What basic tool is used for cutting heavy cable, cable armor, and conduit?

The hacksaw is the appropriate tool for cutting heavy cable, cable armor, and conduit due to its design and versatility. It features a fine-toothed blade that can handle various materials, offering precision and control during the cutting process. The hacksaw is especially effective for making clean cuts in tougher materials, such as metal conduit or armored cable casing.

In contrast, while a utility knife can effectively cut through some types of cable insulation, it lacks the necessary strength and blade structure to cut through heavy-duty materials such as conduit and thick cable armor. Wire cutters are typically designed for cutting wires and smaller gauge materials, making them unsuitable for larger, more robust constructions. A Sawzall, or reciprocating saw, is more powerful and designed for rapid, heavy-duty cutting but may not provide the control required for tighter spaces or precise cuts found in electrical work. Therefore, the hacksaw stands out as the most suitable and commonly used tool for this specific application.
