Abstract

The invention describes a cutting knife for a cutting tool for cutting through adhesive beads on glass panes of vehicles, having a cross section that is bent into a U-shape and comprises a first limb, configured as the attachment part, with a receiving opening for attachment to an oscillating drive, and a second limb that is configured as the cutting part and is joined via an intermediate part to the attachment part of the cutting knife, the intermediate part and the cutting part being shaped such that a distance exists in the radial direction between the center point of the receiving opening and at least one cutting edge. The cutting part has, in a middle region between its outer free end and its angled transition to the intermediate part, a lesser width than at the transition and at the outer end. This results in a reduced susceptibility to breakage.
