Interconnected outer strands form a sheath, and one or more inner strands form an inner core encased by the sheath. The inner core comprises a non-planar outer surface in contact with the sheath. The strands may be a monofilament or polyfilament material. The interaction between the non-planer outer surface of the core with the interior surface of the sheath can reduce bunching as well as the separation of the strands due to compressional forces. ## Claims ### Claim 1 A compressible rope, comprising: a plurality of interconnected outer strands forming a sheath; one or more inner strands forming an inner core encased by the sheath; and wherein the inner core comprises a non-planar outer surface that radially extends thereabout being in contact with each of the plurality of interconnected outer strands of the sheath. ### Claim 2 (depends on 1) The compressible rope of claim 1, wherein the strands are comprised of hemp, linen, flax, cellulose, carbon, wool, hair, feathers, cotton, coir, jute, straw, silk, sisal, polymers, nylon, Dyneema®, Kevlar®, rayon, orlon, polypropylene, polyesters, polyethylene, aramids, acrylics, copper, iron, steel, stainless steel, bronze, nichrome, carbon, solder, titanium, zinc, silver, gold, tungsten, or aluminum, or compounds or combinations thereof. ### Claim 3 (depends on 1) The compressible rope of claim 1, wherein the sheath is comprised of a plurality of tied, knotted, looped, twisted, braided, or woven outer strands, or combinations thereof. ### Claim 4 (depends on 1) The compressible rope of claim 1, wherein the sheath encases the core while the core is under tension. ### Claim 5 (depends on 1) The compressible rope of claim 1, wherein the plurality of outer strands are distributed uniformly for the entirety of the rope. ### Claim 6 (depends on 1) The compressible rope of claim 1, wherein the sheath comprises discontinuities at random or periodic locations along the length of the rope corresponding with or unrelated to any change in material composition of the sheath. ### Claim 7 (depends on 1) The compressible rope of claim 1, wherein the inner core comprises a single strand or a plurality of strands. ### Claim 8 (depends on 1) The compressible rope of claim 1, wherein the inner core comprises a monofilament or a polyfilament material or a combination thereof. ### Claim 9 (depends on 1) The compressible rope of claim 1, wherein one or more inner strands are tied, knotted, looped, twisted, braided, woven, or any combination thereof. ### Claim 10 (depends on 1) The compressible rope of claim 1, wherein the inner core is under tension after being encased by the sheath. ### Claim 11 (depends on 1) The compressible rope of claim 1, wherein the one or more inner strands are tied, knotted, looped, twisted, braided, or woven uniformly along the length of the core. ### Claim 12 (depends on 1) The compressible rope of claim 1, wherein the inner core comprises discontinuities at random or periodic locations along the length of the rope corresponding with or unrelated to any change in material composition of the inner core. ### Claim 13 (depends on 1) The compressible rope of claim 1, wherein the inner core comprises a roughened surface at least partially along its length. ### Claim 14 (depends on 1) The compressible rope of claim 1, wherein the non-planar surface comprises a plurality of undulations, spirals, depressions, perforations, excrescences, protrusions, protuberances, or papillae at least partially along its length. ### Claim 15 (depends on 1) The compressible rope of claim 1, wherein the non-planar surface occurs periodically, measuredly, irregularly, or sporadically along at least a portion of the inner core. ### Claim 16 (depends on 1) The compressible rope of claim 1, wherein the non-planar surface is comprised of a plurality of non-planar inconsistencies such as knots, bulges, swellings, or lumps at least partially along the length of rope. ### Claim 17 (depends on 1) The compressible rope of claim 1, wherein the inner core comprises one or more rings, loops, bands, or circles distributed intermittently along the length of the rope. ### Claim 18 (depends on 1) The compressible rope of claim 1, wherein the knots, bulges, swellings, or lumps comprise strands of relatively thicker material, tangled masses associated with knots, loosely woven strands, or combinations thereof. ### Claim 19 (depends on 1) The compressible rope of claim 1, wherein the sheath comprises one or more rings, loops, compressions, bands, or circles that are smaller in diameter than any non-planar inconsistencies located on the inner core, and are intermittently distributed along the length of the rope. ### Claim 20 (depends on 1) The compressible rope of claim 1, wherein the sheath and the inner core comprise a static or dynamic interaction such that there is a reduction in the occurrence of unintended bunching, untying, separating, or slipping between the sheath and the inner core at least partially along the length of the rope.
