Abstract: A sharpening device, for the saw chain of a motor chain saw, with a holding device for a sharpening element which is arranged in the region of the reversing radius and is curved approximately concavely with respect to the center of this reversing radius. The sharpening element is seated upon an adjustment lever which is pivotable in a direction toward the saw chain. This lever cooperates with a screw device which determines the feed path of the sharpening element. An actuating handle is provided for the feeding of the sharpening element; this handle is arranged on that side of the housing of the chain saw located remote from the free reversing end of the guide bar of the saw chain. The actuating handle is preferably releasably secured in the grasping range of the front handle of the chain saw.

Abstract: A method of producing cutting teeth for a chain saw each of which has a tooth roof and a base body cranked relative to the tooth roof along a substantially sharp edge. The method includes using as starting material a flat band which at least on one flat side of the flat band has a ridge-shaped projection extending in the longitudinal direction of the flat band. The method further includes cutting the band transverse to its longitudinal axis into sections so that each section has an overall size just sufficient for the formation of a cutting tooth to be formed, while the ridge-shaped projection divides each section into a shorter end portion and a longer end portion. The shorter end portion is bent to form the tooth roof, and the longer end portion is provided with a crank relative to the tooth roof.
