Wood and metal processing
Scissors are used for both manual and machine cutting of metals. The angle of sharpening p at scissors ranges from 65 to 85 ° depending on the hardness of the metal being cut: for soft metals (copper, etc.) it is 65 °, for metals of medium hardness 70-75 °, for hard metals 80-85 °. To reduce the friction of the scissors knives when working on the blades, a clearance angle a equal to 1.5-3 ° is created. Scissors knives are made of U7 carbon steel; their cutting part is hardened.
Cutting with hand scissors. Manual metal shears are shown in fig. 1. The most common sizes of scissors are 250-320 mm (along the total length of the scissors).
The hand scissors are divided into right and left. On the right shears, the bevel on the cutting part of each half is on the right side, and on the left, on the left side. When cutting the sheet with the right scissors, the risk on the cut metal is always visible. When working with left scissors, in order to see the risk, you have to bend the cut metal with your left hand, shifting it over your right hand, which is very inconvenient. Therefore, cutting the sheet metal in a straight line and in a curve (circle and rounding) without sharp turns is carried out with the right scissors.
Manual scissors can cut sheet steel up to 0.7 mm thick, roofing iron up to 1 mm thick, copper and brass sheets up to 1.5 mm thick.
When cutting metal, the scissors do not open completely, but only enough so that they can grab the sheet. When fully opened, the scissors do not cut, but eject the sheet. When cutting round discs with scissors, the discs are turned counterclockwise, while the scissors should not cover the cut line of the cut.
Cutting with chair scissors. One of the halves of these scissors has a handle with a pointed end bent downward; with this end, the scissors are fixed in a wooden bar. The second half. with a straight handle. serves for hand operation.
The chair scissors are stable when cutting and give a lot of freedom to the hands of the worker. They cut sheets with a thickness of 2-3 mm.
Cutting with lever scissors. In fig. 3 shows lever hand-held shears, designed for cutting sheet metal, thin bars and shaped material, and lever hand-held shears, used for straight cuts of sheet metal up to 2 mm thick (for steel) into strips. One knife is installed on the table of the swing scissors, on the lever itself, the second. A balance weight is placed at the end of the arm.
The sheet metal is cut by one person using the fly shears. The sheet is laid on the table so that the cutting line (when cutting with markings) coincides with the blade of the lower knife. Pressing the sheet with the upper bar, the lever with the upper knife is lowered with a strong movement. Then the lever is “squeezed” until the required part of the sheet is cut.
When cutting without marking, the width of the strips is adjusted with a movable guide ruler.
Cutting with parallel scissors. These shears, sometimes called guillotine shears, are used to cut sheet metal (for steel) up to 4 mm thick or more. In parallel guides of the scissors, a slider with an upper knife obliquely attached to it walks up and down; the lower knife is fixed motionlessly in the bed. Raising and lowering the top-
its knives are carried out by a crank mechanism, which receives movement from the working shaft, which is driven into rotation by an electric motor through a transmission from a drive pulley.
Cutting with circular (round) scissors. In fig. 5 shows circular (circular) shears used for cutting sheet metal with an unlimited cutting length, as well as for curved cutting. The cutting tool is disc knives, located one above the other and rotating in different directions when working. To cut straight strips, the knives-discs are placed in parallel; for cutting curved shapes (circles, holes), knives and their axes are positioned at an angle to each other. You do not need to feed the sheet into disks; rotating discs themselves tighten the sheet,
Types of pipe scissors
Increasingly, the distribution of cold and hot water pipes, even heating, is made with plastic, polypropylene, metal-plastic pipes. They are easier to install, but a smooth cut is required for a high-quality connection. And they cut pipes with special scissors or a cutter. There are different types, so first you need to find out about them.
For the installation of plastic or polypropylene water pipes or heating systems, pipe scissors are required
Actually, the design is not that important. It is important how smooth the cut can be made by the pipe scissors, what diameters they cut, with what materials and types of reinforcement they work. But let’s start with the types and types of structures.
With electric drive
Electric and cordless pipe cutters are already a tool for professional use. Good because it does not require physical effort. All you need to do is press the button and hold the pipe straight while the device is working. Electric shears are usually equipped with a button to return the knife to its original position. Electric pipe shears can be:
- Mains powered.
