What is a core shot and its risk?

• A. A cosmetic scratch on the rope sheath.
• B. Damage to the rope core visible under the sheath; significantly weakens the rope and increases failure risk.
• C. A knot in the rope.
• D. A measurement of rope length.

Answer: (B)

Core shots occur when the inner rope fibers (the core) are damaged and exposed through the outer sheath. The core carries most of the rope’s strength, so any damage to it weakens the rope substantially. When the core is compromised, the rope can fail more readily under load, especially during a fall or dynamic climber movement, making the risk of catastrophic rope failure much higher. That’s why seeing exposed core or obvious internal damage is a serious safety warning and the rope should be retired or professionally evaluated before reuse. A cosmetic scratch is just surface wear on the sheath and doesn’t indicate core damage; a knot is simply a tie in the rope; a measurement of rope length has nothing to do with structural integrity.
