Good evening Gentlemen and Ladies, thrill-seekers!

Could someone please email me the drawings of a switchblade (or better yet, several to choose from). It is advisable that the blade be thrown straight out and the one to the side. I’ve been trying to find it on the Internet for a week now, it’s useless(((You are my last hope)
my email: [email protected]

Thanks in advance, with uv. Vadim

But Zarathustra doesn’t allow you to buy 2 Chinese miscarriages at the market and make a drawing?

ostrij 31-08-2011 23:07

Why is it difficult to send a drawing?

And if it’s not freely available, it means it’s not there at all or they just don’t want to share it...
Therefore, I would do as the Sergeant advises. At the same time you will understand what's what.

Basil_84 31-08-2011 23:51

What, so? Is it prohibited by law?

We need to at least look at the Beltrame miscarriage. The spring and lock are not similar to those on the Chinese.

Basil_84 31-08-2011 23:58


And what for then.... Although it’s up to you.

Here is the simplest, IMHO, option:

Miscarriage with lateral discharge (like most chum salmon).
The frontal ejection will be too difficult for the first time. And for the second one too ;-)
I personally have never seen the drawings at all. However, for a single production “on the knee” they are not particularly needed: a sketch with approximate dimensions is enough, the parts are still fitted in place.

Usually I try to help people, but in the case when a person does not respect others (or is afraid) so much that he refuses to even name his country of residence (Europe is not a country), I am forced to refuse help

ostrij 01-09-2011 19:04

Thanks to those who sent photos!!!
I would like to detailed drawing take a look (especially the one with frontal ejection), since I want to make a knife not on the knee, but on machines.

suhai123 01-09-2011 20:53

dialectical contradiction. Prohibited by law but on machines

ostrij 01-09-2011 21:06

Well, no one knows what I’m doing there))) detail by detail...)

Zuzamod 01-09-2011 21:38

Well, write a request to the manufacturers, for example http://www.microtechknives.com/index.html There is a 0.0001% chance that they will answer and not just send.

no one owes anyone anything here. It was a request on my part. whoever wants to help. But making a secret out of a Wikispirit drawing is not entirely smart, because it’s not nuclear rocket in the end) Santjago 03-09-2011 22:01

I haven’t come across drawings in the open spaces yet either... If you have the desire and a little skill, you can make one from a photo. The main thing is that there is desire. So don’t really expect that everything will be laid out for you on a silver platter, with tolerances and fits.





Want to make your own switchblade? Then take a closer look at these instructions. Such a knife will be very useful in your pocket, especially if you go hiking or just walk in nature. You never know who you will meet along the way? Also, with a knife you can always cut something, cut it, pick it up, or even unscrew some screws if necessary. In this instruction we will look at how to make just such a knife.

The author used N690 steel as the material for making the blade. It is well suited for making knives, it is easily hardened and knives made from it hold an edge well. Assembling the knife is not difficult, but the author uses a belt sander, which greatly simplifies this process.

Materials and tools used

List of materials:
- ;
- spring;
- bolt;
- aluminum foliage for making handles;
- textolite or something similar (used to finish the internal parts of the handle);
- epoxy adhesive;
- pins (nails will do);
- screws.

List of tools:
- ;
- vice;
- drilling machine;
- ;
- Bulgarian;
- files;
- marker;
- “Dremel” with grinding and polishing attachments;
- keys, pliers, etc.

Knife making process:

Step one. Let's start with making the blade
The first thing you need to do is develop a blade design for your knife. There is nothing complicated about this; the blade should have two grooves, thanks to which the blade will be held closed, as well as open. First draw the desired profile on paper and then cut it out.


We apply the finished template to the steel and trace it with a marker. The steel for the blade must have a large number of carbon, otherwise you will not be able to harden it. Now you can start cutting out the blade. To do this, we clamp the workpiece in a vice and work with a grinder, and if there is band-saw, then this is all done much faster.
















Now we process the blade on a belt grinding machine, we bring the profile to the ideal.
Finally, you will need to carve grooves in the blade; this design provides two pieces. First we cut them out using a grinder, and then we finish them using a flat file.

Don't forget to also drill a hole in the blade into which the axle will be installed.

Step two. Making a locking lever
The locking lever must also be made of durable steel, since when long-term operation The retaining hook may wear out. The lever fixes the blade in two positions, first in closed and then in open state.

We apply the profile to the metal and cut it out, finishing it with files and a hand saw. Finally, drill a hole for the axle.














Step three. Final grinding of the blade
You need to form bevels on the blade; this is a very important undertaking. This can be done quickly and efficiently using a belt machine. grinding machine. Main parameter here is symmetry. Do not sharpen the knife too much at this stage, as the blade may lead during hardening, and the thin metal may overheat.