There is a tool for cutting pipes with an electric drive. from the mains and the battery
By design, they are most similar to the model of the “pistol” type. They look more massive due to the plastic protective case. And the motor and batteries (if any) also need to be hidden somewhere. But since almost no effort is required during work, the weight is not critical (from 1 to 2 kg).
There are no complications at this point. You need to track two positions:
- the maximum diameter of pipes that the scissors can cut;
- which pipes they can cut.
Take a close look at these characteristics. It can be a shame: you buy scissors for polypropylene pipes for a couple of thousand, and then it turns out that they do not cut polypropylene.
First of all, we look to see if the type of material we need cuts, then we pay attention to the diameters
Another piece of advice. Better to get a cutter that can cut the pipe to a size larger than you plan to mount. For example, you will cut a pipe of 32 mm as much as possible, but take a tool for 40 mm. Why? The pipe of the maximum size is very difficult. Namely, they usually do the main wiring. A smaller diameter is used only for layering. And the tool for a larger diameter is slightly larger in size (and slightly more expensive), but cuts easier.
By the way, for a cheap tool, the pipe of the declared largest diameter sometimes simply does not fit into the holder. So you have to check. If there is no piece with you, compare the dimensions of the cutting part with similar ones. Are the sizes more or less the same? Fine. If the ones you choose look smaller, it is better to postpone.
How to choose a pipe cutter
For home use or for occasional use, a mechanical pipe shear is usually taken. At the same time, the design is chosen so that it is “cheap and reliable”. The most commonly purchased ratchet scissors. In principle, a justified choice. Beginning professionals also work with them. You just need to choose the right model.
Important structural components of a pipe shear
In general, you can give the following recommendations for choosing the type of pipe cutters. A thin-walled pipe without reinforcement of any material is cut with a pipe cutter or scissors of normal quality, regardless of the design. Diameter restrictions. 32 mm, wall thickness. up to 4-5 mm. Any pipes, which ones? Yes, everything: metal-plastic (MP), polyethylene (PERT, PEX), polyvinyl chloride (PVC), PVDF, low-pressure polyethylene (HDPE), polypropylene (PP, PPR or PPR), including fiberglass-reinforced and even small pipes (diameter 16.20 mm), reinforced with aluminum foil. For the same pipes, but with a diameter of 4 mm and more, more powerful scissors are needed. They must be larger and “tougher” in assembly.
Which scissors are best for PVC, PPR, PET, MP pipes
For reinforced polypropylene and PEX with a diameter of 25-40 mm, a good roller cutter is required, and for even larger ones, you already need a guillotine or the same roller shears, but from a professional series.
Shears for cutting pipes: polypropylene (PPR), plastic, metal-plastic
Plastic plumbing and heating. this is no longer surprising to anyone. But the pipes must be cut. With what? There is a tool for this, usually called pipe shears. And also. with a cutter, pipe cutter. There are several designs that look different, although they serve the same function. And up to ten thousand or more.
What a blade could be
The main working part of the pipe cutter is the blade. It can be made of tool (cheaper and softer type of steel) and alloy (more expensive and durable) steel. Generally, the alloy steel blade can cut plastic and copper pipes. PP pipe scissors have a tool steel blade.
Steel type is not everything. You have to look at the thickness of the blade. If it is thin, with a large diameter, the cut goes to the side and cuts the pipe at an angle. But we need something at 90 °.
Pistol pipe cutter mechanism
Why make a cut strictly at right angles? To make the connection strong and durable. This is important for pipes of any type, but it is critical for metal-plastic and for polypropylene, reinforced with foil.
The thicker the blade, the easier it is to work. By the way, there are models of scissors for polypropylene pipes with a removable blade, there are those in which the blade and the “ladder” of the ratchet mechanism are one whole. The second option is more durable. The fewer connections, the longer the service life.
Mechanical, with manual “drive”
There are options for home and professional use. But even if you only need for repair or for yourself, it is better not to take absolutely cheap ones. Smooth cut even on a thin pipe will not work.
