DIY switch knives. Automatic switchblade: technical specifications and latest reviews. Self-defense and possession of edged weapons Do-it-yourself frontal switchblade knife

Knives are currently popular not only in the kitchen, but also among people who have connected their lives with extreme types of active leisure - fishing, hunting, tourism, etc.

On the market in modern times available various knives: variable models, different dimensions and designs. But none of them can replace a knife that you make yourself.

People often write on the Internet about how to make a knife with your own hands, but you have to try hard to make them.

Knives: types and basic properties

In the photographs of the knife on the Internet, you can see that each product is a creative element created from various mechanisms.

There is a large classification of knives depending on their functionality: combat, tourist, folding (for example, butterfly), knives designed for hunting, multi-tools, bivouac knives, as well as ordinary kitchen knives.

Kitchen knives are bought ready-made, but knives intended for hunting or tourism can easily be made at home yourself.

There are also such knives as survival knives, the main task of which is to help in living in conditions wildlife. This option is relevant for tourists and hunters.

The blade of such a knife is usually no more than 12 cm. This length is sufficient for cutting wood, processing game, cleaning fish or other similar actions. Small dimensions make this knife easy to transport.

When making such a knife, great attention should be paid to the material intended to create the blade. Steel is often preferred.

Procedure for creating a knife

To get a positive result when making a knife, you should first sketch out a drawing of the knife. In this case, you can know in advance what exactly you want to achieve in the end.

Instructions on how to make a knife at home include a number of rules.

Making a knife step by step

Cut out the blank for the future knife. Based on finished drawing, cut out the shape for the knife.

You will need a knife sharpener. With its help, the base is brought to the required shape. And after this you will have a clear blank in your hands, where you can distinguish the places of the handle and blade.

Rough sharpening of knives. At this stage you need to clearly know what your future knife is intended for. If it is made for hunting, fishing or hiking, then it is better to give preference to the blade type of sharpening.

And, if a knife is created to function in the kitchen or in the garden, then a razor type is suitable.

Don't expect perfect sharpening at this stage, as this is just a rough draft intended to determine the future shape.

If the blade is pre-prepared, then you can start working with the handle. To create the handle, the most various materials– this is: wood, plexiglass, bones, thick types of leather, etc.

Pay attention!

Having cut out a blank to create a handle, you should check whether it fits comfortably in your hand, as well as its proportionality relative to the blade. The knife handle is secured using the riveting method.

The shape for the foot handle is given using a sharpening machine.

The knife is ground and polished using sandpaper.

The final sharpening of the blade is carried out after sharpening on a sharpener, also using sandpaper.

At the end, the finished knife is polished with velvet cloth or polish.

Pay attention!

As you can see, the process of making a knife with your own hands is not that difficult, so everyone can try their hand at this area.

You can also give the future knife the necessary and desired design. Special attention pay attention to the handle during the design process.

Knife design

Because it is by the handle of the knife that others can then judge your creative thinking and status.

Some write their names on the handles of the knife, draw certain patterns and sketches in the form of tattoos.

The simplest knife can be built in emergency situation in the forest, the main thing is to find the materials necessary to create it.

Pay attention!

You just need to find the cutting part for the knife, and then you should insert it only into the handle, which will be in the form of a piece of wood, rope or leather.

Today, buying a folding knife is not at all difficult, since such a product is not only presented in a huge assortment, it is also sold in many retail stores, as well as on Internet sites. But, despite this, every day the number of people who want to make DIY folding knife. This is due to the fact that homemade folding knives are unique and a person can customize it as much as possible to suit his preferences. Moreover, in the process self-made knife, a person can use any materials, which will make the device reliable and durable.

Before you start making your own folding knife, you need to clearly define the following indicators:

what will be the shape of the future knife;
what material will be used to make it;
what design the future knife will have;
what will be the design of the knife?

DIY folding knives can be made of any material and have any shape, the main thing is to adhere to established standards when manufacturing. When selecting materials for a knife, you must give preference to the most durable and strong material. Suitable for blade stainless steel with high hardness or Damascus steel. Of course, most people prefer stainless steel, since it is easier to make a knife from it and, unlike Damascus steel, it is resistant to corrosion.

In addition to the materials, to make a knife you need to prepare the tools that may be required during the work process. It is worth noting that during production simple option folding knife you will need the simplest available tools. Special attention should be paid to the choice of material for the handle, since it should not only be reliable and durable, but also comfortable to use. That is, you need to properly think through the shape of the handle so that it fits securely in your hand and does not slip out. Having decided on the most convenient shape of the handle, you need to choose the material from which it will be most convenient to make it.

