• wherein the blade and the connector are formed integrally of one piece of material so that the blade is unmovably attached to the connector, and
• wherein the blade is offset with respect to the connector in a longitudinal offset direction by an offset distance;
• wherein the offset distance, the longitudinal offset direction or both of at least one offset-adapted fin of the plurality of offset-adapted fins is different from the offset distance, the longitudinal offset direction or both of at least one another offset-adapted fin of the plurality of offset-adapted fins;
• wherein at least two offset-adapted fins of the plurality of offset-adapted fins have the same offset distance and different longitudinal offset directions.