- Pipe scissors. They are very similar in shape to ordinary ones. Naturally, the body is more durable, the blades are made of stronger steel, not even, but with rounded curves. to make it easier to lay the pipe. Large diameters, and dense materials (polypropylene) are cut with great difficulty, even if the description states a diameter of 40 mm. For small-diameter pipes, they are suitable, for large ones, either a larger one or another type is needed. May be:
- With a return spring (pictured below left). You will have to cut off solely due to the strength of the hands. Of the auxiliary mechanisms, only the return spring, which returns the flattened blades to the open position. If you want to pump up, this model is for you. Even thin-walled polyethylene is very difficult to cut. Is that for flexible floor heating pipes will go.
These are exactly the models that are called “pipe scissors”
What else can you cut non-steel pipes: roller pipe cutter and guillotine
Which design is better to choose? If you are only for home use, it makes sense to buy the first type. They are easy to work, although they require effort, but to assemble a plastic water supply system or a polypropylene system, not much will have to be cut. You can also consider roller pipe cutters. Also an inexpensive and oversized tool. The guillotine is generally not needed for private traders, and the pistol is not so relevant due to the high price.
How iron deficiency manifests itself in the body
Distinguish between latent iron deficiency and iron deficiency anemia itself. The appearance of anemia may be indicated by the following symptoms: signs of general weakness, decreased appetite, brittle hair and nails, a change in taste (desire to eat chalk, toothpaste, ice, raw meat), pallor of the skin, shortness of breath, heart palpitations.
A blood test will determine a decrease in the level of hemoglobin, erythrocytes, color index, serum iron.
Please note that only a doctor can correctly and accurately diagnose, taking into account the degree of anemia, concomitant diseases and test results! The doctor also determines which drug is best to take, and also gives recommendations regarding the dose and duration of the course of treatment.
Why iron deficiency occurs in the body
The following factors can be the cause of iron deficiency:
- bleeding. Prolonged and often recurring uterine, pulmonary, gastrointestinal and nosebleeds, heavy menstruation;
- conditions accompanied by an increased need for this element: pregnancy, lactation, chronic diseases, a period of intensive growth in children and adolescents;
- impaired absorption of iron caused by intestinal inflammation, taking drugs. antagonists;
- vegetarian diets, artificial feeding of children of the first year of life, unbalanced nutrition in older children.
How iron supplements work for anemia
For the treatment of low levels of iron (Fe) in clinical practice, preparations of bivalent and ferric iron are used. Preparations with the active substance in the form of ferrous iron (Fe 2) have better bioavailability, which allows the active substance to be almost completely absorbed in the body. Given these properties, ferrous iron medications are available in oral dosage forms. In addition, their price is lower than the cost of medicines based on ferric iron (Fe 3).
Fe 3 is converted to Fe 2 in the presence of an oxidizing agent, the role of which is most often played by ascorbic acid.
In the small intestine, Fe binds to a special protein. transferrin, which transports the molecule to the blood-forming tissues (bone marrow and liver cells) and to the places of Fe accumulation in the liver.
The process of absorption of Fe and a decrease in its bioavailability in the body can be influenced by some products and preparations, in particular, tea, milk, tetracycline, chloramphenicol, drugs for heartburn from the antacid group (Maalox, Almagel), calcium-containing drugs. Better absorption of Fe is promoted by meat, fish and lactic acid.
Please note that the body’s ability to excrete excess iron is very limited, which means that if the dosage is incorrectly selected, there is a risk of poisoning!

General recommendations for patients taking iron supplements for anemia
- strictly observe the dose and duration of treatment prescribed by your doctor. Do not forget that an overdose is fraught with severe poisoning;
- hemoglobin indices return to normal within 1–1.5 months from the start of therapy. Laboratory monitoring of blood counts is required.
- medications containing iron stain the stool dark, which is not a cause for concern. If you are taking a fecal occult blood test, be sure to warn your doctor about taking iron supplements, because the test result may turn out to be false positive;
- common side effects of iron supplements are: abdominal pain, vomiting, nausea, flatulence, intestinal cramps.
Achievements of modern pharmacology make it possible to rationally approach the choice of iron preparations for anemia, taking into account the indications, individual tolerance and financial capabilities of patients.
Despite a fairly wide arsenal of drugs for the treatment of iron deficiency anemia, only a doctor should be involved in the appointment and selection of drugs. Self-medication can not only be ineffective, but also lead to dangerous consequences. Treatment of anemia is a long process and requires a serious professional approach.

