In kernmantle rope, which component primarily protects the core from abrasion?

• A. Core
• B. Kern
• C. Fiber
• D. Mantle

Answer: (D)

In kernmantle rope the outer mantle (the sheath) acts as the protective shield against abrasion. The inner core, or kern, provides most of the rope’s strength, but it sits inside the sheath and is shielded from wear by that outer layer. The sheath is specifically designed to take the rubbing and friction from rope contact with rock, gear, and hardware, which is why abrasion damage is typically seen on the sheath first. The other terms—core or kern refer to the load-bearing internal part, and fiber isn’t a separate protective layer—so they don’t describe the component that protects the core.
