The invention relates to an apparatus for cutting plastic profiles with a knife which is guided transversally to the profile and comprises a cutting section having a blade and a holding section, with the cutting section extending substantially parallel to the blade and having a larger thickness than the holding section. In order to achieve the cleanest possible cut in which the profile is deformed to an only very low extent at the cutting surfaces, it is necessary that the cutting section is provided with two guide surfaces which are parallel to each other and to the knife plane and the blade is delimited by two transition zones which are arranged in a curved manner in the cross section and converge tangentially into a guide surface each.
