Hacksaws are used to cut through a variety of materials, such as wood, PVC and metal. The saws are available in either handheld or power varieties. The mainframe of the hacksaw consist of a "U"-shaped metal bracket that holds a thin, steel serrated blade between 8 and 12 inches long. To achieve a clean cut through A2 steel using a hacksaw, you must use the proper hacksaw blade. If the proper blade is not installed, the steel will dull the serrated teeth.

- Fine-tooth hacksaw blade
Unscrew the wing nut located at the top edge of the hacksaw. If a blade is already installed on the hacksaw, slip the end of the blade off of the small metal projection to detach.
Purchase a fine-toothed hacksaw blade, such as 24 or 32, that is designed to cut metal. Wider-spaced blades that will cut through softer metal are not effective on A2 steel. The packaging for the hacksaw blade will specifically say that is will cut steel or hard metal.
Install a new, fine-toothed blade onto the hacksaw by placing the small circular opening on the blade over the metal projection at the base of the saw. Locate the circular opening on the other end of the blade and insert it over the metal projection at the top of the saw. Hold the blade in place with one hand while tightening the wing nut with the other.
Lay the steel on a flat surface and hold it steady with one hand. You can also secure the steel to the table using clamps if desired.
Place the back edge of the hacksaw blade onto the steel and pull it backward to make a small cut. Lift up the hacksaw and return it to the starting position. Pull the blade back again to deepen the cut. Continue doing this until you see a groove start to develop in the A2 steel. This may take a while since A2 steel is stronger than other metals.
Make long back-and-forth strokes along the entire length of the blade, applying pressure each time you push forward. Continue sawing back and forth until you cut all the way through the piece of A2 steel.
Tips and warnings
- If the A2 steel is thicker than a half-inch, saw down until the top of the hacksaw blade is level with the top of the metal. Turn the steel over and begin sawing from the opposite side to complete the cut.
