Abstract: A reciprocating parting tool includes a substantially flat parting blade which extends along a direction of travel and has a longitudinal extent along the direction of travel. The parting blade has at least one parting edge which extends substantially along the longitudinal extent and includes at least two edge sections, preferably of different longitudinal extents. At least one of the at least two edge sections is not oriented parallel to the direction of travel. At least one of the at least two edge sections, in particular the edge section with the larger of the two longitudinal extents, has a serrated knife edge with a serration spacing.