Making a folding knife can occur using handle materials such as hardwood natural wood, impact-resistant plastic or metal. And, of course, when planning to make a knife yourself, you need to think about the mechanism for folding it. Moreover, the knife mechanisms must be treated with special care and every detail must be thought through, since an incorrectly executed mechanism can cause injuries while using the knife. Before you begin making a folding knife, you need to make sure that all the necessary materials are prepared.

Folding knife mockup

So, if a person is interested in the question, how to assemble a folding knife, then this can be done even without special skills. The main thing in this process is to take into account all the established parameters and adhere to all the rules for performing such a process. The first thing to do, starting with making a knife, is to sketch the future device on paper. You can also use special graphic editors. The most optimal options Use cardboard to cut out a template for the future knife blade, as it is more durable than paper. Moreover, you can cut out all the components of the future knife from cardboard, and then fasten the cardboard blade and handle with a screw and nut; to do this, you need to cut a hole in the cardboard for the axle. This approach will help you understand how proportional the elements of the knife are, and how the device being manufactured will close.

In addition, making a cardboard model of the knife will help to correctly match the shape of the heel of the blade, and this part, as you know, is extremely important for comfortable and practical use knife You can find out what the supporting part of the heel should look like by viewing DIY folding knife video. The video will help you make sure that the heel of the blade is really made correctly and has the required bevel angle; an angle of 7-9 0 is considered optimal. After this, you need to sketch a linear knife lock; as you know, it is based on three points that form a triangle. Each point of the linear lock has its own purpose:

for installing the pivot pin;
for mounting a corkscrew pin;
the contact zone of the supporting planes of the heel of the blade and the pressure plate, that is, the stopper.

It is worth noting that it is the lateral pressure force of the stopper that fixes the blade in the closed position; there are no other elements performing this function in this knife design. That is why it is extremely important to mount a small steel ball from the bearing into the stopper; it will become an additional lock for the closed blade and, accordingly, will secure the use of the knife. It is very important to choose the correct location of the ball lock, since it depends on the functioning of the entire knife lock.

Having marked the location of the ball retainer on a cardboard mock-up of the blade and locking spring, you need to make sure that it will fit tightly there and will not interfere with folding the knife. After this, you need to decide on the fasteners that will tighten the dies together. It is not recommended to use fasteners with large heads or place them too close to the edge of the handle. This is due to the fact that subsequently it may be necessary to install a spacer or tubular struts between the fasteners.

The procedure for making a folding knife with your own hands

Once the cardboard model of the future knife is ready and all its elements meet the standards, you can begin to manufacture the device itself. On at this stage The material for the future knife and tools that may be useful in the process of its manufacture should already be prepared. As already stated, optimal material Stainless steel is considered to be used for making a knife blade, since it will not rust even if moisture gets inside the folder.

To drill holes in hardened steel, it is best to use ceramic or glass drills. It is very important to drill at low speeds and apply a little force. If you approach the process of drilling holes in a workpiece irresponsibly, you can simply erase the drill bits without achieving the desired result. In order to prevent steel from sinking, it is necessary to constantly monitor the level of its heating and often cool the part.

As for dies, it is better to use titanium for them, since, even with a small thickness, this material has high strength indicators. In addition, titanium is lightweight and does not corrode, which is also important for a folding knife. Processing titanium and giving it the required form, it is also recommended to work at low speeds with an angle grinder; you can even use a hand hacksaw for metal.

In order to make a folding knife, the next thing to do is to cut out the contours of the corkscrew spring, which will be located at the bottom of the die. At the intended end of the die, it is necessary to drill holes with a diameter of no more than 2.5 millimeters; there should be 3-4 such holes. After making the holes, you need to connect them and put them there hacksaw blade. The next step will be sawing through the stopper line, but when performing this procedure it is necessary to leave a small margin, which will be removed during the process of setting up and checking the finished knife.

As for the lower die, it often has the same dimensions as the upper one, but there is one difference; in the lower die it is necessary to make a special recess for the hole for opening the knife. Another difference between the top and bottom dies is the diameter of the screw holes. In the lower die, such holes must be made for the screw thread, while the diameters of the holes in the upper die must have the diameter of the screw. After all the parts have been cut out and all the holes drilled, you need to make or select two small washers. Bronze or fluoroplastic washers are considered the most optimal. Such washers will act as a bearing and be mounted on the axis of rotation of the knife.

