Abstract

In a method of making cutlery a steel strip is coldrolled to one of the crosssections shown in Fig. 1 and blanks are cut from the strip by a punch and die set having at least two punch and die units. The strip 1 is moved in the direction of the arrow F, Fig. 5 (not shown), into a blanking tool between guides 11 and against a feed-stop 15. The position of the dies 9, 10 in the easing 8 is adjusted by screws 14, and the position of the punches 2, 3 in the holder 4 is adjusted by the screws 7, Fig. 4 (not shown). At each stroke of the press, two knife blades, displaced relative to each other in the direction e-e, are obtained. To facilitate sharpening each die may be made in two parts, located by pins 16 and 17. In a modification, the blanks have mating backs and are formed by a tool, Fig. 9 (not shown), which has a punch 21 and a die 91 formed in the moving part and a punch 31 and a die 101 formed in the stationary part. Spring ejectors 161 are provided in the upper die 91
