The _anvil_ is a heavy piece of wrought iron (Figure 49), faced with
steel and having four legs. It has a pointed horn on one end, an
overhanging tail on the other end and a flat top. In the tail there is a
square hole called the "hardie" hole and a round one called the "spud"
hole.

Hole]
_Tongs_, with handles about one foot long and jaws suitable for
holding the work, are used. To secure a firm grip on the work, the jaws may
be heated red hot and hammered into shape over the piece to be held, thus
giving a properly formed jaw. Jaws should touch the work along their entire
length.
The _set hammer_ is a hammer, one end of whose head is square and
flat, and from this face the head tapers evenly to the other face. The
large face is about 1-1/4 inches square.
The _flatter_ is a hammer having one face of its head flat and about
2-1/2 inches square.
_Swages_ are hammers having specially formed faces for finishing
rounds, squares, hexagons, ovals, tapers, etc.
_Fullers_ are hammers having a rounded face, long in one direction.
They are used for spreading metal in one direction only.
The _hardy_ is a form of chisel with a short, square shank which may
be set into the hardie hole for cutting off hot bars.
_Operations._--Blacksmithing consists of bending, drawing or upsetting
with the various hammers, or in punching holes.
