Making a miscarriage knife

Button flick knife, at first glance it is very difficult to do. But in fact, if you carefully understand its device, and have at home necessary equipment and material, then making a throwaway knife on your own does not present any particular problems. As the theater begins with a hanger, so every product (regardless of its complexity) begins with a drawing. Take a sheet 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 from the finished product. Cut out separately from the cardboard the shape of the blade of the future switchblade knife. Attach it with a pin to the sketch of your drawn knife and figure out how its parts will interact. Make all the necessary markup.

Take the one you plan to use and transfer the sketch to it using the blade template. Now you can start processing the blade on the emery. I would like to say that now for home use, you can buy any equipment. Starting from an emery machine and ending with a mini-lathe. If you don’t have at least emery, then you shouldn’t even start making such a not-too-simple product, like a switchblade knife. However, the most stubborn ones can use: a hand drill, a home-made whetstone on a motor from a fan, a file, a hacksaw for metal and a set of needle files. It's longer, but not worse. You can also use for blades, old kitchen knives.

After you have processed on the emery, giving it the necessary shape and sharpening, hold it in a vise and start grinding it. First, we do roughing with a diamond file, then finishing with a small block. Saw off the excess piece of steel strip from your blade and drill a center hole on it with a drill press. Sand the edge of the blade on an emery machine.

Now let's get down to making the handle of the switchblade knife. Thin titanium is fine. We cut off the electric with a jigsaw for metal a rectangular strip of the required size. Since titanium is a viscous metal, lubricate the place where the cut is made with oil. We make two such rectangles. We make preliminary marking on one of them, and clamp both pieces into clamps. We are again waiting for exciting work on an emery machine. We then process the ends of the blanks of the switchblade handle with a file to give both halves a complete identity.We put 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 the necessary holes on it according to the sketch. Now, having attached the spring to the handle of the switchblade, we drill holes. Don't forget to chamfer the outside of the holes. Kern on the handle holes for the button and the spring retainer. Now we drill them with a thin drill. We process the file to the required size. Bronze bushings can be used to fasten the linings. We insert them into the side plates and rivet from the inside.

Now you can assemble our entire design flick. We cut pieces for rivets from wire or nails. We rivet. We grind the rivets with a file to obtain a uniform surface.

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

We adjust the blade under the latch by sawing out rectangular grooves. We make a p-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 tape. Secure the retainer spring with the bolt. Now pressing the latch, you will feel that the spring tends to push it back. The blade ejector spring can be used from a car starter. We grind the blade to Goy's paste.

Next, we make overlays. What material to use for knife handle linings we talked about. We cut out two rectangular strips of overlays. Drill holes in them. Put on the handle and give shape to the emery. Let's finish with a file. We have all the details, you can start assembling the switchblade knife. We insert the blade, the axis, cock the throwaway spring, insert the button, connect the lining, screw them with bolts. The switchblade is ready.

Of course, the given photos and mine short description not even enough to complete the work on the manufacture of a switchblade knife. 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 switchblade button knife. All photos are taken from this video. Please consider this article for informational purposes only.

Manufacturing should begin directly with the blade. First of all, we mark the place for the axial hole. We drill it and, already guided by it, we make further marking of the blade. If you do the opposite and mark and cut the blade along the contour, and only then drill a hole, then during the drilling process, especially in hardened workpieces, the drill can lead to the side and all dimensions will “float away”.

Transferring the contours of the blade to the workpiece, we begin to make the blade. We grind with the help of a grinder and emery along the contour. For the convenience of holding the blade in the process of removing the descents, the blade itself is not cut off from the workpiece yet and the heel of the blade is not formed.

Various tools can be used to remove slopes: grinders, emery, flat grinders, grinders. I do a rough turning of the slopes on emery and a fine one on a flat grinder.

Next, we proceed to the manufacture of side dies.

Next, we drill a hole in the dies for the pin of the blade stopper, install the axis and stopper pin, install the blade and the second die. Move the blade to open position and mark on the die the position of the heel of the blade, or rather the place where the lock liner should rest. Next, mark the liner and proceed to cut it.

Having prepared the ribs in this way, we proceed to their installation on the dies. The methods are different: soldering, riveting, spot welding, etc. The most accessible are soldering and riveting.

For soldering, you will need a soldering iron, soldering acid, solder and a heat source. As a soldering iron, it is best to use a massive piece of copper, which is heated in a burner flame. Soldering acid is hydrochloric acid etched with zinc. POS-60, POS-90 are suitable as solder. Before soldering, it is necessary to clean and tin the soldering points. It is cleaned with sandpaper, a file. After stripping, we coat the soldering points with acid, take, on a well-heated soldering iron, a piece of solder and tin the surface. In the process of tinning, it is necessary to ensure that there are no gaps left and that the entire surface is covered with an even layer of solder. High-quality tinning and soldering are possible only with good heating of the parts.

