1. A method for producing a surgical instrument for grasping, holding or guiding a needle, comprising the steps of:
a) providing a first arm part and a second arm part, wherein the first arm part and the second arm part each have a distal holding jaw having a recess and each have a depot in a free end of the distal holding jaw;
b) inserting a first hard metal insert into the recess in the distal holding jaw of the first arm part and inserting a second hard metal insert into the recess in the distal holding jaw of the second arm part;
c) joining the first arm part and the second arm part, wherein the first arm part and the second arm part are pivotably mounted relative to one another at an articulation in a joined state;
d) filling the depot of the first arm part and filling the depot of the second arm part with a braze in each case; and
e) brazing the first hard metal insert inserted into the recess in the distal holding jaw of the first arm part to the first arm part and brazing the second hard metal insert inserted into the recess in the distal holding jaw of the second arm part to the second arm part, with the aid of the braze in each case,
wherein, after step e), the method further comprises a step f) removing the depots.