Step four. Making a handle
The author makes the handle from sheet aluminum, gluing two more layers to the inside. One of the layers is textolite, and the second, outer one, is probably plastic or something similar. Thanks to this layer, friction is reduced and the knife opens perfectly.























Using the template, cut out two parts of the handle, and you will also need to cut out two similar parts from PCB. Glue the parts together using epoxy glue. When the parts are ready, glue them with epoxy glue to the final layer. Once the glue has dried, cut them out.

Finally, sand the parts using a belt sander.

Step five. Final preparation of all parts
You need to drill holes and tap threads in the handle; it will be assembled with screws. You also need to bend the holding lever at a certain angle; to do this, the author heats it red-hot with a burner and then bends it.




Let's start installing the spring. Thanks to it, the blade will automatically extend from the handle. The spring is installed on the same axis that holds the blade. Under it you need to cut out in the PCB seat. First, the author cuts it out by drilling a series of holes, and then drills it out using a drilling machine and a special attachment. To attach the spring you need to drill two holes. We drill one in the handle, and the other in the blade.


















All you have to do is install the “handle” with which you will activate the knife. To do this, we weld a bolt to the lever, and then cut off the excess parts. Under the “handle” in the handle you need to make a groove using a round file.










The handle also has another spring that supports the lever. For this spring you will need to machine and install a stop. We fasten the stop using pins. Ordinary nails can serve as pins.

Step six. Steel hardening
Let's start hardening, thanks to this the knife will not become dull for a long time. For N690 steel, the hardening temperature is 1071 degrees Celsius. Visually, this temperature is determined by a yellow glow. More desired temperature can be determined by a magnet; if it is not attracted to the hot steel, it means that it has been heated to the required temperature. Cool the blade in mineral or vegetable oil. As for the lever, it is also highly desirable to harden it. The author heats the metal using a torch and a special stove.






An integral part of hardening is the tempering of the metal; without this procedure, the metal will be very brittle. To bake, you will need a regular household oven. We heat it to a temperature of 200-300 degrees Celsius and heat the blade for an hour. Then turn off the oven and let it cool closed. The higher the tempering temperature, the more you temper the metal.
Finally, check the steel with a file; if it does not leave scratches on it, then the hardening was a success.

IN 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 progenitors of the model were invented back 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, the modern automatic knife 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 models of automatic folding knives are brought into a ready state thanks to a special button. When you press it, the spring mechanism is affected, causing the blade to be 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. 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 approach the choice of device with all responsibility and purchase 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, the lineup 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 The best decision for the blade - stainless steel. The handle can be made of real natural wood, metal or durable plastic. In addition to the fact that miscarriages vary greatly in technical parameters, they also have different 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 to just buy a good, high-quality knife; you need to take care of it carefully. 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 for a long time services.

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 hold securely in closed and be locked in the open position. 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, you need to choose only steel that contains sufficient quantity 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 you have a 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 belt sander. 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 the 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 with 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. It is necessary to make a seat under it in the textolite layer. The holes are drilled first and then the work is completed. sawing machine with nozzle. 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 secured 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 does not magnetize to steel, which means everything was done correctly. The blade needs to be cooled in 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 take a vacation, you will need the most ordinary kitchen oven. It needs to be heated to 200-300 degrees and put the blade there for an hour. After this, 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 well.

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 that, it's time to start assembling. You need to install the spring, and then the lever and blade. It is best to lubricate steel parts 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 grinding machine. tape machine, and then manually using sandpaper. That's all. 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.

Making a knife miscarriage

A push-button switchblade, at first glance, is very difficult to make. But in fact, if you carefully understand its structure and have it at home necessary equipment and material, then making a blowout knife yourself does not present any particular problems. Just as a theater begins with a hanger, so every product (regardless of its complexity) begins with a drawing. Take a piece of paper or cardboard and draw a knife on it. If your talent as an artist is still deeply buried, then simply trace the outline of the knife with finished product. Separately cut out the shape of the blade of the future switchblade from cardboard. Attach it with a pin to the sketch of your drawn knife and figure out how its components will interact. Make all the necessary markings.

Take the one you plan to use and transfer the design onto it using the blade template. Now you can start sanding the blade. I would like to say that now you can buy any equipment for home use. Starting from an emery machine and ending with a mini lathe. If you don’t have at least some sandpaper, then you shouldn’t start making something as simple as a switchblade. However, the most stubborn ones can use: hand drill, a homemade sharpener on a fan motor, a file, a hacksaw for metal and a set of needle files. It's longer, but no worse. You can also use old kitchen knives for the blade.

