Everything you need to know about stationery knives. Unfamiliar familiar objects: a clerical knife How a clerical knife works

One of the modern tools that is used in repair or construction, or just in the office, is a clerical knife. This is a unique type of knife that has a narrow specialization, but at the same time, a wide range of uses. In this article we will talk about what this tool is for, how to buy a stationery knife and what you need to look for when buying.

Appointment of a clerical knife

The tool is needed primarily to cut paper, cardboard or plastic. Therefore, it is very often used in the office or in the repair of premises, apartments and houses. In the office, with its help, you can cut paper much faster than with a knife, in the same way, handling cardboard or any other stationery material. During repairs in an apartment, for example, in order to glue the wallpaper on the walls or ceiling, it is necessary to properly adjust the wallpaper, cut it out, and work with it. Therefore, in such cases, a clerical knife is also used.



The advantage of using a clerical knife as opposed to a knife, for example, is the following point. When using scissors, it is necessary to make constant movements in order to move / move apart the scissors blades. This leads to the fact that during the cut, wavy cuts and irregularities can remain on the surface of the paper. But in the case of using a clerical knife, such a moment is excluded. Yes, there is a possibility that using a clerical knife, the cut line may also be uneven, but not as much as it is with scissors. Thus, the clerical knife is more convenient and easy to operate in most cases.

Also, with a clerical knife it is very convenient to level the glued wallpaper, which has "tails" at the bottom. It is almost impossible to trim these tails with scissors. Using a clerical knife - this is done in one motion.

Design and features of the tool

Like any other knife, a utility knife consists of a handle and a blade, however, in this case, the blade is retractable, and therefore you can set its overhang to any convenient length. By the way, the rest of the blades for a clerical knife can be hidden in the handle - so, removing the back cover of the handle, you can find a small compartment with spare blades. However, this is not the case with all knife models.



The knife body itself can be made of plastic or metal. In addition, these materials can even be combined with each other. The surface of high-quality office knives, as a rule, is also rubberized for more convenient work with the tool. Index finger notches and other design features may also be present.

But, the main attention when buying a tool is to pay attention to the blade. The result of working with the tool will largely depend on how well and responsibly this part is made. So, a quality blade should be made of durable, stainless steel. There should be several marks on the surface of the blade, which indicate its division into special sections. With the help of these sections, you can extend the knife to a certain length, and on the body itself there must be a device with which you can fix or hide the blade.

Also, before buying a clerical knife, you should definitely know the length of the knife, because its purpose will depend on it. For one type of work, a small knife will be enough for you, for others you will need a knife with a sufficiently long blade.

Consumer analysis of stationery knives

Therefore, in this material it is worth highlighting the highest quality, and at the same time, affordable stationery knives that will definitely not let you down.

The stationery knife is a versatile modern tool that has found wide application during repairs, construction work, and just in the office. But even such a common and seemingly uncomplicated instrument has its own secrets that you need to know.


A stationery knife is a common tool with which you can conveniently and with minimal effort cut paper, cardboard and even plastic. This tool will come in handy during repairs in an apartment. So, a clerical knife will become worthless salvation when it is necessary to adjust the wallpaper when gluing walls and ceilings, or to align the "tails" of already glued wallpaper. Moreover, after using a clerical knife, no wavy cuts and irregularities remain, as when using scissors.


The cavity in the knife handle that stores the spare blade

The body of an office knife is usually made of plastic or metal. In addition, high-quality tools can be rubberized, which makes them more convenient to use.

But the main detail to look out for when buying is the blade. It should be made of strong steel, and a device should be located on the body of the tool that allows you to fix the extended blade or, on the contrary, hide it. The blade must be broken off as it dulls.


If the blade of a stationery knife is over, do not rush to the store for a new one. Some models have a cavity in the knife handle that stores spare blades.

Why do you need a gap on the back cover of a knife, or how to break off a dull blade correctly

Sooner or later, the blade of a clerical knife becomes dull. To restore the functionality of the tool, it is necessary to break off the blade along the oblique mark on the surface of the blade. But not everyone knows how to do this conveniently and safely. This is where another secret of the clerical knife comes in handy - an inconspicuous gap on the back cover of the handle.


The blunt edge of the knife blade must be placed in the slot on the removed cover. The tool must be held in hand so that the blade is facing up with the side where there are no dividing marks. After that, you need to bend the blade along the break line FROM YOURSELF. In this case, the blunt debris remains in the slot of the cover, and the tool again becomes suitable for full-fledged work.

