The present invention relates to a method of manufacturing a mixer blade, and more particularly, by processing the same blade by simple bending, it can be manufactured by easily changing the number of blades (blades) with a combination of parts, and when manufacturing a mixer blade In order to reduce fluctuations in the angle and spacing of the blades (blades) depending on the operator, wedges are placed on the blades (blades) to fit into each groove, thereby minimizing the deformation caused by the operator.