After tinning, rinse the parts well in water with soda, removing acid residues. Next, we clamp the tinned parts in a vise and begin to warm up with a burner from different sides. To reduce heat loss under the vise jaws, it is necessary to lay a thermally insulating material; fragments of ceramic tiles are well suited. As it warms up, we tighten the vise until droplets of solder come out between the parts, after which the heating can be stopped.

The soldering of the right fitting has some peculiarities: first, we solder the axis of the knife into the die, and then solder the fitting, while instead of one of ceramic tiles use a piece of tube larger than the diameter axis.

So, all the components of the knife are ready, it remains to assemble the knife, once again make sure that the lock is working correctly. Adjust if necessary. For smoother operation of the mechanism, it should be lubricated with engine oil. After some time of operation, the parts of the mechanism should be rubbed in, the blade will rotate easily and smoothly, the liner plate will rise slightly.

Want to make your own switchblade? Then take a look at this guide. Such a knife will be very useful in your pocket, especially if you go hiking or just walking in nature. Who knows who you will meet along the way? Also, with a knife, you can always cut something, cut it, tuck it in, or even unscrew some screws if necessary. In this tutorial, we will look at how to make just such a knife.

The author used N690 steel as the material for the manufacture of the blade. It is well suited for the manufacture of knives, it is easily hardened and knives from it perfectly keep sharpening. The knife is not difficult to assemble, but the author uses a belt grinder, which greatly simplifies this process.

Materials and tools used

List of materials:
- ;
- spring;
- bolt;
- aluminum foliage for the manufacture of 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 nozzles;
- wrenches, pliers, etc.

Knife making process:

Step one. Let's start with blade making
First of all, you need to design the blade for the 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 circle it with a marker. Blade steel must have a large amount of carbon, otherwise you will not be able to harden it. Now you can start cutting the blade. To do this, we clamp the workpiece in a vice and work as a grinder, and if there is band-saw, then it is all done much faster.

Now we process the blade on a belt grinder, bring the profile to the ideal.
At the end, you will need to carve grooves in the blade, this design provides for two pieces. First, we cut them out with a grinder, and then we refine them with a flat file.

Do not forget to also drill a hole in the blade into which the axle will be installed.

Step two. We make a locking lever
The locking lever must also be made of durable steel, since the holding hook may wear out during prolonged use. The lever locks the blade in two positions, first closed and then open.

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

Step three. Final polishing of the blade
Bevels need to be formed on the blade, this event is very responsible. You can quickly and efficiently do this on a tape grinding machine. The main parameter here is symmetry. Do not sharpen the knife too much at this stage, as the blade can lead when hardened, and thin metal can overheat greatly.

Step four. We make a pen
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, 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, you will also need to cut out two similar parts from the textolite. Glue the pieces together using epoxy glue. When the parts are ready, glue them with epoxy to the final layer. When the glue dries, cut them out.

Finally, sand the parts on a belt sander.

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

Let's install the spring. Thanks to it, the blade will automatically extend from the handle. The spring is mounted on the same axis as the blade is held. Under it in the textolite you need to cut out a seat. First, the author cuts it out by drilling a series of holes, and then reams it with a drilling machine and a special nozzle. To attach the spring, you need to drill two holes. We drill one in the handle, and the other in the blade.

All that remains for you to do is to 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 extra parts. Under the "handle" in the handle, you need to make a groove with a round file.

The handle also has another spring that supports the lever. For this spring, you will need to grind and install the stop. We fix the stop using pins. Ordinary nails can act as pins.

Step six. Steel hardening
We start hardening, thanks to this the knife will not be dull for a long time. For N690 steel, the quenching temperature is 1071 degrees Celsius. Visually, this temperature is determined by the yellow glow. You can also determine the desired temperature with a magnet, if it is not attracted to hot steel, then it is heated to the desired 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 burner and a special stove.

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

A folding knife is a great tool in a man's pocket and not only. You should definitely take it with you, going on a hike or just to nature. With a knife, you can not only cut sausage or open beer, but also protect yourself from enemies. And more often the enemy is not a person, but an animal, for example, a dog or even a fox. In this tutorial, we will look at how to make a good simple DIY folding knife.

To make a knife, the author used a rather professional set of tools, he needed a jigsaw and other tools. But you should not despair, if you have skillful hands, such a knife can easily be made ordinary hand tools. The fixing device of the knife is also simple, all parts are made by hand. So let's get started.

Materials and tools used

List of materials:
- high carbon steel (which can be hardened);
- pins (you can steel or brass);
- material for overlays (wood, plastic and so on at will);
- epoxy adhesive;
- spring rod (for making a spring).

