Learning how to make a paper knife is easy when you utilize both video instructions and online origami diagrams.
Folding a Kunai Knife
Supplies needed: 2 squares of paper, one slightly larger than the other, and tape
- Fold your smaller piece of paper in half diagonally to form a triangle.
- Fold in half again to form a smaller triangle and crease. Unfold.
- Fold the right side down so the edge meets the center crease.
- Fold again to the left, and once more to complete the fold.
- Tuck the bottom tails into the little pouch formed at the bottom.
- Now, turn the triangle on its side and squish down to form a kite shape.
- Complete the blade by flattening
- Flip over and tape the backside to reinforce the seam and set aside.
- Now for the handle. Roll your larger square of paper into a straw and tape the seam.
- Flatten just about half of the paper straw, and fold down at a 90 degree angle.
- Make a series of 90 degree folds to create the loop at the end of the handle.
- Tape the loop to secure.
- Insert the handle to the bottom of the blade. Tape to secure.
Congratulations on your new paper kunai!
The kunai knife is a commonly known ninja weapon. It does not look like a typical knife today. This knife had multiple purposes in ancient Japan, from gardening to weaponry. The kunai knife diagrams are dominant in Naruto origami, based on the popular Japanese anime television series.
A kunai knife has a sharp, pointed head that looks like a spear. Unlike a paper sword, the handle of a kunai knife is short and has a looped hole at the end. The kunai knife is an intermediate level project. While the folds are fairly easy, the knife has many steps. Follow directions in a diagram or watch video tutorials on useful origami websites like the following:
- Find two versions of the kunai knife at Instructables.com. The Paper Kunai Knife tutorial shows how to make the knife using a pencil and rectangular sheet of paper, while the Origami Kunai set of instructions offers a way to make the knife using a square piece of paper.
- Get a tutorial diagram for a kunai knife at deviantArt.com. Click on the diagram to make it larger. It relies heavily on origami symbols with few written explanations, so make sure you know what each symbol represents.
- Origami Austria has a PDF diagram that includes both visuals and written instructions for making a kunai knife.