After you have sanded it to the desired shape and sharpness, clamp it in a vice and start sanding it. First, we do rough processing with a diamond file, then finishing with a small block. Saw off the excess steel strip from your blade and drill a center hole on it drilling machine. Sand the end of the blade using an emery machine.

Now let's start making the handle of the switchblade. Thin titanium will do just fine. Using a metal jigsaw, we cut a rectangular strip of the required size. Since titanium is a viscous metal, lubricate the area where you are cutting with oil. We make two such rectangles. We make preliminary markings on one of them, and clamp both pieces into clamps. Exciting work on the sanding machine awaits us again. We then process the ends of the switchblade handle blanks with a file to give both halves complete identity.Place the blade on the handle blank and clamp it with a clamp. We drill both halves of the handle along the central hole of the blade.

We cut out another part from a steel strip, called a spring. We process it and saw through it according to the sketch required holes. Now, attaching the spring to the switchblade handle, drill holes. Don't forget to chamfer the outside of the holes. We punch holes on the handle for the button and spring retainer. Now we drill them out with a thin drill. We process the needle file until required sizes. Bronze bushings can be used to secure the linings. We insert them into the side plates and rivet them from the inside.

Now we can assemble our entire valve design. We cut pieces of wire or nails for riveting. Let's rivet. We grind the rivets with a file to obtain a uniform surface.

We cut a rectangular hole in the blade with a diamond needle file. Now with the help lathe let's make an axis. If desired, you can do without a lathe by using files.

We adjust the blade to the latch by cutting out rectangular grooves. We make a U-shaped clamp. We insert the latch into the handle of the miscarriage knife. Now we need a spring for the latch. You can cut it out of steel strip. Secure the retaining spring with a bolt. Now when you press the latch, you will feel that the spring is trying to push it back. The blade ejector spring can be used from a car starter. Grind the blade with Goya paste.

Next we make the overlays. We discussed what material to use for knife handle linings in. Let's cut out two rectangular strips of lining. Let's drill grooves in them. Place it on the handle and shape it using sandpaper. Let's finish it with a file. We have all the parts, you can start assembling the switchblade. We insert the blade, the axle, cock the release spring, insert the button, connect the linings, screw them in with bolts. The switchblade is ready.

Of course, the above photographs and mine brief description It’s not even enough to complete the work of making a switchblade. Therefore, I provide a link to the video on YouTube, http://youtube.downloader.com.ru/KiD2Cf8ammA where the master describes in great detail and step by step how he makes this push-button switchblade. All photos are taken from this video. Consider this article just for informational purposes.

We present to your attention a full-fledged video lesson on how to make your own push-button switchblade. Most will not be used here simple materials, like plastic and so on, but they also cannot be called difficult to access. As a result, you will get a real professional switchblade that can be used in different conditions and with different materials.

Many modern knives are no different good quality and practicality. They are inconvenient to use, uncomfortable to hold in your hand, and so on. It is for this reason that we suggest making your own, so that it can serve you well and be practical in all respects.

The video lesson focuses on the following points:

  • the handle of the knife should be in the palm of your hand (so that it fits comfortably in your hand, and not in two fingers);
  • the blade is sharpened on one side (on the right - if right-handed, and vice versa);
  • If possible, make notches on the base of the blade.

The entire manufacturing process is divided into several stages. First of all, a sketch of the future knife is made. This is necessary in order to understand how all its components interact with each other. Then, we begin to prepare the details. We transfer the sketch of the blade to the steel and process it. The original form may change during the process. Immediately sharpen the blade on one side.

After this, we grind the blade. We make a hole at its base. We process the edges according to the shape of the sketch.

Let's start creating the handle. Take a piece of titanium and measure according to the sketch right size and cut out a shape from it. Glue the two resulting halves together and clamp them in clamps. Using the marks made, we make indentations.

We adjust the handle to the blade. We make a hole in the handle at the same distance as the blade. After this, we cut out another part for the design of the knife.

We connect everything together and make several holes in all parts except the blade. We insert bronze bushings into two of them to secure the linings.

Using nail rivets, we connect all three resulting parts together and hammer them in with a hammer.

We make an axis for the knife using a lathe, a diamond file and other tools. You will learn more about this in the video lesson.

We make a clamp from an unnecessary flat nut. We drill a hole in it and thread a wire so that we can conveniently harden the element. Quench over high heat.

We process the retainer and insert it into the structure. Now, you need to cut out the spring for the retainer. We connect the elements and secure them. We take a spring from a car starter and attach it in the same way. The result is the following design.

Before covering the handle with covers, you can make serrations at the base of the blade in the previous step. For the overlays we take vinyl plastic with a thickness of 5 mm. We cut out two parts measured according to the sketch. We drill several incomplete holes in them. We adjust the parts to the shape of the knife, connect them together and process them.
