Abstract

A cutting member of a saw chain has a cutting tooth and a cutting surface having at least one cutting edge. In a side view, looking in a sharpening direction, a first line connects an intersection between an upper edge of a roof section and the cutting surface to an intersection between an imaginary line, which extends parallel to the upper edge, and the cutting surface. A second line connects an intersection between the upper edge and an imaginary displacement of the cutting surface parallel to the contact surface at a position in which a tooth tip of the cutting tooth lies perpendicular to the running direction above a longitudinal center axis of the rearward bearing point, to a point of intersection between the imaginary line and the imaginary displacement of the cutting surface. The contact surface is aligned such that the first and second line extend in parallel.
