When inspecting a kernmantle rope by feel, what would a depression in the kern feel like?

During an inspection of a kernmantle rope by feel, a depression in the kern indicates an irregularity in the rope's construction. This is often perceived as a flat spot or a lump. The kern, which provides the primary tensile strength in the rope, should maintain its round shape. A flat spot or lump suggests that there may be damage or an area where the inner fibers are compromised.

In terms of rope safety and reliability, identifying such irregularities is crucial, as they can lead to failure during use. A smooth and even thermal consistency in the kern is expected, so feeling a flat or lumpy depression serves as a significant indicator to further assess the condition of the rope before its next use.

Other sensations such as a crackling feeling or a hotter spot may indicate different forms of damage, such as abrasion or excessive wear, while an oily spot would suggest contamination. These features can also affect the integrity of the rope, but the specific identification of a flat spot or lump directly correlates with a physical defect in the kern that needs immediate attention.
