A rhomboidal blade includes a blade footing ( 2 ) of rhomboidal cross section and a blade body ( 1 ) for axial turbo engines is worked out from a solid blank ( 3 ) by machining. The blank ( 3 ) is cut off as a bar from a hot-rolled, bar-shaped input stock, whose cross section has the shape of a rhomboid which is adapted to the shape of the cross section of the rhomboidal blade footing ( 2 ). The blank is larger on all size than the maximum cross section of the blade by only the minimum oversize ( 5 ) for machining.
