A common sign of damage to a kernmantle rope is a depression in the kern. Kernmantle rope is constructed with an inner core, known as the kern, and an outer protective layer, the mantle. The integrity of the kern is crucial for the rope's strength and performance. When a depression occurs, it indicates that the inner fibers may have been compromised, which can significantly reduce the rope's load-bearing capacity. This inward deformation often suggests that the rope has been subjected to excessive force or has experienced internal damage that is not visible externally.

While frayed ends, color changes, and unusual odors can also suggest wear and tear, they may not always be definitive indicators of critical damage to the rope itself. In contrast, a depression in the kern is a clear and specific sign that the structural integrity of the rope has been affected, and it warrants immediate attention and potential replacement.