It remains to be noted that the most seemingly familiar things have their secrets. Not all even the most ardent sushi fans know. And this is a very important secret!

Of course, there is nothing special in the clerical (wallpaper) knife, and before the finishers completely dispensed with the clerical knife. In order to cut or cut something, a special cutter knife was used. Many finishers use it today. For the manufacture of wooden shabashki when exposing windows, doors, elements of a wooden frame, a cutter is used more often than an ax or a chisel. And this is perhaps the only area of ​​application of the cutter knife, where it is not desirable to use a wallpaper knife, but it is possible. Nevertheless, a conventional cutter, like any other cutting tool, has one drawback - the knife gradually becomes dull during operation and it has to be sharpened periodically. Not that it is very difficult or expensive, but it takes time to sharpen the tool, and a good electric sharpener will not hurt.

The blade of a wallpaper knife dulls in the same way, and sometimes faster than that of a conventional cutter, but since the blade of a wallpaper knife consists of relatively easily breakable sections, and the blade is also replaceable, the problem of bringing the knife into a combat state is solved in a few seconds.

Of course, clerical knives, and even more wallpaper knives, are different, but here we are talking only about one type of knife with replaceable blades 18 mm wide. Such knives are simple, with a plastic body, and reinforced, with a metal body protection:

A simple knife is shown on the left, reinforced (hardened) on the left. And although the photo shows far from all possible models of wallpaper knives, nevertheless, all such knives have replaceable blades with notches for breaking off individual sections (1), there is a button for extending and retracting the blade (2) and a latch for fixing the extended blade 2 (1), for reinforced models, this may be a twist, not a latch. For simple knives, the back part (3) is usually removable, it is removed to replace the blade or to break off a dull section of the blade. Some knives even have a hole in the body so that you can hook the knife onto the mounting belt. Both models in the photo have such holes.

Replacement blades for wallpaper (stationery) knives are sold in a set of 10 pcs. Such a kit costs $ 0.15-0.2. However, the knife itself rarely costs more than $ 0.3-0.5.

How to gently break off a utility knife blade?

Sometimes on sale you can find a stationery knife at a price of $ 0.2, and there are reinforced knives at a price of $ 1-2 and more. In general, reinforced knives are more reliable and last longer, but it is more convenient for me to work with a simple knife, although there are knives with metal reinforcement in the household. Somehow it turns out that at the right moment there is no wallpaper knife at hand, and it is easier and faster to buy it than to search, therefore, if you dig well in the tools, you can dig up a dozen different wallpaper knives, and maybe more. Simple knives are less reliable because the plastic latch 2 (1) sometimes breaks, and the back part (3) also sometimes breaks off.

To break off a dull section of the blade, you can use the detachable back piece (3), or you can use pliers. And if the blade is completely dull, and this often happens when cutting polyurethane foam near concrete and plastered surfaces, then it is better to completely change the blade.

The blade of a clerical knife is very thin, so you need to work with the knife carefully so as not to break the blade ahead of time. During operation, the blade extends to the required length and is fixed with a latch or twist, and when the knife is not needed, the blade is pushed into the body, thus minimizing the risk of unnecessary damage and cuts not only to building materials, but also to humans. For most of the work, it is enough to extend the blade 1-1.5 cm, and only for cutting foam, foam rubber and polyurethane foam, the blade sometimes has to be extended to its full length.

Of course, it is absolutely not necessary to use a clerical knife when performing finishing work. Wallpaper can be cut with scissors, linoleum or carpet - with a special knife, plastic panels, polystyrene, drywall - with a jigsaw, electrical wires can be cleaned with special pliers (stripper, crimper, etc.), but only all this makes sense when doing work professionally, i.e. e. constantly and in large volumes. And when performing repairs in your apartment, a clerical knife can replace a whole set of tools with a volume of up to 0.2 m 3, weighing up to 200 kg and a price of up to $ 1000. This is such a tool - a clerical knife.

How to properly break off a utility knife blade

Every time I break off a dull segment of a stationery knife, I unconsciously cringe - after all, there is a possibility that the fragment will fly into someone's eye (me, for example). It turns out that the creators of the tool foresaw this nuance.

The fact is that in the cap of any knife there is a special notch, and you need to update the blade like this.

Only extend the blade one segment, not as shown in the photo, then it will break in the right place. The shard will remain in a recess from which it can be safely removed.

How to Pick a Good Stationery Knife

A couple of decades ago, no one knew anything about this instrument. It has not yet been invented, in general. But now ask any adult and even a child and he will say what it is. In our article, we decided to describe the distinctive features of the various types of this tool, so that you can choose a high-quality and convenient one.

