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.
