For mowing grass in the country or in the villages and now widely used hand braid. However, many do not know how to keep it in working order. But it is the most finely tuned tool from agricultural implements. And the main question when dealing with a scythe - is how to maintain the sharpness of her blade for fruitful work. Today's theme is devoted to how they beat the scythe for high-quality sharpening. However, first of all we will consider what kind of braids there are in principle, and for which each of them is applied.
Three types of braids
The most common of the whole braid family is Lithuanian. Its name came from a long time when they were cast from steel, and then only forged. Litovki were made on a par with swords, so steel in them was of the same quality. Now they are made by the method of stamping out of tool steels, so the scythe-litka well holds the cutting edge and is remarkably sharpened. There are several sizes for easy mowing of grass in different conditions. It is better for
Spit-salmon is used in places where there are many bumps and irregularities. Its shape resembles a large sickle. It can also be easily recognized by the curved handle.
The serpent, whose blade is short enough compared to the rest, is used for dry grasses.
Of all the varieties of braids, Lithuania was the most popular. There are several sizes: № 5, 6, 7, 8, 9 and 10. All of them are measured in decimeters, and the length of the blade varies from half a meter to a meter. The choice of such a braid size is of great importance. The smaller the length of the blade, the easier it is to mow areas with an uneven surface and in forests, between trees. The more hollow and open the terrain, the longer the blade. On the example of the Lithuanian, we will study in detail how to beat the braid, and what tools we will need for this.
Also, the length of the braid was traditionally chosen based on the individual characteristics of a person: growth, constitution and physical strength. After all, the bigger the braid, the heavier it is, and given that it gets a strong resistance to the grass, you need to have good physical data.
To make it easy to harvest grass, the spit tool must be very sharp. Before sharpening it must be repulsed. This is done so that the cutting edge becomes denser, thinner, and remains sharp for longer. To ensure that the spit is really a useful tool, which is convenient to work with, it must be repulsed before sharpening. If this is not done, but simply sharpened, such an inventory will, at best, last for ten minutes of work, and then it will be necessary to sharpen it again. Therefore, now we will study in detail how to properly repel the braid, so that it cuts well, and even for a long time did not get stupid.

Preparing the tool
To qualitatively repel the braid, you need to have a smooth head without dents from repeated use. Usually they sew on machines. And, of course, you need a smooth hammer, which should also not have a hilly surface or bevels from the blows. A qualitative tool is convenient to use, because everything is visible, and the results of strokes are predictable. If the hammer or the granny is uneven, undesirable dents may appear during the impacts, which, if not removed, can damage the blade.
What is a grandmother
A grandmother is a small piece of metal on which the braid is hand-beaten. On one side is the butt, and on the other end - the point, in order to be able to drive it into a suitable piece of wood for reliable fixation. Thanks to this simple tool and create a working edge for cutting tools.
Where to get or how to make a grandmother
These simple devices are sold in specialized stores. Of course, it's easier to find them on the net than in the city to find a department for mowers. If you can not find the grandmother, you can make it yourself. After all, by and large, it's just a piece of steel. Ideal for large files, springs, the old hammer can also be fixed and used. It is very important to choose a material from hard steel. Because if it is very soft, then the hardened scythe will blot it out when it strikes. And the resulting irregularities can significantly damage the cutting edge.
Begin the process of beating the braid
So, the grandmother is driven into the deck, and the blade itself is removed from the handle. So it will be more convenient to work. If you do not want to shoot, then you need to provide a support for the handle, with which the braid is placed in a convenient position for punching.
The blade before work is immersed for half an hour in water, where it becomes darker. This is necessary in order to see the edge, which is formed after the execution of strikes. It will be much lighter than the rest of the surface.
The plait is placed on the head with a cutting edge to itself, after which it starts to strike from the heel, without applying special force and as if pulling the steel in its direction. The hammer must be brought in when striking from the side of the braid, and finish the movement, as if pulling it to him. Thus, the metal begins to slowly pull in the necessary direction. Do not rush and speed up the process with stronger punches. This can lead to an uneven edge, along which waves can go, or the blade is generally deformed. In this case, the braid will be spoiled. It is worth doing everything slowly, therefore, how to repel a braid with a hammer is a rather laborious process that requires gradual and patient advancement.
