The hole through these anvils is used to support a beckorn (beak iron) or chain swage that is wedged into place.
These tools look a little like an upside down parrot's beak and have rounded surfaces to dress the weld on the inner surface of a chain link.
Matching top swages on hinges were also used to finish the shape.
The hardy hole would often support a bending fixture.
