Every boy wants to be at least a little like a ninja: to be fast, dexterous, brave, and to be fluent in martial arts and weapons. Having made a real Japanese kunai knife, you can start training in throwing at a target and practicing close fight techniques.

The finished knife according to the proposed origami pattern will look like a real one, with all the features unique to this model. A wide short blade, greatly expanding towards the base, and a handle with a ring. If you attach a rope to it, you can quickly return the weapon back after throwing it. Clean folds will add sharpness to the edges of the blade.

If you use regular office-size paper, the knife will be about 40 centimeters in size. The handle fits well in the palm of your hand. The six sheets of folded paper needed to make it will provide the weight that is important for throwing.

Step 1

For the blade, you need 2 sheets of paper. Place one sheet horizontally.

Step 2

Mark the middle line, connecting the top side to the bottom, and unfold it back.

Step 3

Form the top of the triangle on the left, aligning the halves of the sides on the line created earlier.

Step 4

Fold the sides of the resulting triangle to the center line.

Step 5

On the right, fold the sides into a triangle as well, aligning the sides symmetrically in the middle.

Step 6
Step 7

Fold the shape in half towards itself. Repeat steps 3-6, using a second sheet of paper.

Step 8
Step 9

Connect the two parts by placing one inside the other and positioning them so that the side edges are closed folds.

Step 10

Bend back half of the outer piece, bend it in half, and return it back.

Step 11
Step 12
Step 13

Repeat the same on the other side.

Step 14

Glue the edges.

Step 15

For the handle, take 2 sheets of paper. Place horizontally so that the bottom sheet protrudes a short distance at the top. Connect the bottom sections with glue.

Step 16

Twist the sheets of paper into the tube and secure them with glue.

Step 17

Coat half of the tube with glue and insert it inside the blade until it stops.

Step 18

Bend the side parts of the base of the blade near the tube, tuck them inside, and fix everything with glue.

Step 19
Step 20
Step 21

For the ring, fold one sheet of paper horizontally in half 4 times to form a strip.

Step 22

Form a ring in the center of the line and glue the edges of this kunai part to the base of the handle.

Step 23

Fold the last sheet of paper in half along a long line, coat it with glue, and wrap it around the handle.

Step 24
Step 25

Kunai is ready!

Even when making edged weapons from paper, you can be creative. The knife blade, made of smooth gray paper, will convey the shine of the metal it is typically made from. The color of the handle can convey the texture of the material. You can throw it at the target and practice making accurate hits but don’t forget about safety.
