1. A capillary for performing ball bonding, the capillary comprising:
a body defining a lumen;
a first blade defined in a lower tip of the body;
and a second blade defined in the lower tip of the body and laterally displaced along an outer lower surface of the lower tip from an opening of the lumen for increasing reliability of a ball bonding procedure performed using the capillary, each of the first blade and second blade having a cross-section with a lower end terminating in a downwardly directed point; and
the capillary further comprising an indentation having a pyramid shaped cross-section defined in the lower tip of the body between the first blade and the second blade.
