How to make a knife from cardboard. How to make a knife out of paper

Today it is very fashionable to manufacture products based on paper. Toys of this type can completely replace real ones. Take, for example, pistols or knives. Unlike plastic options, paper ones are safe, which is primarily important for children. One of the main attributes of toys for boys is a knife. We recommend that you read the instructions below and learn how to make a knife out of paper.

Knife made of multi-colored paper

To begin with, we will tell you how to make a knife from colored paper. To construct this model of a children's toy, you will need an A4 sheet, a stapler (can be replaced with tape), and scissors.

Making a knife:

We take a sheet, carefully wrap any of the corners, but the edges of the sheet should match. Having made such a fold, you should get an open triangle, cut it off, unfold the workpiece and see a square in front of you. We bend the square three times, while ironing the folds well.
Now we take scissors and make all the edges semicircular, like a kitchen knife. To prevent the workpiece from falling apart, it must be secured with tape or a stapler. Now we take a piece, bend it along its length several times, fix it with the same tape and get the handle of our knife.
Next you need to combine 2 blanks into one solid object. After joining, the craft can be painted.

So we told you how to make a simple knife out of paper. Now you can start making a more complex model.

Kunai Dagger

One of the serious paper products can be called a Kunai knife. The paper art of origami is used to construct it. Before you begin the manufacturing process, you need to find two landscape sheets and several sheets of colored paper.

How to make a ninja knife from paper:

Kunai Dagger

We take a landscape sheet as a basis, fold it and get a triangular shape. Fold the resulting triangle in half, and then unfold the workpiece to its original position.
We wrap the corners to the center line and fold the craft in half. Next, we have protruding ends, which we bend into the resulting pockets and thus form the blade of our future craft.
Pressing the edge in the shape of a pyramid with your fingers, we lift the paper a little to achieve volume. We take a second sheet of paper, roll it into a tube with a small diameter and insert the blade five centimeters deep.
Next, use your fingers or a sharp object to level the edge of the tube and repeat folding several more times. A handle with a tip should form. At the end, we fix the craft.

Many people want to make the craft heavier and put a coin or pebble in the middle. This is how a ninja knife is made, there are many more options for making knives. Many are trying to learn how to make karambit from paper, we will also tell you about that, but a little later.

Pirate knife

Now we will tell you how to make not a karambit knife from paper, but a pirate knife. This craft is perfect for games and theatrical performances.

For production we will need:

cardboard;
regular pencil;
scissors;
glue and markers.

Making a pirate knife:

The pirate knife is ready, for a real look, cover the blade with foil and the handle with colored paper.

Paper butterfly knife

Knowledge of how to make a knife out of paper is not enough in this case, because when designing a butterfly knife, it will take time, patience and some expenses. The craft completely replicates the actions of a real butterfly knife.

What is needed for design:

multi-colored material (you can use thick office paper);
stationery knife and scissors;
glue or tape.

It is also worth knowing that a butterfly knife can be made in several ways.

Manufacturing process in the first way:

We take a landscape sheet as a basis, roll it into a tube and smooth it out well. We cut off the excess ends and get a craft that looks like a blade. We fix the workpiece with tape or glue. Draw dotted lines and cut off the craft.
We cut the workpiece along the marked lines and move all the parts apart. Now let's start rolling the tubes.
From four white and one red sheets of paper, we roll up tubes, after which you need to put one white one into the red one. Now we cut off two identical parts from the red tube, which will resemble wheels in shape, apply glue to them and connect them by winding the ears of one on the other.
We combine three tubes. We cut off the excess part. We mark the holes on the blade, insert one red piece of a red tube there, and glue the other end of the same tube with the ends down. To obtain a stronger structure, you need to stick a white one on the red tube, and it is important to maintain the size. We perform identical actions on the other side of the handle.

As a result, we should have a folding butterfly knife.

Now let's make a butterfly knife using the second method. Before starting production, you need to print out a knife template.

Sample

Designing a knife using the second method:

We cut out all parts of the template, apply it to corrugated cardboard, trace the blank with a pencil and cut it out with scissors. It is better to cut the handle from simple but thick cardboard.
Now we take two thin strips that are cut out of cardboard, grease them with glue and apply them to the inside of the handle parts. We glue part of the handle on top.
Next, take a regular toothpick or an awl and pierce the blade with this object at the bottom of the blade. Now insert the toothpick into the blade; it should stick out only one centimeter. If the protrusions are longer, they need to be trimmed. The resulting structure must be secured with hot glue.
We finish the work with the following action. We place the blade in the body and close the product. Then we pierce the parts near the edge and check that they move freely. And if everything works perfectly, fix the toothpicks with glue.

