Specially designed hacksaws cut through metal and other hard materials. Never use power tools or any other handsaw tools that are not specifically designed for metal cutting as doing so can result in personal injury and damage to the tools as well. It is important to use the proper technique to ensure a good cut and to promote safety when using the hacksaw. Always purchase hacksaw blades designed for your particular application.

Install the proper metal cutting blade on the hacksaw and fully tighten the wing nut located on the front of the hacksaw that holds in the blade.
Measure the area on the metal that needs to be cut with a measuring square and use a marker/metal scribe to make the cutting line. Secure the metal piece with the bench vise, making sure that the metal is lined up equally within the jaws of the vise. Large sheet metal stock may need to be held securely to the workbench with C-clamps.
Hold the handle of the hacksaw with one hand, laying the index finger across the top portion of the saw for better guidance while wrapping the thumb around the top opening of the handle. Use the other hand to grip the front angled portion of the hacksaw frame, near the wing nut.
Cut the metal piece with a forward sweeping motion, picking the blade up from the metal when retracting the saw back towards you. Do not saw the metal using a constant back and forth motions as this will cause shoddy cuts and premature blade wear.
Use the flat side of a metal file to remove burrs and fix any uneven portions of the metal. Use the same forward sweeping motion used to cut the metal and do not angle the file in a manner that would cause damage to the uniformity of the cut.
