ABSTRACT:
In order to improve an angular, U-shaped knife for cutting tools for severing beads of adhesive on window panes of motor vehicles which is drivable about a point of rotation with a small swivel angle and at a high frequency and which comprises an attachment part with a receiving means connectable to a drive shaft coaxial with the point of rotation as first U-leg, an intermediate part as central U-leg and a cutting part as second U-leg, such that while having the same cutting capability as the curved, sickle-shaped knives it is also suitable for completely severing the bead of adhesive throughout its entire width in a corner region, it is suggested that the cutting part be of straight orientation.