The reasons for the development of anemia
Anemia is a condition of the body in which there is a significant decrease in hemoglobin simultaneously with the level of red blood cells in the blood. Due to the reduction of red blood cells, the normal transportation of carbon dioxide and oxygen to large vessels, cells and tissues, and then to organs is disrupted. Signs of anemia include fatigue, sleepiness, lethargy, and even irritability.
Anemia is classified into the following types:
- by the mechanism of development;
- by severity;
- by color indicator;
- by morphological characteristics;
- by the ability of the bone marrow to regenerate.
Electric cutting scissors Electric Metal Shears Hand Tools for Cutting Iron
Mechanical anemia develops due to large blood loss or during the destruction of a significant number of red blood cells. According to the severity, there are: mild, moderate and severe anemia. According to the color indicator, anemia is divided into: hypochromic anemia (weak color of red blood cells), normochromic (medium color) and hypochromic (excessive color).
Rating of the TOP 7 best iron supplements for anemia
In pharmacies, you can find a huge variety of medicines and vitamins that contain iron. Of course, it is better to consult a doctor before buying. But we still analyzed the effect of each drug and made a list of the best. Our TOP 7 rating includes the following:

I took the drug during the first and second pregnancies. To maintain a normal iron level, it is enough to take 1 tablet a day. In the first pregnancy, Ferroplex endured well. In the second pregnancy, after a 2-week intake, she felt a sharp decrease in appetite, after which she stopped taking it. Otherwise, the state of health was excellent.
How to take it right
The correct intake of the drug and the dosage is prescribed by the doctor after examination and the delivery of the necessary tests (complete blood count and biochemistry). Some antibiotics and medications can slow down the action of iron supplements and need to be stopped or replaced with others on the advice of a doctor.
Usually, ferrous iron preparations are taken on an empty stomach before meals. In the instructions for each drug, the time of administration and dosage are strictly prescribed. These recommendations should be followed. If the composition includes sorbitol, vitamin C and folic acid, then the drug will be absorbed faster. For a complete treatment, you need to add foods containing iron to your diet. These include meat, seafood, pears, apples, plums, bananas, tomatoes, bell peppers, cucumbers, carrots, cabbage and kefir. Conversely, exclude cola, chocolate and coffee.
Self-treatment is prohibited, even for preventive purposes!
Iron is an essential element of our health. One of its most important properties is blood oxygenation. Due to various circumstances, both men and women may experience iron deficiency, which leads, in addition to a general deterioration in well-being, to problems with the skin, nails, and hair condition. complex cases are characterized by a lack of oxygen in the body, weakness, tachycardia, and many other symptoms. Fortunately, this problem is completely solvable and normal iron levels can be restored with the help of special preparations.
We bring to your attention another small list in which we have highlighted the best representatives of the pharmaceutical preparations that replenish the lack of iron in the body. It includes the best in the categories:
- the most popular;
- for pregnant;
- for children.
Safety when working with scissors
Safety precautions when working with a tool such as scissors is very important, because they are among the piercing-cutting objects, which means that if they are mishandled or mishandled, they can be quite dangerous. For this reason, it is very important to understand what safety rules should be followed when using such items in everyday life.
Scissors and children
Any object in children’s hands can be dangerous, first of all, for the child himself. For this reason, before giving the scissors, you need to explain the baby how to behave when using them.
He must firmly remember the safety rules and always follow them. Despite the fact that children’s scissors are not as dangerous as adults, you can harm yourself with them. Toddlers often love to play with all the materials at hand, and scissors are not an object that can be used for this purpose. There are also some requirements for adults who teach children how to use a new instrument.
Children at first should not be left unattended when working with scissors. Left alone, the guys can forget all the rules and hurt themselves: if you don’t cut yourself, then pinch your skin, which is also very unpleasant. And that’s not the worst thing.
Any play with sharp, cutting or stabbing objects is potentially hazardous and care should be taken to ensure that children only use the scissors for their intended purpose.
In addition to mastering the safety rules, you also need to teach the child to hold the instrument correctly. The first step to this will be special exercises that will help develop the child’s hand-eye coordination, which is necessary for safe and correct use of this instrument.
