Abstract
The cutting member for a saw chain of a motor chainsaw has a base body with a rear portion and a leading portion in a cutting direction of the cutting member. The rear portion and the leading portion extend in the center plane. The base body has rivet openings. The cutting tooth is formed at the rear portion and the depth limiter is formed at the leading portion. The leading portion has a support stay formed by bending at a bending line an upper end portion of the leading portion in a direction out of the center plane. The free end of the upper end portion is bent in a second direction opposite the first direction back across the base body to form an overhang. The overhang has a forwardly and downwardly slanted surface facing away from the base body. The overhang has a length in the cutting direction that is smaller than the width of the support stay. The support stay has a stay edge facing the cutting tooth. The overhang edge has a greater spacing to the cutting tooth than the stay edge. The stay edge positioned higher than the overhang edge.
