The stationery knife is a kid who becomes a good assistant at home or in the office. Most items that we use in life have interesting story. But we rarely remember about it. The stationery knife is no exception, so we just could not keep silent about it.

In the form in which we used to see the stationery knife, it appeared not so long ago, approximately in the middle of the twentieth century. But his great-grandfathers existed much earlier, but had another appearance. Previously, the stationery knife was used only to open letters, they treated it as a ritual, therefore a knife for opening the letters was more like an accessory, not a household subject. When they brought on a silver dish with fresh letters (already feel this luxury, yes?), The knife was decorated precious stones, gold and silver. But the time has changed, it became not necessary to praise the knife, so the paper knife was changed. Now the stationery knife looks like we are accustomed, but has more destinations and species. We will tell how to choose a stationery knife and what then to do with it!

To pay attention to when choosing a stationery knife:

Corps material

The material from which the housing of the stationery knife is made is plastic or metal. The first, of course, has the cost below than the metal. But also in the other material there are pros and cons. The metal body of the knife will serve much longer, because plastic has never been famous for durability. But the plastic knife will be easier. The metal case is good for the fact that it firmly protects the blade and makes the knife safer. If you have not heard stories that plastic sometimes broke in the hands of a person, and the blade mercilessly dug in the hand, then you were lucky. But this applies only to poor-quality plastic, where manufacturers are saved on the material.

Blade width

The blade in the stationery knives is of different widths:

Different blade width is suitable for different species work. At this moment we will make a halt and tell you more. Stationery knife with 7 mm blade suitable for paper only. If you want to cut the cardboard with such a knife - this idea is doomed to failure. In this case, or the blade will not withstand the load, or the cut turned out to be such an unfortunate cardboard.

The blade of 9 mm is universal, both in the office and for construction. Such a stationery knife exceeds paper, cardboard of different density, copes with minor loads in construction.

But a knife which has 18 mm blade width used only in construction workAfter all, for home and office, he is too big and there is no such heavy loads there.

When technical issues figured out, now we will promote further and deeper to know how to choose the right knife.

Rules for choosing a stationery knife:

The stationery knife is not just choosing office workers, builders and even people whose activities are related to creativity (let's talk about it a little later). All because the stationery knife has several advantages with which other knives are difficult to compete.

Advantages of the stationery knife:

• One instead of a dozen. It will be difficult to cut the foam or an extra piece of wallpaper by ordinary scissors, because it will not be exactly. Also uncomfortable butter knife cut out color paper flowers. The stationery knife is applied in different areasSo, so as not to buy dozens of different knives, you can buy only one!
• Does not require sharpening. Always demand sharpening, because the sharpening has become not eternal, unfortunately. So, the stationery knife does not need to be sharpened. When the blade fits, it needs to be simply broken across a special mark. Then the knife will become the same sharp as he was at the beginning.
• Safety . What incapsions happen to ordinary knives or scissors, we will not tell, and then suddenly want to check. The stationery knife is safe. You can adjust the length of the blade that is necessary for certain actions. The mechanism tightly fixes the blade in the housing, so the chance that it falls and hurts the hand - zero.

So the article was so quiet to the second question: what to do with the stationery knife after we chose him and bought?

Application of a stationery knife:

Stationery knives can be found in desktops, but often this small assistant is forgotten and postponed into the far box. But why? Instead of leaving uneven cuts by ordinary knives and scissors, you can simply take advantage of the stationery knife. All smooth cuts and safe knives!

Stationery knife - very useful thing In any farm, it not only to make practical benefits, but also helps to create real masterpieces. This tool is essentially a small device that is easy and convenient to carry. In addition, it is possible to replace the blade without much difficulty if the previous one has become unusable.

The stationery knife was once invented in order to use it for cutting paper. However, the more time passes, the wider the scope of application of this wonderful device becomes.

A bit of history

If we talk about when and why these knives appear, you can note a few interesting facts.

