    摘要： The present invention is directed to a method of producing cutlery and a blanking tool to be used in said method of producing cutlery. In the method a sheet metal is placed on a die. The sheet metal is held fixed on the die by means of a holder. In a blanking stroke a punch cooperates with the die to form at least a part of a circumference of a cutlery blank in the sheet metal while the holder holds the sheet metal fixed on the die. Thereafter the sheet metal is released from the die. The blanking tool comprises an upper part in the form of a punch, an intermediate part in the form of a holder and a lower part in the form of a die. The blanking tool further comprises means to move the punch and the holder together as one unit towards the die during a first part of a blanking stroke for the punch. The punching tool comprises means to move the punch in relation to the holder during a second part of the blanking stroke for the punch. The holder abuts the sheet metal placed on the die during said second part of the blanking stroke for the punch.