Swiss knife model

You can also make a Swiss knife out of paper. It received this name because it was used as a weapon in the Swiss army. It was red. The finished craft can be used in gameplay or presented as an interesting gift to fans

The design of a knife is carried out using the following tools and materials:

cardboard, preferably white;
a simple pencil;
bolt with nut or rivet;
glue and needle.

Before explaining how to make karambit from paper, you need to find paper for schematic drawing, a glue stick, and scissors. Boys who play computer games will be interested in making a model themselves. The manufacturing process is very simple:

Sample

download and print the knife drawing;
Using scissors, we cut out all the parts, apply the blanks to drawing paper and trace them with a pencil, while the base needs to be traced eleven times, and the handle twelve times;
cut out the outlined elements, glue all the parts and place them under a press (or under heavy books);
now we take one part of the handle and glue it to the blade;
Having coated the second part with glue, close the other side of the blade.

At the end, we paint the craft and cover it with colorless varnish.

Knife like an Assassin

This model of knife can be made without a template. You will need eight album sheets and tape.

The knife is made in this way:

The knife is ready. Your child will probably ask you how to make such a paper knife 232 times, and maybe more, because the toy turns out to be excellent. In addition to it, you can make sure that the warrior is ready for battle. We described earlier how to make shuriken.

When playing with such a knife, the child will be safe and will not be injured during the game, and this is a guarantee of peace of mind for parents. It’s better to make any of them together with your children; they will really like this activity.

There are several ways to make such toys. For example, you can make a butterfly knife out of paper. This toy can be made in just a few minutes.

What materials will be needed

To make your own safe knife you will need:

several sheets of thick paper 15x20 cm - 2 red, 2 blue, 1 yellow.
sharp scissors;
several wooden toothpicks;
transparent tape.

Also, to assemble a plausible paper knife, you will need to prepare an awl.

Knife blanks

To make a paper knife with your own hands, take a red sheet, fold it in half along the long side and cut it into two equal parts. Fold each piece in half again and fold it into thirds to create a strip about 1cm wide.

Do the same with the second red leaf. You should end up with 4 identical red stripes. In the future, these will be the “handles” of the knife. Wrap the strips with tape to prevent them from unraveling.

Also fold a sheet of blue paper in half and cut it into two parts. Fold one of the halves in half, then in half again, and again. Cut off the end of the resulting wide strip in the form of a knife tip and wrap the resulting “blade” with tape.

From the second blue half, roll up a narrower strip, folding it in half and then three times. Also cut off its blade-shaped end. Insert a second strip into the first to make the “blade” more rigid.

Cut the second sheet of blue paper in half. Roll a wide strip from one of the halves. Cut the blunt end of the “blade” along the edges along the length by 2-3 cm. Insert the blue strip at the bottom of the “blade” perpendicularly and secure it with tape.

How to make a safe knife out of paper: assembly

At the intersection of the “blade” and the strip, make two holes with an awl. Insert a toothpick into the holes. Punch holes in the ends of each of the 4 red strips you made earlier.

Roll a yellow sheet of paper into a thin tube and secure it with tape. Cut two lengths from the tube equal to the length of the red stripes.

Place the red stripes on both sides of the toothpicks. Coat the yellow tubes with glue on both sides, place them between the red stripes in pairs and press down. As a result, you will have two movable handles along the edges of the “blade”.

The final stage

Cut the toothpicks so that they protrude only a couple of millimeters beyond the plane of the paper. Cover them with tape on both sides.

Cut the perpendicular blue strip at the level of the “handles”. A real paper butterfly knife for a child is ready. Depending on the position of the “handles”, the “blade” in such a toy will be open or closed.

Many people are interested in how to make a knife out of paper with their own hands, I will now demonstrate this master class in a step-by-step form with a photo. The craft is not very complicated and is considered slightly childish, for example like, or. It is by making a paper knife that many people learn origami skills. We will need two oblong sheets, one long for the base of the knife, and the other smaller for the limiter. I specifically chose different colors to make it clearer and more convenient for you.

I'll move on to creating the craft right away. Let's prepare the necessary leaves, orange for the base of the knife, pink for the limiter. Determine the size of the orange sheet yourself, the length of the knife depends on this, the size of the pink one can be slightly reduced in the process.

Let's start with the basics. Take the longest rectangle and fold it in half along the long line. We need this to mark the middle.

Unfold the folded sheet. The middle has been outlined.

We bend one side to the middle.

We bend the second one in the same way.

This is what should happen. If the length of the base is too long, you can trim it.

Now you need to make one edge sharp. Fold one corner out of two, like this.

The other corner needs to be folded into the middle.

And finally, insert one corner into the other.

