Hot and cold chisels are used in cutting stock. The blade of the hot chisel is made very thin, while the cold chisel is made blunt to stand the heavy strain in cutting. They are generally made with a hole thru them, called the eye, to receive a wooden handle. These chisels are struck on with a sledge hammer. (See [Figure 12].)
Iron and steel are sometimes smoothed with a tool called a flatter. This tool is struck on with a sledge, and should not be used to stretch iron. Its purpose is only to give the work a smooth finish. [Figure 13] shows a flatter, and [Figure 14] a set-hammer. The set-hammer is always used to smooth and draw stock. All of these tools are made from tool-steel.
A heading tool is made from a flat piece of soft steel with a hole in one end. Sometimes a carbon steel face is welded on. The heading tool is used mostly in heading bolts. Heading tools are made with different sized holes. (See [Figure 15].)

Fig. 16. Top and Bottom Swages.
Swages and fullers are used to smooth and form iron into various shapes. The swages generally have half round depressions in them. They are made in pairs called top and bottom swage. The bottom one fits the square hole of the anvil; the top one has a hole for a wooden handle. (See drawing [Figure 16].) The fullers are also made in pairs called top and bottom fullers. They are used to make depressions in metal. (See drawing [Figure 17].) When referring to swages, fullers, and other tools of this character, blacksmiths speak of anvil tools. Special anvil tools are used in doing various kinds of forging, and are made when needed. The anvil tools should be kept in a tool rack next to the anvil. These tools should be made from tool-steel of about 75-point carbon, or they may be purchased from a dealer. Some tools, such as swages, that do not require continuous service, are made of soft steel.
The anvil tool should have a buggy-spoke for a handle. The handle should stick thru the eye of the hole about one inch and should never be wedged. If the handle is wedged it is more liable to be broken when the tool is struck a glancing blow with the sledge hammer. This is very often the case. The reason the spoke should stick thru the tool is that if it should begin to work off the handle when struck with the sledge hammer, the movement can be seen.