There are several such exercises, and they are all effective in their own way. To develop strength in children’s hands, you can use the following method: fill a simple rubber toy with water and ask the child to squeeze it out. The kid will surely like this exercise, which makes it possible to splash water with impunity.
Another option is to invite your child to make holes in the paper using a hole punch. You can take a curly hole punch that makes flowers, hearts, or something else. This will interest the child more. This exercise also contributes to the development of the required strength.
Do not forget about finger games for the development of motor skills and coordination.
Safety when working with scissors is explained back in kindergarten, when kids first pick up this tool. But later, few people remember them, and the very realization that scissors can be dangerous disappears. An adult treats them casually, believing that only small children can get hurt by them. But far from it.
Adults are more likely to receive domestic or industrial injuries, and the reason lies precisely in the neglect of seemingly simple objects and actions. But it is these familiar objects that often cause trouble. These items include scissors.
In fact, the rules for working safely with this tool are quite simple and easy to follow. Below are all possible cases in which the handling of scissors becomes quite dangerous.
- Do not leave scissors with open blades, otherwise there is a risk of accidentally hitting them and getting injured.
- You can not cut on the go, in the process of movement. Does it seem scary to cut off a piece of paper, cloth, or whatever while walking? A step takes less than a second, what can happen during this time? However, there is a chance of stumbling, stumbling, and this already creates a traumatic situation.
- Do not hold scissors with the blades up. The reason lies in the same aspect as in the previous case. No one is immune from accidents, and sharp blades and the ends of scissors directed towards the eyes and other vulnerable parts of the body can lead to serious injuries.
- When working with scissors, you need to monitor where the fingers of your left hand are. At the same time, it is important to choose the right length of the tool. too long an option will constantly expose a person to danger.
- You can’t run with scissors. Children, for example, are more disciplined in this regard, because they take on faith the words of their parents or caregivers and follow them. Adults are much less reliable in this respect. For example, the phone rang, which is somewhere in a bag at the other end of the room. The person accelerates towards the phone and suffers an avoidable injury. This is dangerous not only for the person in whose hands the tool is, but also for those around them, because scissors stuck from a run into any part of the body are unlikely to please anyone.
- Scissors should be passed only closed, rings forward.
- Do not leave tools on the edge of the table so that any end of them is in “free flight”.
- You need to cut in the upward direction, away from you.
- If the scissors are suddenly dull, their hinge has weakened. it is better not to work with them.
These rules especially apply to those who work with especially sharp instruments. hairdressers, surgeons, tailors. These specialists often have really dangerous items in their arsenal, and scissors are one of them.
Of course, it is difficult to imagine a surgeon swinging scissors during an operation or running somewhere with them. But with hairdressers, tailors, anything can happen. Many women come to the salon with their children, who, while their mother is doing their hair, run around the room in an effort to entertain themselves and somehow pass the time.
If you do not calm them down, then it can end quite badly. After all, a child can simply accidentally push a master who has sharp scissors in his hands.
All situations that can occur at this moment are described in the safety precautions. Upward-pointing tips. risk of eye damage. Cutting in motion can harm the client. Incorrect transfer of the scissors. risk of injury or injury to the recipient of the tool.
There is no need to expose yourself to danger and neglect safety precautions, no matter what seemingly harmless object it touches. This is a matter of safety not only for personal, but also for those around them.
How to teach children?
It is equally important to teach your child to hold the scissors correctly. It will also keep him safe from accidental injury and damage. Developmental exercises will prepare the child’s hands for working with this tool, after which you can start practical exercises.
If the child took the scissors in his hand, then the thumb should be pointing up. One of the rings is put on the finger. The middle finger is threaded into the other ring, the index finger is placed over the ring. Nameless and pinky fingers should be bent.
The correct use of the tool and the observance of safety measures will make the use of scissors less dangerous. This applies equally to adults and children. After all, if children use special scissors that do not differ in sharpness, while being created taking into account that a child will use them, then in adults the tool can be as dangerous as possible.
Sharp blades, sharp edges, and careless safety practices all combine to put people at risk of injury. To avoid this, it is enough to follow simple rules and do not forget that, despite their everyday life and habit, scissors are a potentially dangerous item that must be handled very carefully.
