The invention is directed to a clamping system for knives with angular cross-sections, especially suited for agricultural cutting operations in which a portion of the length of the sidepiece extending the cutting edge of the knife protrudes over the knife holder when the knife is clamped, with the clamping element engaging the knife in the area of its angular bend. This system allows for a reduction of knife thicknesses while maintaining other desirable characteristics, and provides the knife with greater strength in the area stressed by bending as compared with the unclamped position of the knife.