Structurally, a clerical knife consists of a body, a blade and a blade fixation mechanism. Also, some models have some "bells and whistles" that increase the reliability, strength and durability of the knife.

To begin with, we note that all stationery knives vary in size depending on the width of the blade. There is on sale 3 blade sizes: 7mm, 9mm and 18mm. The blades of these knives have a distinctive feature. Along the entire length of the blade, at regular intervals, there are grooves at an angle to the axis of the blade. This is done to quickly "sharpen" the blade. When the blade becomes dull in the process of work, with the help of pliers the dull piece is broken off along the groove and the knife again becomes as sharp as new.

Similarly, you can sharpen a knife 4-5 times. After that, the blade becomes too short and needs to be replaced with a new one.

A utility knife with a 7mm blade is used exclusively for cutting paper. It is difficult to cut a denser or thicker material with its help, primarily due to the fact that the blade is thin enough and when cutting it bends and the cut turns out to be curved. A knife with a 9 mm blade is the most common. It can be used to cut paper, cardboard, thin leather, plastic and much more, up to linoleum.

By the way, this knife is very widely used in construction. It's just that it can be used for both household and construction purposes - as they say, "with one blow of two birds with one stone." Well, the largest clerical knife with a blade 18 mm wide is already exclusively a construction knife and has nothing to do with clerical affairs.

The next element that differs from model to model is the retainer. On small knives, it is completely made of plastic and looks like a sliding element. When it is spread, the blade is fixed, when it is shifted, the blade can be moved along the body. However, in good knives, the retainer is made in the form of a twist with a pressure plate. This type of lock is more reliable, since the screw is made of steel and is more durable than the plastic element. If you buy a tool not just once, but for many years, choose a screw lock.

And finally, one more element that you should pay attention to when choosing a clerical knife is the tip of the case from the side of the blade.

Secrets of a stationery knife that will extend its service life many times over

In cheap models, the body is completely made of plastic, and in expensive and good ones, a metal element is built into the tip of the body, inside which the blade moves.

This element provides additional rigidity to the blade when cutting hard materials, which prevents the blade from bending when applying significant forces. For those types of stationery knives that are used in construction, this is very important, since they do not cut thin paper there, but durable plastic, linoleum and similar materials.

We will not dwell on the features of the shape of the case. Let everyone here choose for themselves. But remember that very convenient ergonomic casing of stationery knives significantly increase the cost - several times. If you are ready to spend a lot of money for such convenience, please, and if you just need a reliable tool, just take a model with a democratic price but taking into account the nuances described above.

How to choose a stationery knife? And then what to do with it?

Stationery knife - a kid who becomes a good helper at home or in the office. Most of the objects we use in life have an interesting history. But we rarely think of her. The stationery knife is no exception, so we simply could not remain silent about it.

In the form in which we are used to seeing a clerical knife, it appeared not so long ago, approximately in the middle of the twentieth century. But his great-grandfathers existed much earlier, but had a different appearance. Previously, a clerical knife was used only for opening letters, this was treated as a ritual, so a letter opening knife was more of an accessory than a household item. When

stationery knife

brought on a silver platter along with fresh letters (you already feel this luxury, right?), the knife was decorated with precious stones, gold and silver. But times have changed, boasting about a knife is no longer necessary, so the paper knife has changed. Now the stationery knife looks like we are used to, but has more purposes and types. We will tell,how to choose a clerical knife and what to do with it in general!

What to look for when choosing a stationery knife:

Body material

The material from which the body of the stationery knife is made is plastic or metal. The first, of course, has a lower cost than metal. But both of these materials have their pros and cons. The metal body of the knife will last much longer, because plastic has never been famous for its durability. But a plastic knife will be lighter. The metal body is also good in that it firmly protects the blade and makes the knife safer. If you have not heard the stories that plastic sometimes broke in the hands of a person, and the blade dug mercilessly into the hand, then you are in luck. But this only applies to low-quality plastic, where manufacturers save on material.

Blade width

The blade in office knives comes in different widths:

7mm

9 mm

18 mm

Different blade widths are suitable for different types of work. At this point, we will make a break and tell you more. A utility knife with a 7mm blade is only suitable for paper, but if you want to cut cardboard with such a knife, this idea is doomed to failure. In this case, either the blade will not withstand the load, or the cut turned out to be like tearing that unfortunate cardboard with your hands.

