Files, a traditional metalworking tool, are bars of metal covered with serrations or sharpened scales, and are used to smooth, shape and remove metal. Files range in length from a few inches to more than a foot, and appear in a variety of shapes, including cylinders, triangles and rectangles. Constantly pushing a file across a metal surface causes its scales or serrations to abrade metal surfaces.
The hack saw is a basic hand-held cutting tool with a sharp-toothed blade that is used to shave away and cut through metals. The hack saw features a C-shaped framed attached to a pistol-grip handle. Blades attach to the open portion of the frame and the metalworker pushes the saw back and forth across pieces of metal. The fine, closely grouped design of the blade’s teeth prevent it from catching and halting on tough metal surfaces. Hacksaw blades are categorized according to teeth per inch, i.e. more teeth for harder metal and less teeth for softer metal.
Metalworkers use plastic, wooden or rubber-headed mallets to shape, form and pound metal into place. Whereas metal-headed hammers leave noticeable strike marks on a metal surface, the blow of soft-headed mallets produces few dents and surface blemishes.
The dolly is the antecedent of the anvil; metal is placed upon a dolly and pounded for shaping and smoothing purposes. Dollies may be hand-held or placed on stationary surfaces, such as a table. The curved surface of a dolly allows metalworkers to form malleable metal easily and consistently into rounded forms.
Snips, also called metal shears, are the scissors of the metalworking world. These tools look like bulky scissors with extra-sharp, serrated blades. Snips cut metal roofing, flashing, sheet metal and thin metal plates. Varieties of snips include aviation snips, hawksbill snips and duct snips. Aviation snips, also called compound snips, feature a unique design that takes advantage of leverage to cut manually through thick metal sheets.