For example, the initial use of this device was the opening of envelopes with letters. In those days, when most of humanity communicated remotely with the help of paper messages, there was not enough thin and sharp knife for convenient removal of the letter from the envelope.

When such appeared, the holistic design of such a knife was not devoid of flaws. He was a sharp and subtle blade, but the problem began when it was tupped - how to sharpen it as perfectly evenly and functionally, it was strongly incomprehensible.

In the middle of the twentieth century, one Japanese inventor decided that it would be more correct to make the blade removable. To date, if you have such a stationery knife, you can easily break down the smoking piece, replace it and continue to continue working with new and sharp.

The idea was embodied in production and turned out to be so accepted by users with a bang that the inventor even created an OLFA company that produced the stationery knives.

Features and advantages

You can talk about the convenience of this device for a very long time, comparing it with older large brethren. But for each tool there is its own niche, the stationery knife was tightly founded in his.

• It does not require sharpening, you can buy it once and use for a very long time, just changing the blade in need. It saved the owners from the need for additional sales.
• Undoubtedly, one of the main features of modern execution is the ability to adjust the length of the working part. Holding behind a plastic or even a wooden-handle, you can independently push the tool to the required length to use it as efficiently as possible.
• Wide scope of application. Once upon a time it was really stored in the table box to open envelopes with it. But today you can cut off with this knife wallpaper, clean the wire, modify some kind of sculpture or apply for any designer solution.

Views

Initially, there was only one species - classic. But over time, it began to produce many variations of the stationery knives corresponding to the needs of users.

Handles of such tools make from different materialsThe blades are also different. In addition to these differences, the cutting element can be wide or narrow. Different width allows you to diversify the scripts of use.

It is worth noting that the knife with a plastic handle is cheaper. But the strength of the construction leaves much to be desired. Sometimes the design can simply crack or just very unpleasant to "peel" in hand, which uniquely leaves unpleasant impressions of work. Therefore, experts recommend paying attention to more on metal products.

Such knives are pleasantly heavy in hand, less and less break, safer and more comfortable in use. There are even individual aesthetic options with a wooden case. True, they are more suitable for the interior of an expensive cabinet, but if you like such a thing, then why not. Convenience is no less important than practicality.

What kind of option it becomes exactly yours depends entirely, where and how the tool will be used. For example, if your task relates more to repair, and especially with wiring, then you should not choose a knife with a metal handle. Safer will use a wooden or plastic frame.

In the case when working with paper is required, it is implied that this is a reusable and frequently used option. Because the case may have beautiful shape And coloring, and the tempting itself is incredibly sharp and small.

In addition, in the case of cutting wallpaper or other similar materials, the option with a twisting retainer is perfect. Usually the retainer is used flat, and it can be randomly moving when operating. But in the case of the twist, it turns out a more reliable design, because in order to move the mechanism, it will be necessary to cope with this twist.

There are also options for daily use at a construction site. These are more professional tools that have a special (usually rubberized) handle and a stronger wide edge.

Since the spectrum of the application of the stationery knives is very wide, then there are different suggestions on this demand. You can choose a large or small tool, with the most different decisions of fixation, as well as with different widths of the island.

There are even small adaptations of the magnitude of no more handle. Such a compact version is convenient for wearing with you, and its acuity is perfectly suitable not only for ordinary tasks, but also for cutting photographic paper. To date the mini-knife is purchased more and more often, since the larger user is often not needed.

To get even more functions in one cutter, you can purchase an option with a pencil sharpener. And in general, you then open two sharpening options at once: the blade itself or a special sharpener.

Choice rules

To get the maximum benefit and even pleasure from the use of a stationery knife, for what it would be needed to you It is important to draw attention to his blade.