9mm bladeuniversal, both in the office and for construction. Such a clerical knife perfectly cuts paper, cardboard of different densities, copes with light loads in construction.

A stationery knife is a very useful thing in any household, it not only brings practical benefits, but also helps to create real masterpieces. This tool is essentially a small gadget that is easy and convenient to carry with you. In addition, you can easily replace the blade if the previous one has become unusable.

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

A bit of history

If we talk about when and why these knives appeared, several interesting facts can be noted.

For example, the original application of this device was to open letter envelopes. In those days, when most of humanity communicated remotely using paper messages, there was a very shortage of a thin and sharp knife for conveniently extracting a letter from an envelope.

When such appeared, the integral design of such a knife was not devoid of flaws. It was a sharp and thin blade, but the problem began when it became blunt - how to sharpen it as perfectly smoothly and functionally was absolutely incomprehensible.

In the middle of the twentieth century, a Japanese inventor decided that it would be more correct to make the blade removable. Today, with such a clerical knife, you can easily break off a blunt piece, replace it and continue working with a new and sharp one.

The idea was embodied in production and was so accepted by users with a bang that the inventor even created OLFA, which produced stationery knives.

Features and Benefits

We can talk about the convenience of this device for a very long time, comparing it with its older big brothers. But for each tool there is a niche, the stationery knife is firmly based in its own.

  • It does not require sharpening, you can buy it once and use it for a very long time, just changing the blade if necessary. This eliminated the need for additional maintenance hassle for the owners.
  • Undoubtedly, one of the main features of modern design is the ability to adjust the length of the working part. Holding on to a plastic or even wooden handle-holder, you can independently extend the tool to the required length in order to use it as efficiently as possible.
  • Wide range of applications. Once upon a time, it was, indeed, kept in a desk drawer to open envelopes with. But today you can cut the wallpaper with this knife, strip the wire, modify some element of the sculpture, or use it for any design solution.

Views

Initially, there was only one type - the classic. But over time, many variations of stationery knives began to be produced, corresponding to the needs of users.

The handles of these tools are made from different materials, and the blades are also different. In addition to these differences, the cutting element can be wide or narrow. Different widths allow for a variety of use cases.

It is worth noting that a knife with a plastic handle is cheaper. But the structural strength itself leaves much to be desired. Sometimes the structure can just crack or just very unpleasant to "play" in the hand, which definitely leaves an unpleasant impression on the work. Therefore, experts recommend paying more attention to metal products.

Such knives are pleasantly heavy in the hand, break less and less often, and are safer and more comfortable to use. There are even some aesthetic options with a wooden body. True, they are more suitable for the interior of an expensive office, but if you like such a thing, then why not. Convenience is just as important as practicality.

Which option will be yours depends entirely on where and how the tool will be used. For example, if your task is more related to repairs, and especially to work with wiring, then you should not choose a knife with a metal handle. It is safer to use a wooden or plastic frame.

In the case where paper handling is required, it is understood that this is a reusable and frequently used option. Therefore, the body can have a beautiful shape and color, and the point itself can be incredibly sharp and small.

In addition, in the case of cutting wallpaper or other similar materials, the option with a twist lock is perfect. Usually the latch is flat and can be accidentally moved during use. But in the case of a twist, a more reliable design is obtained, because in order to move the mechanism, it will be necessary to cope with this very twist.

There are also options for everyday construction site use. These are more professional tools that have a special (usually rubberized) grip and a more durable wide point.

Since the range of application of stationery knives is very wide, there are different proposals for this demand. You can choose from a large or small instrument, with a wide variety of fixation solutions, as well as with different tip widths.

There are even small gadgets no bigger than a pen. Such a compact design is convenient to carry, and its sharpness is perfect not only for ordinary tasks, but also for cutting photographic paper. Today a mini-knife is bought more and more often, since a larger user often does not need it.

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

Selection rules

To get the maximum benefit and even enjoyment from using a clerical knife, no matter what you need it for, it is important to pay attention to its blade.

  • 7 mm wide and less is ideal for using the knife for its intended purpose, whether it is cutting thin paper or sharpening a pencil. This option is not suitable for any construction work, it will not even be able to cut the wallpaper correctly the first time.
  • 9 mm blade is, in principle, a universal and most frequent case, it is precisely the very same tool-helper in any area. If you don't have a clear preference for the application, then this is a great option for you.
  • Wide blade 18 mm wide usually comes in a large rubberized case and does an excellent job not only with wallpaper, but also with wires. Simply put, it is a great choice for renovation work.

