Hardy tools, also known asanvil tools orbottom tools, aremetalworkingtools used inanvils.[1]
A hardy has a square shank, which prevents it from rotating when placed in the anvil'shardy hole.[2] The term "hardy", used alone, refers to a cutting chisel used in the square hole of the anvil. Other bottom tools are identified by function. Typical hardy tools includechisels andbending drifts. They are generally used with a matchingtop tool.
Different hardy tools are used to form and cut metal. The swage is used to make metal a specific cross section, usually round for final use as nails, bolts, rods or rivets. The fuller is used to stretch or help bend metal, and make dents and shoulders. Many hardy shapes have corresponding hammer like tools with head shapes to help form metal, called top tools, for example a V-shaped swage is used with an inverted V-shaped hammer like top tool to form iron into an angle shape.
