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.
