Why Bowstrings Matter More Than the Bow

In a survival scenario, your bow is only as useful as your string.

Wood lasts. Arrows can be repaired.
But the string is the single most failure-prone component.

If your string fails, your bow is useless.

This makes bowstring construction one of the most valuable overlooked skills in traditional archery.

Core Principles of a Good Bowstring

From The Essentials of Archery (1942)

A proper bowstring must be:

Strong
Low stretch
Consistent in length
Protected at wear points

Critical insight:

Stretch is a problem. A bowstring must maintain its length under load.

Best Materials (Ranked for Survival Use)

1. Linen / Flax (Best Overall)

High strength
Minimal stretch
Historically proven

2. Natural Fibers (Emergency Use)

Plant fibers (twisted)
Bark fibers
Sinew (advanced)

3. Modern Substitutes

Paracord (only in emergency)
Nylon (stretches too much)

Basic Bowstring Design

A proper string has:

Two loops (“eyes”)
- Bottom loop → tight fit
- Top loop → adjustable
Reinforced center
- Where fingers and arrow contact
Wax coating
- Reduces wear
- Adds durability

DIY Bowstring Guide: Build, Repair, and Maintain Strings in the Field

Method 1: Simple Flax Twine Bowstring (Fastest Field Method)

Step-by-step

Cut twine:
- Length = bow length + ~18 inches
Separate strands:
- Open the twine about 6 inches at one end
Form the loop (“eye”):
- Split strands into two groups
- Fold and weave them back into each other
Splice:
- Continue crossing strands down the string
- Taper the splice gradually
Reinforce:
- Wrap (whip) the loop with thread
- Wax thoroughly

Result:

Fast, functional string
Ideal for field replacement

Method 2: Three-Ply Twisted Bowstring (Stronger, More Reliable)

This is the real standard.

Concept:

You are making a mini rope.

Setup:

18 strands total (for ~45 lb bow)
Divide into 3 bundles of 6

Process:

Stretch strands between two anchor points
Twist each bundle clockwise
Combine bundles:
- Twist them together counterclockwise
Let tension naturally form a rope

Important:

Opposing twists = strength + stability

Finish:

Splice loop
Wax entire string

Method 3: Reinforced (Tapered) Bowstring

This is the best long-term design.

What’s different:

Ends are thickened
Center remains flexible

Why it matters:

Loops take the most stress
Reinforcement prevents failure

How it works:

Add extra strands near both ends
Stagger them for smooth taper
Twist as normal

Waxing (Critical Step Most People Skip)

“Wax is to a string maker what tar is to a sailor.”

-The Essentials of Archery (1942) by L.E. Stemmler

Why wax matters:

Prevents fraying
Adds water resistance
Increases lifespan

Best option:

Beeswax + resin

Field alternative:

Candle wax
Tree resin

Sizing the String Correctly

A bowstring must be shorter than the bow.

Rule of thumb:

~6–7 inch brace height (“fist-mele”)

This is:

Distance from string to handle when strung

Strength Guidelines (Important)

From the book:

15 strands → up to ~35 lbs
18 strands → up to ~45 lbs
21 strands → up to ~60 lbs
24 strands → heavy bows

Field Repairs & Adjustments

If string stretches:

Twist it tighter

If slightly too long:

Add twists or adjust loop

If fraying:

Re-wax immediately
Reinforce with wrapping

Survival-Level Insight

If you remember nothing else:

The string fails before the bow
You should always carry:
- spare cordage
- wax (or substitute)
You should know at least:
- one fast method
- one durable method

Practical Strategy (Realistic)

Minimum viable skill:

Make a basic spliced string

Intermediate:

Make a 3-ply string

Advanced:

Reinforced tapered string with proper waxing

Final Takeaway

Bowstring construction is not optional knowledge—it’s core infrastructure.

A bow without a string is a stick.
A string without knowledge is a liability.

If you're serious about survival, bushcraft, and self-reliance, this is one of the highest ROI skills you can learn.