To forge the cutting edge smoothly, it is necessary to shift with each stroke, from the heel moving evenly towards the end of the blade. After the first flattening, the whole edge should remain flat, without undulating bends. If you see somewhere that there are dark places, then this place was not forged properly. Very carefully, even weaker blows than usual, you need to fix everything, so that the surface becomes uniform. Then they beat the other side in the same way. After that, they look: if the edge is not enough rasklepana, begin again to do the same movements, from the heel to the end of the blade, until they achieve the desired effect. And thus, in turn, riveting one or the other side, the blade is brought to the desired thickness. Over time, when more experience is available, the question of how to repel the braid will not be so acute. Everything will be done for fewer approaches and time.
Finishing the riveted surface
When finished, when the desired thickness is almost reached, it is worthwhile to apply even weaker blows, because they will allow a little to smooth the dents left from the previous rivets. Well, those that remain will be removed during grinding with an emery bar. A well-cut braid has a smooth cutting edge, the ends of which, if you look closely, have slightly torn edges. They, with the subsequent sharpening, give the instrument such a sharp blade.
Sharpening the braid
Sharpen the braid in two stages. The first is scraping, the second is editing. Scraping is necessary in order to make the surface smooth and remove excess metal. To do this, use a scraper. It is made from a trihedral file, from which a rough surface is grinded on the machine, thus making its faces sharp. The scythe-litka is sharpened only on one side - with the one that is at work from above. For scraping, you need to hold the scythe around the heel and hold the scraper along the edge along the edge. You need to do this several times, creating a constant angle of sharpening. When burrs begin to appear on some parts of the cutting edge, it means that the scraping is finished and it's time to start editing. To do this, use a sanding block. They spend the same way as the scraper, trying to maintain the same angle of sharpening. It is very important that the angle be the same as for scraping, because, by slightly changing it, you can, on the contrary, blunt the scythe.
Choice of braid
We have completely learned how to beat a braid, and then sharpen, now it is worth telling how they choose this tool. Now, when there are many varieties of braids and their producers, very often there is a substandard product. Especially braids - even in the Soviet era, when everything was just GOSTs, it was difficult to find quality ones. Usually of three was one good, and the rest of the inappropriate for this steel. Now it does not matter how much a braid costs, even among very expensive models often come across bad. In general, it's better to check this thin tool yourself before buying.
What to look for when choosing
In the store when choosing a scythe it is always worth paying attention to the manufacturer's brand. Good companies that produce high-quality goods always squeeze their logo on the metal of the product. This significantly helps to save the real products from fakes. The stigma is mainly put in the area of the heel of the spit, so it is worth first of all to inspect this place.
The folk methods of checking the quality of the braid
The first way: you need to take a piece of window glass and hold them on the edge. If the glass goes bad, there is a feeling that it is clinging to something, so you should not take such a scythe. Her steel is soft, and with her will be more trouble than doing. There are even such specimens that when you conduct this experiment, metal chips are removed from their surface. Naturally, with such an instrument, the question of how to properly repel a scythe will not even arise because it is worthless. Ideally, the glass should pass smoothly along the blade, leaving no trace on it. The second way: you need to put a match on the edge of the scythe blade across, balancing it, and gently push it on one side. If the match turns, then this is a quality braid.
There are also more stringent methods of verification. It is necessary to take a metal nail and pass it across the blade. If it stays without visible defects, or even better, chips are removed from the nail, this is a 100% quality tool that will last for decades. Of course, longevity also depends on how the spit is repelled when it is used.
You can hit a braid with a braid on a tree. If the sound is high and long, the braid is good. You can also end it in a board on the floor and press on top. If the steel evenly bends, and when released returns to its previous position, this braid is worth buying.
Prices for braids
In shops and on the Internet the cost of braids is different. It varies from 300 rubles to 1500( sometimes higher, this is the average).Naturally, at a low price a good tool to buy is unrealistic, since the braid is hand-held, despite its simple appearance, is a rather delicate tool that is very difficult to create without special technology.
