Which tool or method should not be used to cut control cables?

• A. Wire cutters
• B. Hacksaw
• C. Torch
• D. Bandsaw

Answer: (C)

When cutting a control cable, you want to preserve the cable’s strength, geometry, and insulation. A torch introduces intense heat that can create a heat-affected zone, weaken or anneal the steel strands, melt or damage coatings, and even start a fire if nearby materials ignite. Mechanical cutting tools—like wire cutters, a hacksaw, or a bandsaw—slice through the cable without adding heat, making them the appropriate choices depending on the cable size and type. So, the torch should not be used.