• Width in 7 mmand less ideal for using a knife for direct purpose, be it cutting a thin paper or a pencil sharpening. This option is not suitable for any construction work, it will not even be able to correctly cut the wallpaper from the first time.
• Top view of 9 millimeters It is in principle universal and most frequent occasion, it is also the tool assistant in any area. If you do not have clear preferences regarding the scope of application, then this will become an excellent option for you.
• Wide blade in 18 millimeters width Usually comes in a large rubberized case and perfectly copes not only with wallpaper, but also with wires. Simply put, for repair work this is an excellent choice.

To find a knife individually for yourself, first of all decide on the use of the use, depending on which it is worth paying attention to large or small blades. If this question is already resolved, just take the knife in your hand. And if it is comfortable lies, you like it feeling firmly fixed, it means that this is your choice.

If you want to make a pleasant near man Or colleague, you can buy not only a beautiful knife, but also a whole gift set. Often to such a knife there is a stylized set of pencils, pens and other stationery.

Before buying, make a control incision on paper to make sure: the functionality is quite suitable.

The stationery knife is a universal modern tool that has found widespread use during repair, construction work, and just in the office. But even such a common and seemingly uncomplicated tool, there are its secrets that you need to know.

The stationery knife is a common tool, with which it is convenient and with minimal efforts you can cut paper, cardboard and even plastic. This tool is useful and during repairs in the apartment. So, the stationery knife will be a handful of salvation when it is necessary to adjust the wallpaper when sticking the walls and the ceiling, or to align the "tailings" of the already cowned wallpaper. Moreover, after using a stationery knife, there are no wave-like cuts and irregularities, as when using scissors.

Cavity in the knife handle in which the spare blade is stored

The housing of the stationery knife is usually performed from plastic or metal. Quality tools can be also rubberized, which makes them more comfortable in operation.

But the main part to pay attention to when buying is the blade. It must be made of durable steel, and on the tool body must be located, which allows you to fix the extended blade or, on the contrary, hide it. The blade must be dispersed as it is fascinated.

If the blade of the stationery knife is over, you should not hurry to the store for a new one. Some models in the knife handle have a cavity in which the spare blades are stored.

What do you need a gap on the back of the knife, or how to define the blurred blade

Sooner or later, the blade of the stationery knife is blinking. To restore the functionality of the tool, it is necessary to break the blade on the inclined label on the surface of the blade. But far from everyone knows how it can be done comfortably and safely. This is where another secret of the stationery knife is useful - inconspicuous gap on the back cover of the handle.

In the slot on the lid removed, it is necessary to put the root edge of the blade of the knife. The tool must be kept in the hands in such a way that the blade is drawn to the top of the side where there are no dividing labels. After that, you need to bend the blade along the breakfast line from yourself. At the same time, the fallen fragment remains in the slit of the lid, and the tool again becomes suitable for full work.

In addition to excellent external viewThis knife is very convenient to use, it is pleasant and comfortable to hold in your hands. And when the work ended, you can fold the knife, and it will be safe. It's not difficult about it is not difficult, however, the author uses a considerable set of tools, but this does not mean that such work can not be carried out with simpler tools.

For the manufacture of a knife, you will need soft wood so that it is convenient to handle it. Suitable, for example, alder or birch. As for the knife holder, his author made a leaf aluminum. Unfortunately, the manufacturing process is not shown, but the design is quite simple. It is made from two aluminum plates that are tightened with a screw. So, let's start making a knife!

Materials and tools that used

List of materials:
- one hundredstoes;
- homemade clamp for the blade;
- screws with nuts;
- metal line or other such a segment of metal;
- small wooden lumps or similar;
- glue for wood;
- clamps;
- double sided tape;
- Oil for wood processing.

List of tools:
- drilling machine;
- vice;
- ;
- Files;
- (manual);
- sandpaper;
- a circular saw;
- ;
- Bulgarian;
- screwdrivers;
- Paper, pencil scissors for template.

The process of manufacturing a stationery knife:

Step one. Cut a rough profile
We take suitable on the size of the board and cut it into two blanks. The author decided to dissolve the board into two halves. Such work can be carried out on circular saw.

