ABSTRACT OF THE DISCLOSURE In producing cutting teeth for a chain-saw, each tooth comprises a sharp-edged top which is offset in relation to the base of the tooth. The starting material is in the form of a preformed flat strip comprising at least one projection, on one flat side of the strip running in the longitudinal direction thereof. The strip is cut off at right angles to its length into pieces corresponding to the length of the finished cutting tooth. Each piece is bent about the projection, through an angle corresponding to the bend between the top of the tooth and the base thereof, to form a sharp edge and thus eliminate the need for any subsequent grinding operation.
