DIY kitchen knife at home. How to make a kitchen knife with your own hands at home. A kitchen knife is the main tool of a professional chef. It must be strong, sharp and reliable. Real, branded chef's knives are quite expensive, their cost can start from $200 to $3000 or more. We will try to make a high quality knife, investing only $ 10, and common hand tools will be used for work.
Making each such knife requires a lot of effort, so you will need a lot of patience. The author, working with hand tools, spends about 20 hours on each knife.
Of course, no one forbids the use of power tools, so the work process will be faster and easier.
Materials and tools.
List of materials:
- billet of high-carbon steel (such steel can be hardened);
- a wooden block or boards (for making a handle);
- brass rods (or ordinary nails for making pins).
- a hammer;
- hacksaw for metal;
- files for wood and metal;
- marker, paper;
- epoxy adhesive;
- pliers;
- gloves;
- sandpaper;
- wood impregnation oil.
Step one. Choosing the right steel
Only one thing affects the quality of a knife - the steel used. In order for the blade not to dull for a long time, and the blade to be as thin as possible and cut everything like a blade, the steel must have a high carbon content. The more it is, the stronger the steel will become. Due to the large amount of carbon, steel can be hardened, it is carbon that gives rigidity to the metal during hardening.
Such steel is usually used in tools, these are files, wrenches and more. It is also commonly used in springs, for example, you can use an old car spring. The author used steel 01 for such purposes, as well as 1084. Steel 1095 also gained quite wide popularity. In principle, you can always buy a finished workpiece from the desired steel.
Step two. Cut out a rough profile
First of all, decide on the shape of the knife. You can take a finished profile from already made knives. You can change the existing profile to your taste. We draw it on the workpiece, and then cut it out with a hacksaw for metal, holding it in a vise. If there is a grinder, great, you can cut the profile with it.
There is one more nuance here, if your workpiece is hardened, then it will not be possible to cut it with a hacksaw. To work with hand tools, you will need to release the metal. Heat it to red, for example, in good coals, and then let it cool in the open air. After that, the metal should become soft. If this does not happen, then the steel was poorly heated.
In order not to damage the workpiece with the steel lips of the vise, clamp it between two planks or blocks.
Step three. We form bevels
Bevels - this is the angle of sharpening, the wider the bevel, the smoother and thinner the blade will be, as a result, the knife will cut better. First, mark the bevel lines on the blade on both sides, and then draw a central line along the blade, as the author did. To draw the center line, you will need a drill with the same diameter as the thickness of the blade.
Now we take a file and evenly remove the metal. This is not done quickly with a file, but you have practically no chance of spoiling the workpiece, when compared with a grinder. Sew one end first, then the other. After a coarse-grained file, at the end of the work, take a fine one to remove deep scratches.
Step four. Blade surface grinding
Now you can start grinding the workpiece. The task will be to make the surface absolutely smooth and even, to remove various defects after rough processing. First we use coarse sandpaper, and then finer and finer. At the end, the paper grain should be 1200 units. If desired, after grinding, you can polish the metal, but for now it is pointless to do this, since hardening is still waiting for us, after which the metal will have to be polished again.
The handle is fastened with two pins, the author uses rivets as them, they are large and look spectacular. We drill holes of the required diameter for the selected pins. At a minimum, you will need to make two holes, the rest are optional. Drill carefully, to be sure, clamp the workpiece in a vise. The steel is quite thick, so you can easily break the drill.
Steel needs to be hardened, so it will become hard, and the knife will keep its sharpness for a long time. For these purposes, you can assemble a simple oven powered by a gas burner. In the simplest case, we take coals, blow them up with a household hair dryer or other source of air supply. Steel must be heated to a bright red color, however, each type of steel has its own color indication. To check the desired temperature, find a permanent magnet. If the steel is properly heated, the permanent magnet will not be attracted to it. The workpiece must be evenly heated along its entire length.
Next, we cool the metal in oil, it is preferable to use vegetable oil. A motor one is also suitable, but it is not recommended to use mining, as it contains a lot of contaminants, which can damage the top layer of metal.
When the metal has completely cooled, handle it very carefully, as the steel is now very brittle. Metal release will allow the knife to be elastic. Thanks to this procedure, we soften the steel a little, and it acquires spring properties. For this procedure, you will need an oven, it is important for you to know the temperature, it should be in the range of 200-230 ° C. We place the workpiece in the oven for an hour and a half, and let it cool together with the oven, do not open the door. Everything, after that you will receive a workpiece of excellent quality.