One edge of the knife is ready, this is how it looks, neat and beautiful.

We wrap the other edge of the workpiece inward. This results in two angles.

Then, turn each corner individually inward again. Let's take one.

Let's wrap it up. This is what it looks like.

Fold the second corner inward in the same way and this is what should happen.

This is what the finished homemade base looks like.

Let's move on to the limiter. Take the pink leaf, the smaller one.

Fold it in half along the long side. And mark the middle.

Fold both sides towards the center. And bend the entire workpiece in the center.

Fold the existing strip two-thirds over.

This is what it looks like from above.

Bend the remaining tail in the same way.

Insert the shorter edge into the longer one. At this stage, you can slightly adjust the size of the knife stop.

Combine both parts together. You can pour a little PVA glue onto the crossing of the two parts to secure them.

We managed to make such a beautiful knife out of paper, an interesting origami craft and quite easy.

Nowadays it is considered very fashionable to be able to make all sorts of things out of paper, especially if you use rare techniques. Such items can be an excellent alternative to the real thing, but at the same time be completely safe. This is especially important when it comes to children who are planning a game involving knives. Also, our tips on how to make a knife out of paper will help participants in masquerades and theatrical performances find inexpensive and suitable props.

Knife made of colored paper

The simplest model of a knife is made using a regular sheet of A4 size, double-sided tape or a stapler and scissors.

Follow these steps:

Making a ninja dagger (kunai) from paper

To make such a superhero knife, you should use the origami technique.

Before you start, prepare two regular office sheets of white or colored paper.

Completing of the work:

The ninja dagger is ready.

Advice! If you want to make your paper weapon a little heavier, place pebbles or coins inside the blade.

Pirate knife

A pirate knife for a children's game or theatrical performance is best made from cardboard.

On a cardboard sheet of the required size, draw with a pencil the shape of a pirate's bladed weapon and cut it out. Then attach the cut out sample, trace it on the cardboard and cut it out again. Make sure all edges match.

After the 2 parts are ready, you need to glue them and paint them. Or you can wrap the blade with shiny foil and cover the handle with colored paper.

Making a butterfly knife out of cardboard

When starting to create this type of knives, you should know that this is not an easy task, and it is also time-consuming. But the result will surprise everyone, including children. The paper version will be exactly the same as the real one.

To work you will need the following materials and tools:

White paper;
colored paper;
scissors;
glue;
stationery knife.

Take a sheet of white paper, A4 size, and roll it into a tube, smooth it out. Trim the ends to create a blade. To prevent the structure from unfolding, attach it layer by layer with tape. Draw dotted lines. You need to cut the future craft using them.

Looking at the photo above, mark the workpiece.

The next step is to roll out white sheets (4 pcs) of A4 and red (1 pc) tubes. Place the white tube into the red one.

The red tube should be used like this: 2 identical parts resembling wheels are cut off from it. You need to apply glue to them and connect them by winding them inside one and the other ear.

Mark a hole near the base of the blade. You need to insert one red tube there. And the ends of the second red tube are glued with the tips inward.

To make the handle stronger, glue a white one to the red tube, maintaining the length. Repeat the above on the other side of the handle.

You should end up with a paper version of the butterfly knife.

There is another option for creating a butterfly knife, which uses cardboard or foam board.

The first step is to download the template and then print it.

Let's get to work.

The work on the knife is finished.

Folding Swiss knife made of cardboard

The knife got its name because it was in the Swedish army that they carried such a red bladed weapon. Now we will make a knife - a postcard, which can be used both in the game and as a souvenir.

Do you know that you can make a real kitchen knife out of ordinary cardboard! And at the same time make it as sharp as possible? Don't believe me? Then see for yourself! The idea is new, I have never seen anything like it before. At first I didn’t really believe in the success of this event. As it turned out, it was in vain.

Cut out several rectangles from cardboard (multilayer). Soak in water.

After the cardboard is wet, tear it into small pieces.

Bring the substance to a boil in water.

Drain the remaining water and filter it through a paper filter.

After this, pour the water into a separate container, and then saturate a new piece of cardboard with it. Next, roll out with a rolling pin, getting rid of as much air as possible inside the cardboard.

Tap the surface with a hammer.

We roll up the cardboard gradually, tapping the entire surface. Next, use a press to compress each part. We place our “lavash” on both sides of the grid and press it with a press.

After the cardboard has completely dried (about 1-2 days), outline the outline of the knife and cut out a similar shape from our cardboard.

When sharpening, it is important to go from coarser-grained paper to smaller-grained paper. Then the sharpening will be correct. That's all, the knife is ready. It cuts paper and more with ease! See the video for more details.
