This lower end preferably has a transverse cross section shaped as a trapezoid with an apex angle gamma and is upwardly and outwardly tapered at an angle alpha . The flanges located on the rear side of the blade are manufactured from the same piece of material as the blade and define a slot which opens upwardly and outwardly at an angle to the direction of the longitudinal axis of the tool and the symmetrical plane of the blade. A method the slot defined between the flanges has a transverse cross section which tapers inwardly at an angle delta and may be formed by deforming the blade.