Step seven. Sharpening and polishing
After quenching, the steel will have a lot of impurities, such as scale, burnt oil, and so on. This whole thing has to be cleaned up. We take fine sandpaper, moisten it in WD-40 or ordinary water and grind the surface. When you clean the metal, you can polish it. You can use GOI paste and other substances.
After polishing, sharpen the blade. This can be done with very fine sandpaper, you can use whetstones, and Japanese water stone is best, it comes in different grits. Moisten the grinding stone with water, this allows it to self-clean and it sharpens metal well. A quality knife should cut paper without difficulty.
Step eight. Pen
Before you finish the handle with wood, cover the blade with masking tape, tape it, or secure it in some other way so as not to cut yourself. The pads on the handle are made of wooden boards or a bar, which is sawn into two halves. We cut the blanks to the desired size, drill holes and then assemble them on pins. After making sure that everything is assembled correctly, glue the blanks with epoxy glue and clamp the handle with a clamp until it dries completely.
When the glue dries, we take a file on a tree and form a handle profile, this is not difficult. It is easier to carry out such work on a grinder with a coarse-grained stone. Well, then we take sandpaper and make the handle absolutely smooth. You can polish it if you wish.
At the end, we use impregnations for wood, otherwise it will instantly crack from water. Linseed oil will come to the rescue. Oil can be mixed with beeswax by heating them in a water bath. The resulting "ointment" is applied to the tree and allowed to soak. Finally, polish the surface.
As a result, we have an excellent kitchen knife that you can envy!
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, 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. A variety of materials are used to create the handle - 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.

MANUFACTURE OF KITCHEN KNIVES
Having redone a lot of any cold, piercing - cutting, I suddenly noticed that in the kitchen there is no sensiblekitchen knife. Well then, let's start making it. First, let's decide on the workpiece: you can take steel 65G or 95X18. I do not consider other options, due to their lower quality and low prevalence. If there are problems with workpieces and subsequent hardening, you can simplify the process by using a piece of a saw blade or other metal-cutting tool for the knife.On the emery wheel, we give the iron the desired shape. Pre-scratch the contour of the knife according to the template. I use fiberglass templates for this.
After removing excess metal, we bring shine with a circle with sandpaper.
Having drilled two or three holes with a diameter of 3 mm for fastening, we get this:
Now it's time for the handle. Someone uses plastic for these purposes, some are caprolon, some are plexiglass, some are metal. But the best results are obtained from a simple tree - and durable, and comfortable, and pleasant to hold. For the preparation, a wooden leg is taken from the chair.Cut in half with a hacksaw
These two halves will be the handle of the knife. Fastening is done on rivets made of aluminum wire.
Having firmly attached them to the iron, we drill mounting holes and put them on M3 screws for further processing.
To give a preliminary shape to the handle, we use an abrasive grinding wheel.
Already something like a knife. Now you can replace the screws with rivets.We finally shape the handle with a rasp and polish it with a strip of sandpaper, first coarse-grained, and then finer.
Knife can be made from anything
Today, I would like to continue the topic of affordable material, from which you can quickly and easily with good characteristics. Many are interested in the question of what is possible without resorting to complex technologies. This is covered in some detail in . Here we will try to further highlight some of the details of a suitable material for knives. The easiest way is to use old broken stainless steel kitchen knives. Knives should preferably be Soviet-made, not Chinese consumer goods. From such a fragment you can make a good knife with excellent cutting characteristics.
Also, good knives can be made from high speed steel, which is used in the manufacture of hacksaw blades for power saws. The disadvantage of this material is that it is quite fragile and tends to rust. But it keeps a good edge.
An excellent material are knives for a wood planer. This metal is very well processed and polished. The planer knife is burnt red-hot with a blowtorch and then cooled. After annealing, the metal can be safely sawn with a hacksaw, shaped, sharpened with a file. After the knife is given its final shape, it needs to be either in oil or in water. But, unfortunately, knives made of this metal also rust.
The next metal that we will consider is a regular file. It is very easy to make a knife from a file, without any special machines. Take a file, heat it well again with a blowtorch red-hot and let it cool. After that, it is very well processed with another file, sawn with a hacksaw to give the desire the desired shape. Further, quenching is again carried out in oil or water. The main thing in order to get a good knife from this metal is needed. There is no need to forge this metal. We simply burn, sharpen, file, remove excess metal with a hand tool or sandpaper. And we get a pretty good knife.
It can also be made from an ordinary hacksaw for wood. It is also very easy to process, very elastic steel. It can be adapted, for example, to make a kitchen knife that will cut well and keep sharpening well.