List of tools:
- ;
- drilling machine or drill;
- clamps;
- Bulgarian;
- vice;
- paper, pencil, scissors for making a template;
- sandpaper;
- furnace, oil for hardening.

Knife making process:

Step one. Sample
First of all, the author makes a template, including all internal details. For those who have already made a knife at least once, it will not be difficult to make such a template. You need to think over the locking mechanism, it is made in the form of a lever with a hook.

Step two. Cut out blanks
The author cuts all the details of the knife from sheet steel. The locking mechanism consists of two parts, one part holds the spring, and the second is a lever with a hook that holds the blade.

To make a handle, you will need to carve two identical parts. All details, including the blade, are cut out by the author using a grinder. IN hard-to-reach places, where the grinder cannot crawl, we make a lot of transverse cuts, and then gradually cut them out.

For the manufacture of the blade, you will need steel with a high carbon content, in America it is customary to use steel 1050, in Russia steel 65X13 can be considered the most common grade of steel for making knives. Good steel, which can be hardened, is widely used in the manufacture of tools. You can also use steel from an old cutting disc.

When you cut out the blanks for making the handle, assemble them on pins or simply on bolts. Now sand the product along the contour, as a result you will get two identical parts.

Step three. Grinding
We proceed to finer processing of blanks, namely, grinding. This is where a belt sander comes in handy. We bring the details to the ideal, and in the end we go through manually with a file where we could not get close to the machine.

Using a grinder, you also need to remove the bevels on the blade. The author attaches the blade to a special fixture and gets to work. The main criterion here is the symmetry of the bevels.

At the end, the author processes the details manually using sandpaper. The next step for us will be hardening, before that, do not forget to drill all the necessary holes in the workpieces, since then it will be problematic to do this.

Step four. Tempering the blade
In order for your knife to keep sharpening for a long time, the blade must be hardened. Since we have a blade small size, it can be easily heated to the desired temperature with a burner, as the author did. Calim the metal until the steel is no longer attracted by the magnet. If we approach this matter more professionally, then for each steel there is a clear heating temperature.

When the steel is hot, dip the workpiece into the oil. Waste oil from a car, as well as vegetable oil, is quite suitable. After cooling the workpiece, go through the metal with a torch to burn the oil. Now the steel can be checked, if it is not taken with a file, then the hardening was successful.

The next step in hardening is necessarily metal tempering, otherwise the steel will be very brittle. For holidays, a household stove is suitable. Place the blade in it and heat it for about an hour at a temperature of 200-250 degrees Celsius. Then let the oven cool down with the knife inside. Vacation done! Now the steel will spring, and the blade will not break under high load.

Step five. We proceed to the assembly of the knife
After hardening, polish the blade to a shine, as after heat treatment it will change color. Now the knife can be collected. Lubricate all internal parts with engine oil so that the knife does not rust from the inside. Now we collect everything on the pins. Glue the pads with epoxy glue.

Clamp the handle well with a few clamps and let the glue dry completely. Epoxy usually takes about a day to dry.

When the glue is completely dry, we make the final polishing. First, the product is processed on a grinder, and then manually, using sandpaper. At the end, we bring the handle to perfect smoothness with fine sandpaper.

Knives are currently popular not only in the kitchen, but also among people who have connected their lives with extreme outdoor activities - these are: fishing, hunting, tourism, etc.

In modern times, there are various knives on the market: variable models, different sizes and designs. But none of them can replace a knife that is made by hand.

How to make a knife with your own hands is often written on the Internet, and you should try to make them.

Knives: types and main properties

On the photos 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, a 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 for tourism can be easily made at home on your own.

There are also such knives as survival knives, the main task of which is to help with existence in the wild. 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. The small dimensions make it easy to transport such a knife.

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

Steps to create a knife

To get a positive result during the manufacture of the knife, you must first sketch out the 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 includes a number of rules.

Making a knife step by step

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

You will need a knife sharpener. With its help, bring the base to the desired shape. And after that, an already understandable blank will be in the hands, where you can distinguish the places of the handle and blade.

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

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

Do not expect perfect sharpening from this stage, because this is just a draft, intended to determine the future shape.

If the blade is pre-prepared, then you can start working with the handle. The handle is made using the most various materials- these are: wood, organic glass, bones, thick types of leather, etc.

Note!

Having cut out the workpiece to create the handle, you should check whether it fits comfortably in your hand, as well as its proportionality with respect to the blade. The handle for the knife is fixed using the riveting method.

The shape for the foot handle is attached using a grinding machine.

The knife is ground and polished on the basis of sandpaper.

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

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

Note!

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 set the necessary and desired design for the future knife. Pay special attention to the handle during the design process.

knife design

Since it is by the handle of the knife that the rest 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 an emergency in the forest, the main thing is to find the materials necessary to create it.

Note!

It is worth finding only 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, ropes or leather.