The next stage in the manufacture of the knife will be its direct assembly. This must be done one by one:

insert the axle into the lower die;
install the locking pin;
install the washer;
place the blade and assemble the knife together.

If any inaccuracies arise during the assembly process, but they need to be eliminated, for example, if the parts of the knife do not mate, then they need to be adjusted in place. After the knife is assembled, you need to install the corkscrew ball. To do this, in the area of the corkscrew spring it is necessary to drill a hole with a diameter of 0.1-0.2 millimeters, that is, it must be smaller than its ball. Medium size the bearing ball is 1.5-2 millimeters. The ball is pressed into the locking plate using a vice, and it should protrude to the surface by approximately half a millimeter.

After the ball is installed, it is necessary to determine the place of its contact with the wedge; to do this, just close and open the knife several times. After this, a mark will remain on the blade of the knife; at a distance of 0.3 millimeters from the edge of the mark, it is necessary to make a small hole into which the ball will enter when the knife is closed. In order to set and check the functionality of the knife lock, it is initially recommended to assemble the device without the top die. If everything works properly, you can completely assemble the knife and check its operation while folded.

Now the knife is ready. As it becomes clear, do DIY automatic folding knife This may take a little time and patience.

In the modern age, there are many devices that make human life easier. One of the most useful and versatile designs is rightfully considered a switchblade. The first ancestors of the model were invented in primitive times. Over time, the device has changed a lot and has become more practical and convenient. This device is truly multifunctional and allows you to perform a wide variety of everyday tasks.

History of origin

Automatic switchblades have been around for a long time, but they gained popularity relatively recently. Huge demand arose thanks to the invention of Ron Miller. It was he who created the first improved design in 1987.

The model had a high-quality modified spring mechanism. Such specimens were actively used in special army units. Although Miller did most of the work, modern knife the machine gun would not have such an attractive appearance if it were not for Charles Oke. It was he who designed the device.

Types of models

All automatic models folding knives are brought to a state of readiness thanks to a special button. When you press it, the spring mechanism is affected, due to which the blade is ejected. There are several types of automatic knives:

frontal model (the blade in this design will be thrown vertically);
knife with the principle of lateral extraction of the blade.

A knife that works on the principle of lateral ejection of the blade is often called a push-button knife. In this design, the blade is thrown out in a circle, and its center is located in the axial screw. The opening occurs thanks to a flexible spring. Front-facing models are more original; many knife lovers really like that the blade extends along the handle.

Front-end knives are the most common models of retractable knives. They are very practical and convenient. The only disadvantage of such products is the complex mechanism, which can often fail. If you choose a device responsibly and purchase a high-quality model made of high-strength steel, the product will last a long time and function properly.

Selection principles

To choose a good folding knife, you need to carefully study the assortment. Buy suitable model not difficult, model range devices are very wide. When purchasing, you should pay attention to the following factors:

The material from which the model is made.
Product type.
View of the castle.
Manufacturing company.
Design parameters (it is worth considering the size, for example, if the owner plans to carry the product with him every day, a knife that is too long may not be suitable for him. In this case, it is better to choose a small, compact unit).

The device must be made of durable and very resistant materials, otherwise the device may soon need repairs or even have to be returned. The most best solution for the blade - stainless steel. The handle can be made from real natural wood, metal or durable plastic. In addition to the fact that miscarriages differ greatly in technical parameters, they also have various purposes. There are the following types of products according to the purpose of use:

Tourist.
Tactical.
Military.
Hunting.
Knives for self-defense.

We must not forget that there are certain standards that must be adhered to when choosing a product. A knife whose blade exceeds 90 mm is considered a bladed weapon and carrying it without permission is criminally punishable.

To be fair, it is worth noting that bladed weapons are not for sale in the public domain. Most knives that can be found on store shelves have a special certificate indicating that the product being purchased is not prohibited by law.

It’s not enough just to buy a good one and quality knife, it needs to be carefully looked after. Care includes regular sharpening, cleaning and treatment with special solutions. By observing these simple rules, you can significantly extend the service life of the product.

Offers from European manufacturers

Before you treat yourself to a new acquisition, it’s worth familiarizing yourself with the rating of the best and most popular folding models. These products are different highest quality assembly and long service life.

The top best devices in the world rightfully include:

Products from Russia

Patriots prefer to choose automatic knives Russian production. Unfortunately, there are not so many of them, but choosing a model is quite possible.

