Cordage Applications
Part of Knots and Cordage
Knowing how to make rope and tie knots is only valuable if you know what to build with them. This guide covers the practical, life-sustaining applications of cordage — from trapping food and hauling water to building tools and securing shelter. These are the projects that turn raw rope into survival.
The Cordage Priority List
When cordage is limited (and in a post-collapse world, it always is), focus production on the highest-impact applications first.
| Priority | Application | Cordage Needed | Impact |
|---|---|---|---|
| 1 | Shelter lashing | 15-30 m | Immediate — exposure kills in hours |
| 2 | Snares and traps | 5-15 m | Food within 24-48 hours |
| 3 | Fishing line | 5-10 m | Reliable protein source |
| 4 | Tool hafting | 2-5 m per tool | Multiplies labor efficiency |
| 5 | Carrying/hauling | 10-20 m | Transport water, wood, game |
| 6 | Net making | 50-100 m | Large-scale food gathering |
| 7 | Clothesline/drying line | 5-10 m | Food preservation, hygiene |
| 8 | Defensive perimeter | 20-50 m | Trip lines, alarms, barriers |
Application 1: Tool Hafting
Hafting is the process of attaching a working head (stone blade, bone point, metal edge) to a wooden handle. Without hafting, your tools are limited to hand-held rocks and sticks. With hafting, you can build axes, hammers, spears, hoes, and knives that multiply your force and reach.
Basic Hafting Method
Step 1. Select a handle: a straight hardwood stick, 40-80 cm long, 3-4 cm diameter. Green wood is acceptable but dry hardwood is stronger.
Step 2. Prepare the head socket. For a split-end haft, use a knife or sharp rock to split the top 5-8 cm of the handle. For a notch haft, carve a notch in the side of the handle to seat the tool head.
Step 3. Seat the tool head into the split or notch. It should fit snugly without wobbling.
Step 4. Bind with cordage. Wrap tightly below the split (to prevent further splitting), then wrap over and around the tool head in a crisscross pattern. Use at least 10-15 tight wraps.
Step 5. For a permanent bond, apply pine resin or hide glue over the binding. This waterproofs the joint and prevents the cordage from loosening.
Hafting Cordage Selection
| Cordage Type | Suitability | Notes |
|---|---|---|
| Rawhide strips | Excellent | Shrinks tight when dry, very durable |
| Sinew | Excellent | Strongest natural fiber, dries hard |
| Plant fiber (2-ply) | Good | Adequate for light tools, replace regularly |
| Wet inner bark | Good | Shrinks as it dries, good for initial binding |
| Paracord | Excellent | If available, ideal for all hafting |
Tool Safety
A hafted tool with a loose head is more dangerous than no tool at all. Test every hafted tool by swinging it firmly 10 times before use. Re-check bindings before every work session. A flying axe head can kill.
Application 2: Carrying and Hauling
Rope transforms your ability to move materials. Without it, you carry things in your arms. With it, you can drag, sling, bundle, and hoist loads far beyond what your arms alone can manage.
The Travois
A travois is the simplest load-hauling device — two long poles with a platform lashed between them, dragged by a person or animal.
Step 1. Cut two poles, 250-300 cm long, 5-8 cm diameter.
Step 2. Lash the narrow ends together using a shear lashing, leaving about 30 cm of pole extending past the lashing. This is the pull handle.
Step 3. Spread the butt ends apart (they will drag on the ground).
Step 4. Lash 3-5 crossbars between the poles, starting about 80 cm from the pull end, spaced 30 cm apart. Use square lashing.
Step 5. Weave additional cordage or branches between the crossbars to create a platform.
Step 6. Load cargo onto the platform and lash it down. Pull from the narrow end.
Capacity: A well-built travois can carry 50-100 kg across terrain where no wheeled vehicle could go.
The Tumpline
A tumpline is a carrying strap that transfers pack weight from your shoulders to your forehead and neck — where your spine can bear it most efficiently. Indigenous peoples across the Americas used tumplines to carry loads of 40-60 kg over mountain trails.
Step 1. Braid a wide strap, 5-8 cm wide, 60-80 cm long. Use the widest, flattest cordage available — bark strips, woven plant fibers, or fabric.
Step 2. Attach two longer cords (150-200 cm each) to the ends of the strap.
Step 3. Use the long cords to wrap and secure the load (bundle of firewood, basket, pack).
Step 4. Place the wide strap across your forehead. Lean forward slightly. The load rests on your back, supported by your neck and spine.
Rope-Based Water Carry
Without containers, cordage can help you transport water.
Method: Braid a net cradle for a large leaf bundle, hollowed log section, animal stomach, or clay-lined basket. The net prevents fragile containers from breaking during transport. Alternatively, weave a very tight basket from cordage and line it with pine pitch to make it waterproof.
Application 3: Fishing Systems
Cordage is essential for every fishing method beyond hand-grabbing.
Hand Lines
The simplest fishing rig: a line, a hook, and bait.
Step 1. Make a fine 2-ply cord, 3-5 m long, as thin as possible while still strong enough to hold the target fish. For panfish and trout, 1-2 mm diameter is sufficient.