To choose a knife individually for yourself, first of all, decide on the scope of use, depending on which you should pay attention to large or small blades. If this issue has already been resolved, just take the knife in your hand. And if it lies comfortably, you like it by the sensations, it is firmly fixed, then this is your choice.

If you want to please a loved one or a colleague, you can purchase not only a beautiful knife, but also a whole gift set. Often a stylized set of pencils, pens and other stationery goes to such a knife.

Before buying, make a test cut on the paper to make sure that the functionality is fine for you.

A stationery knife is an indispensable thing in the household of real housewives and needlewomen, who know how to create beauty with their own hands. This small but incredibly practical and multifunctional tool able to easily work miracles in your home. It is a small knife with a folding blade, which, if necessary, can be easily replaced with a new one.

Initially, its main purpose was paper cutting. But very quickly such a convenient tool significantly expanded the scope of its application and is now considered almost the most necessary, in fact, irreplaceable thing, both at work and at home.

History of invention

Such a convenient multifunctional tool was officially invented not so long ago - in the middle of the 20th century. But its simplest predecessors existed in the 17th-18th centuries. and were used by Europeans to open received letters. Modern version with replaceable blades invented by the resourceful Japanese Okado.

The main goal of the inventor was to create a practical paper cutting tool that could be used successfully for a long time without the need for sharpening. Okado succeeded in fulfilling his desires wonderfully, because the knife he invented has found wide application in various fields of activity. The same Japanese also created the first company for the production of stationery knives - "OLFA" (abbreviation for the combination of "breaking off fragments"), which still remains iconic brand.

Advantages

All in one

This simple tool is popular with both office workers and professional craftsmen in the field. design, construction and repair. But in the house, he is able to replace a number of similar, but often quite expensive instruments. This is the main advantage of the clerical knife. They can cut wallpaper and polystyrene, linoleum and drywall, cut pictures from paper and strip electrical wires. For all these works, you can use special tools, but within the framework of single manipulations it is more economical and more convenient to use a clerical knife.

No sharpening

Usually, any type of such knives is produced with special cutoffs on the blade, allowing you to easily break off the blunt part and continue to use the same reliable tool. The simplest models are equipped with a removable part that allows you to easily replace worn out blades. All this provides perfectly accurate cutting of any elements.

Security at the highest level

When working, you can always choose the most successful blade length, which is provided by a special regulator. By means of the latch, the favorite position can be securely locked, which guarantees maximum safety. Unexpected loss of the sharp part is simply out of the question. Special metal guides provide good resistance to increased loads and eliminate the likelihood of injury.

Types of stationery knives

There are many different variations, but most common 2 types of their classification:

  • by body material;
  • across the width of the removable blades

It is these parameters that are taken into account in the first place when choosing such a thing that is useful for the home.

Body material

Plastic is valued cheaper than metal, but a significant disadvantage of such a case is fragility, as well as a high probability of sudden chips and injury. Therefore, if you want to purchase a safe knife, it is better not to save money and opt for a metal case. This type of tool will be reliably protected from the blade, which guarantees a minimum risk of injury when working with it.

Blade width

Blade width it is worth considering, focusing on the type of work, since excessive loads when choosing the wrong type are fraught with damage to the tool and possible injuries. A 7 mm stationery knife is suitable for cutting decorative figures and various decorations from paper, but this is a completely unsuccessful option for working with wallpaper.

There are three most popular types of blade widths: 7, 9 and 18 mm. The 7mm knife is only suitable for cutting thin paper. Such a knife will either not cope with thick cardboard at all, or it will leave oblique cuts and holds. 9 mm knife considered universal for use in many construction and finishing works, but can also be used as a stationery. It cuts well both thick cardboard and thin leather and even linoleum. An 18 mm knife is called a construction knife, since it is used exclusively in such works.

Right choice

You can buy a knife at any office supply store. If, for your purposes, work not only with paper, then in the store of building materials and tools you can buy a large knife, which is ideal for working with wallpaper. First of all, you should focus on your goals for using a clerical knife. But when choosing such a tool, it is also important to take into account other important nuances.

  • The knife should fit comfortably in your hand. Therefore, it is important to choose the model that is suitable for you in terms of weight and dimensions.
  • The knife should be safe for you. Therefore, it is important to make sure that the blade feed mechanism is working properly, which should slide out easily and smoothly from the body.
  • The blades must be made of high quality stainless steel, otherwise they will simply become unusable very quickly.
  • Plastic clips can break quickly. Therefore, it is better to choose a model with reliable screw fixings.
