Abstract: A knife for disk type chip cutter machines with a circular rotatable cutter disk (10) on its first axial side being provided with several knives running from the disk centre to its periphery. An opening (14) is provided in the disk in connection with each knife. The opening (14) has a chip guiding surface to guide separated chips to the other axial cutter disk side. The knife includes a knife carrier, on which the knife is fixed between a first carrier part (18) provided essentially in line with the first axial cutter disk surface and second carrier part (16) extending downwards in the opening from said cutter disk surface into the cutter disk inside and being a part of the chip guiding device. The knife (12) is on its side facing the other carrier part provided with a chip breaking surface (22) passing the other carrier part (16) into the opening and protecting said carrier part from wear in that the separated chips by means of the chip breaking surface are guided in a direction away from the carrier part.