An automobile spring is also well suited for manufacturing. The only thing bad about a spring is that it needs to be forged and properly heat treated. This is a rather labor intensive task. But if you build a homemade forge in your area, then you can make a good knife from a piece of spring. Or just take it to the blacksmith, who, for a bubble of vodka, will forge anything for you.You can make a knife from a car valve. It also makes good stainless steel. The valve is heated to a strong temperature, forged on an anvil. Then you need to shape the blade and harden it.
Very good knives are made from large drills. Clamp the drill in a vise, heat it to a soft state, take the gas wrenches and begin to slowly unwind it. After that, heat up again and begin to forge the resulting part, giving the desired shape. The drill is sharpened with a file, it will not. All work on must be done on sandpaper.
The knife can be made from spring steel. It is not necessary to anneal this metal. Immediately from the workpiece, you can make a knife blade. This steel is not drilled with a conventional drill. You must use a drill bit.
Now let's talk about rust, which is present in most metals. If you want to keep your knife from rusting, you can treat it with sulfuric acid or phosphoric acid.
The material used in the article is from a YouTube video.
We all want to have a good kitchen knife in the kitchen, if only because our wife, our most beloved person, works with it.
How many of them are on the market, you can’t count them and the firms are different, and the style and materials and shape, what to choose, your eyes run wide. Pricing policy also varies greatly from very democratic prices to simply cosmic ones. Below are knives from 200 to 25,000 rubles.
Usually you take a knife in your hand and think: the handle is made of beautiful pieces of wood, the blade shines like a mirror, and at the same time, “everything is wrong, guys…”. I wanted to assemble it into a knot.
All ideas are aimed at two qualities that I see as the main ones in the kitchen: cutting and wear resistance, and the purpose of the knife is supposed to be universal - cutting vegetables, gastronomy, bread.
The first consideration is about what most affects the cut - convergence (bevels at the knife from the butt, not the working part of the knife to the tip). You don’t need a convergence of more than 0.2 in the kitchen for vegetables and bread. If the owner's hands are clumsy, we will do 0.25-0.3. All the other dozens on carts are bricks tied to a bicycle. If you really spend your time and consumables on making a knife, then is it worth making it identical to Tramontina?
In my opinion - no. It should be done much better! In Tramontin, the upper series have convergence somewhere around 0.4. Cuts, not always and not happy, and steel is like plasticine, Give it to your mother-in-law, let her suffer, 35 rubles is not a pity.
The knife should delight by falling into the food. We draw conclusions. We look to the East. In general, I have not met Europeans thinner than ~ 0.4 - from Arkos to Zwiling.
Second consideration. Wedge on the butt. I know it's bloody. I understand when beginners don't. I don’t understand when people with experience don’t want to take this obvious step in geometry. I remember Tramontina again, but what’s there - almost any knife with a saucepan name in a supermarket is more expensive than 500 rubles. already worthy of getting a tapering butt. With us, it's not always the case.
Moreover, for some reason, many people bring experience from the willingly outdoor area into the kitchen, and knives with a butt of 4 mm or so appear in the kitchen. What for? If this is not a chef with a length of >200 mm and a width of >40, why this pointless work of splitting and pushing the product apart. To simply cut, with minimal effort, an average of 1.5 mm is enough. The handle has more, the tip has much less. And here any extra half a millimeter works against the cut. Unless they are justified by other things, for example, large forms - chef, santoku, need some weight of the blade for inertia in "chopping" mode. And on a station wagon up to 15 cm long, in any case, the weight is insufficient for an inertial cannon, and therefore the extra thickness of the butt works against us.
In general - do not be afraid of transverse flexibility, be afraid of oak unsharpness. If the knife is intended mainly for a woman, you can safely remove it from the butt even up to half a millimeter.
Third. Become. I will limit myself to the method of elimination. The popular opinion is “40X13 for the kitchen just right” - well, why are you positioning the kitchen so low? 40X13 and its counterparts in the form of molybdenum-vanadium stainless look at us in any supermarket. But doesn't a handmade knife have to be better? Is it really pleasant to mash it after a kilogram of chopped vegetables? When we have a lot of other, much better pieces of iron. I do not recommend specific brands, I myself in constant samples.
I think that the kitchen, like no other knife area, deserves the best. After all, only here knives work every day. The choice is simple. There are only two ways:
1. Buy a good but not at all affordable price.
2. Make a knife yourself, especially since this site has all the most necessary information for this. Success and good luck)))
