Fig. 141 shows three varieties of tongs much used in blacksmithing, though there are many special forms for holding peculiarly shaped forgings.
(1) Top and bottom swages, for rounding.
(2) Top and bottom fullers, for necking.
(3) Hardie, for cutting off.
(4) Flatter, for smoothing.
(5) Hot chisel (thin edge), for cutting hot iron.
(6) Cold chisel (thick edge), for cutting cold iron.
Fig. 142. - Anvil Tools.
(7) Round punch, for punching holes in hot iron.
(3) Heading tool, for forming a bolt head.
The stems of the bottom swage, bottom fuller, and the hardie, fit in the square hole in the anvil. The heading tool has a metal handle, and the remaining tools in the figure have hickory handles.
Fig. 143 shows a swage block, a very useful adjunct to the anvil in shaping and bending bars of any shape.
Many sizes of the tools shown and many tools for special work, as chain making, are not uncommonly seen in a well-equipped shop.
Anvil tools are made of a tough grade of medium-carbon crucible cast steel, and they should be harder than forgings.
