Bolt cutters are a common tool for cutting steel cables, especially smaller diameters. They work by applying immense pressure to the cable, shearing it apart. To use bolt cutters, simply position the cable in the jaws of the tool and squeeze the handles together. The blades will cut through the cable, leaving a clean, even cut. However, bolt cutters have limitations and may not be suitable for larger cables or hardened steel. In such cases, you may need to resort to other methods like hacksaws or grinders.

Hacksaws are another option for cutting steel cables. They use a thin, toothed blade to gradually saw through the material. To use a hacksaw, secure the cable in a vise or clamp and position the blade perpendicular to the cable. Apply firm, even pressure as you draw the saw back and forth. It may take several strokes to cut through the cable, but hacksaws can handle thicker cables than bolt cutters. However, they require more effort and can be time-consuming, especially for larger cables.
