Abstract: A cutting tool comprising two cutting members positioned side by side and each having a toothed cutting edge of substantially the same shape. The cutting member being mounted on respect eccentrics of a drive shaft coupled to a motor. The cutting member being guided by respective control links so that the cutting edge of each cutting member prescribes simultaneously in the plane of the toothed edge, simultaneous oscillatory movements in the direction of the toothed edge and in the direction of right-angles thereto. The corresponding movements of the respective cutting members being out of the phase, preferably by 180.degree. and the teeth of each cutting edge being adapted to each cut when moving individually in the direction of the toothed edge.