You can pay attention to the following devices:

DIY device

Switchblades deserve a separate discussion self made. To collect homemade unit, you don't need to have golden hands. Just look at the simple diagram. The manufacturing process is as follows:

Step 1. Start. First of all, you need to come up with a blade design for your future knife. There is nothing difficult here, there should be 2 grooves on the blade. Thanks to their presence, the blade will be securely held when closed and fixed when open. The desired shape must first be drawn on paper and then carefully cut out.

The resulting template must be applied evenly to the steel and traced along the contour with a marker. For work, it is necessary to choose only steel that contains a sufficient amount of carbon, otherwise it simply cannot be hardened. After tracing, you can start cutting out the blade. To do this, you need to firmly clamp the workpiece in a vice and work well with the grinder. If there is band saw, the process will be much faster.

Next, the blade is processed on a belt sanding machine and give it the perfect shape. After this, you need to grind two grooves. First they are cut out with a grinder, and then finished with a flat file. The main thing is not to forget to drill a hole in the blade, into which the axle will then be placed.

Step 2. Making a lever for fixation. The locking lever must also be made of resistant steel, since this part can be very worn out over long periods of use. The lever is needed to lock the blade in the open and closed position. To make a profile, the profile is placed on metal, marked and cut out. Refinement is done with a file and hand hacksaw. After this you need to make a hole for the axle.

Step 3. Final grinding of the blade. Bevels should be made on the blade. This is an extremely responsible job. It is best to perform this procedure on a tape grinding machine. Everything should be symmetrical. At this stage of the process, you should not sharpen the product too much.

Step 4: Create a handle. You can make a handle out of sheet aluminum and glue a couple more layers to the inside area. One of them will be textolite, and plastic may be useful for the external area. Thanks to these layers, the friction force will be less, and the product will open well.

Using a template, you need to carefully cut out both parts of the handle; in addition, you will need to cut out two more similar parts from PCB. The parts are glued together epoxy glue. When everything is ready, you need to glue them to the final layer. Finally, the parts should be sanded using a grinding machine.

Step 5. Completing the preparation of parts. It is necessary to make a hole in the handle and cut the thread. In addition, it follows small angle bend the locking lever. To do this, you can heat it red-hot with a burner and then bend it. Now you should proceed to installing the spring mechanism. Thanks to the spring, the blade will be thrown out of the handle.

This part is placed on the axis on which the blade is held. Under it in a layer of textolite it is necessary to make seat. First, the holes are drilled and then the work is finished with a sawing machine with an attachment. To secure the spring mechanism, you need to make 2 holes - one in the blade, the other in the handle. All you have to do afterwards is put the handle on. To do this, weld a bolt to the lever, and then cut off the excess parts. It is necessary to make a groove in the handle.

There should also be a spring in the handle that supports the lever. To install it, you need to grind and install a stop. The stop is attached using pins, which can be standard nails.

Step 6. Hardening the steel. Thanks to hardening, the knife will remain sharp for a long time. The hardening temperature for steel is 1071 degrees. The appropriate temperature can be determined externally by the appearance of a yellow glow. In addition, the temperature can be checked with a magnet. It is not magnetic to steel, which means everything was done correctly. The blade needs to be cooled vegetable oil. It also wouldn't hurt to harden the lever. The procedure for heating the metal occurs through a special furnace and burner.

When hardening, you cannot do without tempering the metal; without this, it will not be durable enough. To make a holiday, you will need a very ordinary kitchen oven. It needs to be heated to 200-300 degrees and put the blade there for an hour. After this, you should turn off the oven and leave the blade in it until it cools down. The higher the temperature, the more the metal will sink. Next, you need to check the metal with a file. If not a single trace remains on the surface, then everything went fine.

Step 7. Assembly. Before assembling the parts, you need to polish the blade, since dirt and all sorts of traces of scale will remain on it after hardening. You can polish the blade. At this stage, you can also sharpen the blade, and then seal it with paper and tape to avoid accidental cuts.

After this, it's time to start assembling. You need to install the spring, and then the lever and blade. Steel parts It is best to lubricate them to prevent them from corroding. The product is assembled with screws; grooves must be drilled under their heads to avoid bulging. Next comes the final sanding. First, the handle is worked on a belt sander, and then manually with sandpaper. That's it. The knife is ready.

Modern switchblades are very convenient and practical. Such devices can be used for a variety of purposes. Choosing the right device is not difficult. In addition, you can do it yourself.

