How to make a master sword

1, preparation material: a piece of 15cm* 15cm square paper, which is folded diagonally and unfolded. Taking diagonal crease as boundary and both ends as vertices, folding and unfolding the side diagonal between the left corner and the upper vertex, and then folding and unfolding the side diagonal between the left corner and the lower vertex; The angle folding method on the right is the same as that on the left.

2. Fold up the left two sides along the crease obtained in the second step, fold the middle corner in half, and then fold the erected corner up and down to form a crease; The folding method on the right is the same as that on the left. Turn to the back, turn one of the long corners to the center point, and then turn the two short corners to the center point respectively.

3. Spread the square paper completely, find the big triangular creases on both sides (as shown in the figure), deepen the triangular creases, and then fold inward along the triangular creases.

Imagine one end as a small triangle, fold the top corner to the bottom and fold it again. Fold the two upright corners downward, then fold the two bottom corners of the right corner in half, then fold them along the crease to the bottom edge, and finally fold the upright corner to the right; The angle folding method on the left is the same as that on the right, and the folding direction is opposite.

5. Turn to the back and fold the two long sides in half toward the center line. Open the left and right corners, fold inward along the crease, and tilt slightly to both sides. Fold the hilt up and back (the folding position is parallel to the left and right corners).

6. Fold the two long sides of the hilt to the center line respectively, flatten the included angle formed by opening, and then insert the flattened angle into the interlayer of the left and right corners of the sword for fixation; Then fold an origami sword.

That's what handmade swords do.
