A climbing rope composed of a core of strands surrounded by a braided tubular sheath, whereby the tightness of the sheath determines the stiffness of flexibility of the rope. Most of the rope is flexible because its sheath is loose, while, near its end intended for creating the tying knot, there is a stiff section, i.e., a section whose sheath is tighter than along the rest of the rope. The stiff section is abrasion resistant where the climbing rope passes through the piton closest to the climber.