After that, you can start cutting a rough blade profile. For these purposes, we take a pattern cut out of paper and glue it to one of the blanks. For gluing the author uses bilateral tape. You can also use glue or simply bother the profile with a marker. A rough profile can also be easily cut on circular saw. The author of the wood is rather soft and very easy to handle. Also is well suited for these purposes. Lobzik.

At the end, clamp the product in the vice between two boards and modify manually using a round file.

Step second. Significant other
For the manufacture of the second half, the author used the milling machine. We glue the two-sided tape made of the previously made part to the second board. Well, then on the contour we make an identical afternoon. In this machine, there is no need for particular, you can easily make the second half exactly as the first. And you can simply cut one part, and then cut it along into two parts.

Step Three. Internal details
Between two halves of the handle, three details are installed. Two of them are in the nose, they work as an emphasis for the blade. The third part is set at the end of the handle, as a result we get the desired gap between the halves of the handles. The author makes these details by gluing.

Step fourth. We refine the handle
Drill a hole in the handle and mark, in which position will be "blade" and what will need to be removed. One half of the handle is narrower, such a profile is needed for convenient access to the blade when the knife is opened.

Having made the necessary calculations, we work on the belt grinding machine. The remaining elements the author cuts off the bit. At the end, you will need to twist the groove under the "spring-stop", this prose is just done with a milling mill.

Pitch fifth. We make a "spring-focus"
Inside the handle set metallic plate, curved up. For the manufacture of such a detail you will need steel, which springs. Great metal from the line. When the knife is in a closed state, this plate presses the blade and the knife is not disclosed spontaneously. And when the knife is completely revealed, the plate rises up and fixes the blade so that the knife itself does not close. To fold the knife, you need a finger to click on this plate.

Cut the desired detail and customize it in size to the cut-off groove. Plate screw the screw with the nut.

Step six. We glue ups
Earlier, we made three stops for the inside of the handle. Now they need to be installed on one of the halves. We use glue for wood and all are well tightened by clamps. Epoxy glue is well suited.

Step seventh. Grooves under the screw and nut head
The blade is on the axis, which uses a screw with a nut. For the parts not to be discharged over the surface of the handle, they need to make appropriate recesses. Here you will need a bit of suitable size and drilling machine. Also do not forget about the bolt that keeps the spring.

Step eighth. Finish treatment
We collect a knife, for this glue two halves with each other using epoxy glue or wood glue. Now you will need to carefully polish the handle using a ribbon grinding machine. At the end, the author handles the handle manually using the sandpaper. Gradually, moving from large sandpaper to the small, bring the product to perfect smoothness.

Wood always needs impregnation, as moisture is very afraid. In addition, impregnation makes it much more beautiful. Oil is suitable, you can use a variety. Linen, and Danish and much more suitable. The most classic option is boiled linseed oil, that is, natural olifa. When oil is absorbed into the tree, it dries up and no longer misses moisture inside.

Soak the whole handle, all those places where you can brighten. Give the handle to dry, and then you can even polish it.

Step ninth. Gunny on Klinka
In order for the knife to be conveniently revealed, holding the blade with a nail or finger, you need to make a special recess on the blade. And since instead of the blade we have a blade with a holder, the groove is cut in an aluminum holder. At first, the author is planning it with the help of a bormer and cutting circle. Then the milling machine with a suitable nozzle comes to the rescue. As a result, we get high-quality processing.

Modern version of S. replacing blades Invented the resourceful Japanese Okato.

The main purpose of the inventor was to create a practical tool for cutting paper, which could be successfully used without the need for sharpening for a long time. It was possible to implement the desired body to be glory, because the knife invented them was widely used in various fields of activity. The same Japanese created the first firm for the production of stationery knives - "OLFA" (abbreviation of the combination of "rolled fragments"), which still remains iconic brand..
