How to make a paper katana sword

Updated February 21, 2017

Origami is the art of making folded designs from pieces of paper. You can make a paper katana sword that will let you pretend to be a ninja---without any of the dangers of a real sword. A sheet of paper and a few common household items are the only items needed. A cutting edge will be used, so an adult should supervise if a child is making the ninja-style sword.

Cut a 20-cm by 10-cm (8-inch by 4-inch) rectangle out of a sheet of computer printing paper with the scissors.

Place the paper rectangle on a table with a 10-cm (4-inch) side facing you.

Fold the left side of the paper rectangle over to the right side. Crease the fold down with your fingers. Repeat this procedure.

Connect the sides of the paper rectangle together using cellophane tape.

Place the paper rectangle horizontally on the table. Fold the upper left corner of the paper rectangle towards the right to form a point. Fold the upper right corner of the paper rectangle towards the left to form a point. Tape the two points together with a piece of cellophane tape.

Cut a 10-by-5-cm (4-by-2 inch) paper rectangle out of a sheet of computer printing paper with the scissors.

Place the 10-by-5-cm (4-by-2 inch) rectangle on the table with the 5-cm (2-inch) side facing you.

Fold the left side of the 10-by-5-cm (4-by-2 inch) paper rectangle over to the right side. Crease the fold down with your fingers. Repeat this procedure.

Wrap the 10-by-5-cm (4-by-2 inch) paper rectangle around the end of the other paper rectangle that does not have a point on it to form a handle

Connect the 10-by-5-cm (4-by-2 inch) paper rectangle to the end of the other paper rectangle with cellophane tape.

Pick up your ninja-style paper katana sword by the "handle" and aim the point at any and all imaginary ninja enemies.

Tip

Construction paper will last longer if substituted for paper.

Warning

Never strike at a person's or animal's face with any paper origami toy you make as this can damage their eyes. Work gloves will prevent getting a paper cut when making your ninja-style paper sword.
