Thanks to the Japanese art of origami from paper, you can create a practically any bulk thing, sometimes even functioning. One of these things are Syricins - special Japanese throwing knives that samurai hid in the sleeve. With the help of Origami technology, the deadly weapons are converted into a fun children's fun.
There are two types of surrogues that can be created with their own hands - four- and octagonal. To create the first, a sheet of stationery paper A4 will need to be folded in the form of a square and divide into two halves so that two equal quadrilaters come out. Make one of the halves of the square in such a way as to get a very narrow rectangular piece. For this, opposite angles bend to the corners opposite to each other. After that, the turn of two other corners will come. They should be bent in such a way that the lines of their folds are at an angle of 90 degrees to the first lines of bend. It turns out two rectangular triangles. With the second rectangle, you need to repeat the same manipulations so that parts of the future of the Syricen were perfectly accurate as if mirrored. It is time to turn one half with these triangles down and put under the second. The corners of the one that the bottom should go under the center of the top, smoothly under the resulting triangles. At the bottom, before you have to bend the paper in the height of the resulting triangles. It remains to connect two halves of Syricen, turning their upper part down. The corners of the bottom should be beatened under the triangles exactly in the middle.Origami not only helps to create various funny toys from paper, but also train your fingers, memory and develops imagination, and the smallest helps learn patience and perfection.
