• To make a sturdier handle, insert a chopstick or pen barrel before wrapping with paper. This helps prevent bending and breaking over time.

Keep folding until you can’t fold anymore, then tuck the extra paper at the bottom inside the blade. It should resemble a tall, skinny triangle. To make the handle, simply roll a larger square paper into a thin tube. Insert the end into the open bottom of the blade and secure it with a piece of tape.

Paper Kunai Knife

Introduction: Paper Kunai Knife

In this instructable I will be showing you how to make a kunai knife out of paper. This type of knife has become famous in many popular TV shows, such as Naruto, and has become the tool of stereotypical ninja everywhere, so it is hard to believe that it was originally derived from a garden trowel used in Japan(Hooray for useless factoids). This version of the kunai knife can actually be thrown if used properly, is almost entirely made out of paper and can be easily recycled when you're done slinging it around.( I would NOT sling one at a person though. They could get hurt, and if they're not they will be seriously pissed off at you). This requires minimal materials and skill to construct, and is fairly easy to use.

• 4 sheets of regular printer paper
• Masking tape
• wool thread(optional)
• paint(optional)
• 3-4 pennies

Step 1: Making the Blade

Take one sheet of paper and fold all four corners towards the middle. Fold over two of the corners again as shown, being sure to line them up exactly with the middle. Fold the result in half along the line of symmetry to make a triangle and repeat with another sheet of paper until you have two triangles.

Step 2: Handle

Take a third sheet of paper and place a pencil on one corner as shown. Roll up the paper into a tight tube, being sure to remove the pencil afterwards, and hold it with masking tape. Don't concentrate on how thin the rod should be. It should be relatively straight and even first, then focus on making it thinner.

Step 3: Attaching the Handle to the Blade

Put the two triangles together as shown, making sure that the result looks symmetrical. Insert the handle into the pocket made and fold up the two corners that are hanging out. Tape together the assembly

At the tip of the knife, tape some pennies inside the pocket. These are to make the knife easier to throw, since it is easier to throw it when it weighs more. Tape up the flap and make sure that the pennies stay in the tip. At this point this project is finished. The rest of the instructable is for applying aesthetics.

Step 4: Attaching the Handle Ring

Create a square piece of paper by folding the fourth sheet of paper into a triangle- like shape as shown and cut off the excess. Fold the square over and over to form a slip of paper just less than one centimeter long, and tape it together. Create a ring on the handle by folding the end over, leaving a hole, and slide the slip of paper through, taping it together to form a circle. This ring is mainly for aesthetic purposes, but can be used to help aid in throwing.

Step 5: Adding Paint

Cover the entire knife with masking tape, leaving no visible part. This step serves to make it slightly waterproof, so that paint can be added.

The type of paint added is entirely up to you. I chose to use water-based black paint, because It was available to me at the time and soaks into the paper, but any color will do for this project, as long as the ingredients do not corrode paper or any of the materials in this knife.

How to Make a Paper Kunai: A Step-by-Step Guide

Table of Contents

Kunai is a traditional Japanese tool that was originally used for farming purposes. However, it soon became popular among the ninja, who used it as a weapon. Today, kunai is a popular weapon that is used in martial arts and can be seen in various movies and TV shows. If you are a fan of ninja or martial arts, you may want to learn how to make a paper kunai.

In this article, we will provide you with a step-by-step guide on how to make a paper kunai. We will also provide you with some tips and tricks to make your paper kunai more durable and realistic.

Before we start, let’s take a look at the materials you will need to make a paper kunai.

• A4 size paper (2 sheets)

You can use any type of paper, but we recommend using printer paper as it is easy to fold and cut.

Now that you have all the materials, let’s get started with the steps to make a paper kunai.

Step 1: Fold the paper

Take one sheet of A4 size paper and fold it in half lengthwise. Crease the paper and unfold it. Now, fold the paper in half widthwise and crease it again. Unfold the paper, and you should have four equal sections.

Step 2: Cut the paper

Take your scissors and cut along the crease that you made in step 1. You should have two equal pieces of paper.

Step 3: Fold the paper again

Take one of the pieces of paper and fold it in half lengthwise. Crease it and unfold it. Now, fold the paper in half widthwise and crease it again. Unfold the paper, and you should have four equal sections.

