The present invention relates to a double-edge blade razor using two identical double-edge blades, and the razor includes: a handle; a frame coupled to one end of the handle; a spacer disposed above the frame; a top cap mounted at the top of the spacer; a first blade fixedly coupled between the frame and the spacer; and a second blade fixedly coupled between the spacer and the top cap, wherein the first blade is coupled and fixed to the razor and then at least partially supported on a top surface of the frame and a bottom surface of the spacer and thus has a first profile that is convexly curved upwardly between cutting edges at both ends thereof, and the second blade is coupled and fixed to the razor and then at least partially supported on a top surface of the spacer and a bottom surface of the top cap and thus has a second profile including a central region that is convexly curved upwardly and a pair of regions that are concavely curved downwardly.
