more it is prone to hypothermia. Subcooling of a gas cylinder in conditions of low ambient temperatures is especially relevant. To heat a gas cylinder, it is necessary to use a heat shield, and it is desirable to insulate the cylinder itself. For example, making a cover on it and using foam insulation cut between the cover and the bottle itself, cut with the necessary piece from an old tourist rug (karemat).
sometimes very tedious with a saw.
We recommend trying a regular garden pruner for these purposes. The time for cutting and cutting by secateurs of four or five long 1.5-2 cm branches or forest shoots will take no more than 3-4 minutes, and their small and thin branches are perfect for kindling the fire itself. The use of a garden pruner instead of a folding saw becomes even more relevant if you use a folding compact stove or some modification of it for cooking.
Then the benefits are even more obvious. Such stoves are unpretentious and burn any firewood, but it is better that they are thicker and its size. The photo shows the amount of firewood on which in such a compact stove confidently boils and boils for about 15 minutes, 1.5-2 liters of water.