Step 4: Fold the corners

Take the top left corner of the paper and fold it down to the center crease. Crease it and repeat the same step with the top right corner. Flip the paper over and repeat the same step with the bottom corners.

Step 5: Fold the paper in half

Fold the paper in half lengthwise, bringing the top edge to the bottom edge. Crease it and unfold it.

Step 6: Fold the paper diagonally

Take the top left corner of the paper and fold it diagonally to the center crease. Crease it and repeat the same step with the top right corner. Flip the paper over and repeat the same step with the bottom corners.

Step 7: Fold the paper in half again

Step 8: Fold the top corner

Take the top edge of the paper and fold it down to the center crease. Crease it and repeat the same step with the other side.

Step 9: Form the handle

Fold the paper in half widthwise, bringing the two edges together. Crease it and unfold it. Now, fold the paper in half lengthwise, bringing the top edge to the bottom edge. Crease it and unfold it. Now, fold the paper in half diagonally, bringing the top left corner to the bottom right corner. Crease it and unfold it. Repeat the same step with the other side.

Step 10: Assemble the kunai

Take the second sheet of A4 size paper and repeat steps 1-9. Now, take one of the pieces of paper and apply glue to the handle. Place the other piece of paper on top of it, making sure that the corners match. Apply glue along the edges to seal the kunai.

Congratulations, you have successfully made a paper kunai! In the next section, we will provide you with some tips and tricks to make your paper kunai more durable and realistic.

Steps in Making a Paper Kunai (Continued)

Step 11: Finish the kunai handle

Apply glue to the handle and wrap it with tape. Cut off any excess tape to make it look neat.

Step 12: Decorate the kunai

You can now decorate your kunai to make it look more realistic. You can use markers or paint to add details to the handle and blade.

Tips and Tricks

Now that you have made your own paper kunai, here are some tips and tricks to make it more durable and realistic.

Tip 1: Use thicker paper

Using thicker paper can make your paper kunai more durable. You can use cardstock or construction paper instead of printer paper.

Tip 2: Use glue instead of tape

While tape can be used to seal the edges of the kunai, glue can make it more sturdy. You can use a glue stick or liquid glue to apply a thin layer of glue along the edges.

Tip 3: Add weight to the handle

Adding some weight to the handle can make the kunai feel more realistic. You can use small rocks or sand to fill the handle before sealing it.

Tip 4: Add a sheath

To protect your paper kunai, you can make a sheath out of paper or cardboard. Cut out a rectangular piece of paper, fold it in half lengthwise, and glue the edges to create a pocket for the kunai.

Common Mistakes to Avoid

Here are some common mistakes that you should avoid when making a paper kunai.

Mistake 1: Cutting the paper too small

Cutting the paper too small can make it difficult to fold and can result in a small and fragile kunai.

Mistake 2: Not creasing the paper properly

Not creasing the paper properly can make it difficult to fold and can result in a misshapen kunai.

Mistake 3: Using too much glue

Using too much glue can make the paper soggy and can result in a weak kunai. Apply a thin layer of glue along the edges to avoid this.

By following these tips and avoiding common mistakes, you can make a durable and realistic paper kunai that you can proudly display or use in your martial arts practice.

Variations and Designs

Now that you know how to make a basic paper kunai, you can experiment with different designs and variations to create a unique kunai. Here are a few ideas to get you started:

• Double-sided kunai: Instead of using one sheet of paper, use two sheets of paper to create a double-sided kunai. This will make your kunai more durable and realistic.
• Colored kunai: Use colored paper to create a kunai that stands out. You can also use markers or paint to add more details to your kunai.
• Embellished kunai: Add some extra flair to your kunai by adding embellishments such as glitter, sequins, or stickers.

Remember, the possibilities are endless when it comes to creating a paper kunai. You can customize your kunai based on your preferences and create a design that is unique to you.

In conclusion, making a paper kunai is a fun and easy project that anyone can do. By following the step-by-step guide we provided, you can create a basic paper kunai in no time. We also provided some tips and tricks to make your paper kunai more durable and realistic, as well as some ideas for different designs and variations.
