PURPOSE: A press blade in a multiple structure for processing an uneven shape is provided to cut a precise shearing area without an additional process by installing the press blade having a plate type cutting blade to an uneven portion to operate a cutting operation successively. CONSTITUTION: A press blade(1) in multiple structure for processing an uneven shape comprises a thin plate(2). Cutting blades are formed to a lower surface of an uneven portion(5). The press blade is made by adding several plates. A slanting difference between a tip(4) of an upper blade and the tip of a lower blade of the press blade is about 1 millimeter. A material is processed by mounting the press blade to a press. A shearing area is formed to the material by the press blade. Shearing areas are cut smoothly by cutting each layer more. Therefore, a precise shearing area is made by cutting the shearing area successively with the slant cutting blade of the uneven portion.
