In a mounting arrangement for supporting, in a stepwise adjustable fashion, a cutting blade in a cutting head for working wood or plastic, the cutting blade has at least one cutting edge and opposite side edges with wave-like profile structures and claw elements are mounted on the cutting head and have engagement portions extending into the troughs of the wave-like profile structures for form-fitting engagement therewith. Each wave-like profile structure has a greater length in the direction of the side edges of the cutting blade than the respective engagement portions of the claw elements so that the position of the cutting blade is adjustable.
