1. A hand-saw blade for making a cut in a free edge of a workpiece to be sawn, said cut being defined by the two sides of an angle, characterised in that it comprises two planar end segments which are respectively a guiding segment (7) having a smooth leading edge (8) and an operative segment (11) having a toothed leading edge (12), the planes of these segments making between each other an angle (alpha) equal to the angle of the cut to be obtained, and an intermediate segment (14) having approximately and L-shaped section whose wings (16, 17), which make an angle (alpha) therebetween, extend the planes of the respective end segments and have respectively a smooth edge (18) with a width of the wing (16) which decreases in the direction of the end operative segment (11), and a toothed edge (19) with a width of the wing (17) which increases in said direction.
