Abstract
A cutting knife is proposed for the cutting of stacked, sheet-like material. The cutting knife has a wedge shape with one cutting surface and one repelling surface, arranged at the wedge angle to each other, and whose cutting line forms the cutting edge of the knife. According to the invention, the cutting knife is provided with outlet openings for blown air in the region of the repelling surface. In the method for fabrication of the cutting knife, channels are incorporated in the knife holder prior to connecting the knife holder and the hard metal blade of the knife, and due to the arrangement of these parts, the blown air passages are formed in the cutting knife upon connection of knife holder and hard metal blade, emerging into the outlet openings.