Step 2. Attach a hook — carved bone, bent wire, thorns, or a gorge hook (a small stick sharpened on both ends, tied in the middle).
Step 3. Add a weight 30 cm above the hook — a small stone lashed to the line.
Step 4. Wrap the line around a wooden frame (hand reel) for storage and casting.
Trotlines
A trotline is a long main line strung across a water body with multiple shorter hook lines (droppers) hanging from it. It fishes passively while you do other work.
Step 1. String a main line (10-30 m) across a stream or along a bank, tied to stakes or trees at each end.
Step 2. Tie dropper lines (30-50 cm each) every 1-2 m along the main line, using a simple overhand loop.
Step 3. Attach a baited hook to each dropper.
Step 4. Check the trotline every few hours. A 20-hook trotline can catch 5-10 fish overnight with no further effort.
Gill Nets
A gill net is a wall of mesh suspended in water that catches fish by their gills as they try to swim through. Net-making requires large quantities of cordage but produces food at a scale that no other method matches.
Mesh size determines target species:
| Mesh Size (stretched) | Target Fish |
|---|---|
| 2-3 cm | Minnows, baitfish |
| 5-7 cm | Panfish, perch, trout |
| 8-12 cm | Bass, catfish, pike |
| 15+ cm | Large fish, salmon |
Application 4: Defensive and Camp Security
Rope provides early warning systems and passive defense.
Perimeter Trip Lines
Step 1. Run a cord at ankle height (15-20 cm) around your camp perimeter, tied between trees or stakes.
Step 2. Hang noise-makers from the line every 2-3 meters — tin cans with pebbles, shells, dry seed pods, or small bells if scavenged.
Step 3. A single trip or touch anywhere on the line shakes the entire perimeter and alerts you.
Snare Alarms
Step 1. Set a spring snare (see Snare Building) at approach paths to your camp.
Step 2. Attach a noise-maker to the trigger mechanism. When tripped, the bent sapling releases with a snap, rattling the noise-maker loudly.
Step 3. This serves double duty — it may catch small game while also alerting you to movement.
Overhead Storage
Hanging food and supplies from a high line protects them from animals and flooding.
Step 1. Throw a line over a high branch (5+ meters up) using a rock weight.
Step 2. Attach your food bag to the line with a bowline.
Step 3. Hoist the bag to branch level and tie off the line at the base of the tree. The bag should hang at least 3 meters off the ground and 2 meters from the trunk to defeat climbing animals.
Application 5: Shelter and Construction Cordage
Beyond basic lashing, cordage serves several specialized shelter roles.
Ridge Lines
A taut line strung between two anchor points, used to hang tarps, lean-to roofs, or drying lines.
Best knot combination: Bowline at one end (fixed anchor), trucker’s hitch at the other end (adjustable tension). This lets you tighten the line with 3:1 mechanical advantage.
Guy Lines
Angled lines from shelter peaks to ground stakes that prevent lateral movement in wind.
Best knot: Taut-line hitch at the shelter end (adjustable), half hitch at the stake end. The taut-line hitch lets you re-tension lines after rain or wind without retying.
Tarp Grommets
When a tarp has no grommets, wrap a small stone in the tarp corner and tie cordage around the bulge. This creates a secure attachment point without puncturing the material.
Cordage Maintenance
Natural cordage degrades. UV exposure, moisture cycles, abrasion, and biological decay all weaken plant-fiber rope over time.
| Threat | Effect | Prevention |
|---|---|---|
| UV sunlight | Fibers become brittle | Store rope in shade when not in use |
| Repeated wetting/drying | Fibers weaken and fray | Dry rope thoroughly before storage |
| Abrasion | Outer fibers wear through | Pad rope where it contacts sharp edges |
| Mold and rot | Fibers decompose | Never store wet rope in a bundle |
| Insect damage | Fibers are eaten | Store with aromatic herbs (cedar, sage) |
Inspection routine: Before every critical use, run the rope through your hands slowly. Feel for thin spots, stiff sections, or areas where fibers have separated. Any weak point can fail under load. Cut out damaged sections and re-splice, or retire the rope to non-critical uses.
Replacement schedule: Natural plant-fiber rope used outdoors should be replaced every 2-4 weeks for load-bearing applications. Rope used only for tying bundles or non-critical binding can last months.
Key Takeaways
- Prioritize cordage production by survival impact: shelter first, then snares, then fishing, then tools.
- A travois can haul 50-100 kg of material that you could never carry in your arms. Build one early.
- Trotlines fish for you while you sleep — 20 hooks can catch 5-10 fish overnight with zero active effort.
- Haft every cutting and striking tool. A loose tool head is more dangerous than no tool at all — test before every use.
- Natural cordage degrades rapidly outdoors. Inspect before every critical use and replace load-bearing rope every 2-4 weeks.
- A perimeter trip line with noise-makers is the simplest and most effective camp alarm system.
- The trucker’s hitch combined with a bowline is the most powerful line-tensioning system — use it for ridge lines and guy lines.
