摘要： A constructive arrangement in a saw, of the type that comprises a thin laminar portion having a compatible standardized length, a serrated or indented profile being defined on its working edge that configures the cutting blade of the laminar saw itself, the free front free end of said laminar portion being defined by a beveled shape with rounded corners. The back coupling end ( 3 ) of the portion ( 10 ) is comprised of a "V" shaped ( 4 ) axially disposed along the body of the blade ( 10 ), followed by a through-hole ( 5 ) that is centered and aligned with the longitudinal axle of said blade ( 10 ), the through-hole ( 5 ) being disposed equidistant said "V" shaped edge ( 4 ) and small transversal thin tabs ( 6 ) incorporated to the side edge of this laminar portion ( 10 ), in a region immediately in front of the recesses ( 7, 7 a) provided in the respective upper and lower side edges of the laminar portion ( 10 ), thus configuring a neck that prevents the back universal coupling end ( 3 ) from coupling with the rest of the body ( 1, 2 ) of the sawing blade ( 10 ) itself.
