Survivalist kernmantle
View Patent ↗An improved kernmantle cord in part comprises 550-Paracord manufactured to exceed MIL-STD-C-5040H Type III. The improved kern at the core includes three nylon fibers in each of seven yarns, one continuous filament of waterproofed paraffin-waxed jute twine fiber tinder, one continuous abrasion-resistant nylon or fluorocarbon monofilament, and one continuous copper wire. The monofilament is strong enough for 50# test, yet small enough not to adversely impact the pliability of the cord as a whole. The copper wire itself may be multistrand or braided to improve flexibility or solid to provide more body. The mantle sheathing is of woven nylon and provides abrasion resistance for the whole cord, and functions as an electrical insulator for the copper wire and fireproofing for the paraffin-waxed jute twine fiber tinder.
1. An improved kernmantle cord, the improvements comprising:
an improved kern that includes:
a plurality synthetic thread fibers braided into a parallel number of yarns that principally make up a core;
a continuous full-length strand of jute twine fiber tinder waterproofed with paraffin-wax and added to said core;
a continuous full-length strand of abrasion-resistant and clear and transparent nylon or fluorocarbon monofilament and added to said core; and
an improved woven-thread mantle sheathing that is widened and supplemented along its continuous full-length and that accommodates additional threads that increase the diameter of the improved kern, and without significant gaps between threads in the mantle sheathing that would otherwise expose or allow parts of the improved kern to extrude, and environmental protection from abrasion and pliability of the improved kern.
2. The improved kernmantle cord of claim 1 , further comprising and disposed with the kern and fully within the mantle:
a continuous metal wire that runs inside the full-length of the improved woven mantle sheathing;
wherein the mantle further provides electrical insulation for the continuous metal wire.
3. The improved kernmantle cord of claim 2 , further comprising and disposed with the kern and fully within the mantle:
a plastic coating applied to the surface of the continuous metal wire, and protecting the material from corrosion, and for mitigating any wire breaks;
wherein the plastic coating further provides a degree of electrical insulation for the continuous metal wire.
4. The improved kernmantle cord of claim 2 , wherein:
the continuous metal wire comprises an alloy and sized to have an electrical resistance in a range that will heat to an ignition temperature for cellulose when less than 12″ of its length is connected to a battery less than or nominally equal to 12-volts.
5. The improved kernmantle cord of claim 2 , wherein:
the continuous metal wire is a type that is braided or stranded for pliability and flexibility.
6. The improved kernmantle cord of claim 2 , wherein:
the continuous metal wire has a single solid core that significantly reduces the overall pliability and flexibility of the improved kernmantle cord.
7. The improved kernmantle cord of claim 2 , wherein:
the abrasion-resistant and transparent nylon or fluorocarbon monofilament has at least a fifty pound test rating.
8. The improved kernmantle cord of claim 2 , wherein:
the filament of jute twine fiber tinder waterproofed with paraffin-wax is no more than two millimeters in outside diameter.
9. An improved kernmantle cord of 550-Paracord, the improvement comprising:
a kern at the core that includes:
a plurality of synthetic fibers twisted into each of several full-length yarns;
a continuous filament of jute twine fiber tinder waterproofed with paraffin-wax and not exceeding two millimeters in diameter;
a continuous abrasion-resistant and clear and transparent nylon or fluorocarbon monofilament with at least a fifty pound test rating;
a continuous length of metal wire not exceeding one millimeter in diameter;
a plastic coating applied to the surface of the metal wire, and protecting the metal material from corrosion, and for mitigating any wire breaks, wherein the plastic coating further provides a degree of electrical insulation for the continuous length of metal wire; and
an improved woven synthetic-thread mantle sheathing that includes synthetic threads disposed within that accommodate all longitudinal elements of the entire kern without leaving significant gaps in the mantle sheathing, and afford abrasion protection and pliability;
wherein the mantle further provides additional electrical insulation for the metal wire.
10. A paracord, comprising:
at least one strand adapted for fire-starting and tindering;
at least one strand adapted for inclusion in a fishing line, leader, and tippet;
a number of strands in combination adapted for roping with at least a 550-pound breaking strength; and
a single woven covering that sheaths the above together into a single pliable cord;
a single length of the whole is twisted, looped, knotted, and otherwise fashioned into a bracelet adaptable to the wrist of a user; and
a strand of metal wire included within said single length.