Switchblades have a lot of configurations and different principle work. It is quite possible to make such a tool yourself. To do this, you will need to draw up a drawing of the product, for example, simply by tracing the outline of a finished knife. In addition, you will need required material and related equipment, as well as basic work skills.

Preparatory stage

To make an automatic switchblade yourself, you need to take a strip of metal and transfer a sketch of the intended product onto it. Then, using sandpaper or special machine the future blade will need to be processed.

If there is no suitable device, then you shouldn’t even start manufacturing quite complex products. Alternatively, you can use or for finishing. In addition, old ones are sometimes used as points.

After processing the blade and giving it the required shape, the part is clamped into a yew and grinding begins. Initially produced rough finish with a diamond file, then finishing is carried out using a fine-grained stone. The excess metal is sawed off, a hole is drilled in the center in the prepared part, and the end of the product is also sanded.

We continue to make a switchblade with our own hands

At the next stage we will start making the handle. A thin titanium plate is quite suitable for this operation. Using a power tool, cut a rectangular piece the right size. It should be taken into account that titanium is a viscous material; when sawing, it is necessary to lubricate the treated areas with oil.

After preparing a couple of elements, we service them on an emery machine. The ends of the workpieces are brought to the same condition by finishing with a file. Then we place the blade on the handle and clamp it with a clamp. Both halves of the handle are drilled through the central “window” of the tip.

You will also need to make a steel spring, which is processed according to the sketch. The chamfers should be removed from outside holes, fill in the sockets for the button and the locking mechanism. After drilling required holes they are processed with a file to the required size. Bronze or brass bushings can be used as lining clamps. They are placed in the side plates and riveted from the inside.

Assembly

Homemade switchblades at this stage acquire the desired shape and appearance. Elements for riveting are cut from nails or suitable wire. After their installation, it is necessary to grind off the edges to obtain a uniform surface.

Then a rectangular hole is made in the blade using a lathe and an axle is made using a lathe. Alternatively, you can do it with a file, but this process will take much longer. The clamp and the working part are adjusted to each other by cutting out rectangular sockets. A U-shaped fixing element is inserted into the handle of the product.

A spring cut out of steel is secured with a bolt. If the entire procedure is performed correctly, when you press the latch, the spring will act as a pusher. As this element, you can use a similar spare part from a car starter. At the end of the process, the device is polished with a special paste to a mirror shine.

Final part

When making a switchblade with your own hands, you should take care of high-quality linings. They are made of titanium, connected to each other and the blade by grooves and riveting, bringing them to a “marketable” appearance finishing file The blade and axle are inserted, the working spring is charged, the button is mounted, the linings are connected, which are screwed in with bolts. We can assume that the automatic switchblade is ready.

The instructions provided are for informational purposes only. By interpreting it according to the available materials and imagination, any craftsman will be able to make a thing completely different from its analogues, which will rightfully be considered exclusive.

Peculiarities

If you decide to make a switchblade knife with your own hands for the first time, try making a simple sample first. An example would be a product made from a straight razor. Such an instance is created from scrap materials, does not require special qualifications, and has a minimum of details. But finished products will look good on par with store-bought counterparts, having all the necessary functionality.

Before starting work, you need to cut out blade and handle templates from cardboard or plywood. This will allow you to focus on the expected final sample. This is followed by adjusting all the dimensions of the homemade blade. It will fit comfortably in your hand and will be inexpensive in terms of cost. Regardless of what kind of knife you plan to make: a front switch, folding or regular - you can use durable fabric, wood, horn or wood mushroom to decorate the handle.

What to pay attention to

If you decide to make your own switchblade knife, finding a decent material, especially a locking mechanism, can bring certain difficulties. For real masters, this problem fades into the background, but beginners will have to work hard. Alternatively, you can use a similar design from another product that has a working mechanism, but has lost its functionality or relevance.

It will not be particularly difficult to prepare a sketch, design, or cut out the handle. Blade at the right approach can also be turned quite quickly. The main working part in the form of a reliable locking and ejection mechanism may require the lion's share of the time spent on making a homemade cutting tool.

Front ejection switchblades

This type of product has more original principle work. The point is thrown along the handle. Although this option is considered practical and effective, it is more complex design more often leads to breakdowns.

To eliminate this practically only drawback, you need to carefully and reasonably approach the choice of product. In the case of self-production, you should choose practical and reliable components that are designed for a long service life.
