Learn how to set, shape, and tune snare locks for trapping and fieldcraft. Full beginner to expert guide.
How to Use Snare Locks Safely and Effectively
Snare locks are small mechanical components that let a loop of wire cinch down and hold tension when an animal passes through. They’re simple in design but extremely effective when built, shaped, and tuned correctly.
Grim Workshop snare lock tools are flat, compact, and intentionally designed so you can bend, shape, and tune snare locks in the field using:
-
Your bending tool
-
Your multiwrench
-
Your pliers (if available)
-
Your hands for micro adjustments
This guide explains exactly how to form the lock, how to tune the loop, how to adjust sensitivity, and how to install a snare lock safely and responsibly.
Legal Note: Snaring regulations vary by state and region. This guide teaches tool use and fieldcraft technique, not laws. Check local regulations before setting actual snares.
What a Snare Lock Is
A snare lock is a small metal component that:
-
Slides freely in one direction
-
Locks when pulled the opposite direction
-
Controls loop tightening
-
Holds tension once the loop cinches
-
Prevents backing out
The lock relies on:
-
Angle
-
Friction
-
Wire compression
-
Clean bends
A well-shaped lock is smooth, reliable, and responsive. A poorly shaped lock either doesn’t move… or doesn’t hold.
Essential Tools for Using Snare Locks
The following Grim Workshop tools make the job dramatically easier:
Bending Tool
Shapes the lock’s angles precisely.
Pairs with:

Types of Snare Lock Designs
Simple L-Bend Lock
Most common style for survival snares.
Oval Compression Lock
More controlled grip and smoother travel.
Two-Bend Channel Lock
Good for thicker wire.
S-Hook Lock
Fast in emergencies, but less precise.
Your bending tool creates all of these.
How to Form a Snare Lock (Step-by-Step)

Step 1: Straighten Your Wire
Remove coils, kinks, or waves.
A clean, smooth wire improves lock performance.
Step 2: Insert Wire into the Correct Slot on the Bending Tool
Use a slot that:
-
Holds firmly
-
Doesn’t wobble
-
Doesn’t scrape the metal too harshly
This gives you a clean, predictable bend.
Step 3: Make the Initial 90-Degree Bend
This forms the lock shoulder.
-
Insert wire halfway into the slot
-
Pull the free end sideways
-
Make a clean 90-degree angle
This is the pivot point that allows the lock to slide one way and jam the other.
Step 4: Create the Compression Channel
Slide the wire deeper into a narrower slot.
Bend a very slight inward angle — around 15–25 degrees.
This creates the grab.
If the angle is:
-
Too shallow → lock slips
-
Too tight → lock won’t slide
You want friction, not blockage.
Step 5: Shape the Loop End
On the other side of your lock you need the loop entry:
-
Round it slightly
-
Avoid sharp corners
-
Ensure smooth travel
Use the bending tool to form a gentle curve.
Step 6: Test Fit the Lock
Thread the opposite end of the wire through the lock to form a loop.
The lock should:
-
Slide freely when loop is expanded
-
Grip instantly when pulled tight
-
Not kink or bind
If it binds, widen the channel slightly.
If it slips, tighten the angle a hair.
Micro adjustments matter.
How to Tune a Snare Lock
Tuning determines how the snare behaves when triggered.
Light-Slip Tuned (For Small Game)
-
Bend compression point open slightly
-
Lock barely grabs
-
Loop cinches smoother and quieter
Great for:
-
Rabbits
-
Squirrels
-
Small birds
-
Rats
-
Ground foragers
Firm-Lock Tuned (For Stronger Animals)
-
Tighten compression angle
-
Increase friction
-
Ensure one-way travel only
Great for:
-
Raccoons
-
Ground predators
-
Tougher small game
How to Set Up the Snare Loop

Step 1: Size the Loop
General rule:
-
Small game = 3–5 inches
-
Rabbits = 4–6 inches
-
Squirrels = 2–3 inches
-
Water sets = varies by species
2. Create a small loop with a twig or pencil
-
Find a small twig about the size of a pencil.
-
Wrap your snare wire around the twig two full turns.
-
Twist the tag end of the wire to secure those wraps in place.
-
You’re basically using the twig as a temporary “mandrel” to size the loop.
The goal is to make a small, clean, circular loop that your main snare line can slide through.
3. Remove the twig
-
Slide the twig or pencil out of the wire wraps you just made.
-
This leaves behind a fixed, small loop.
-
This is the eye of your snare — the part the snare line will slide through.
Make sure the loop doesn’t collapse or twist shut.
4. Form your main snare loop
-
Take the long end of your wire and feed it through the small loop you just made.
-
Pull several inches through until you have a large snare loop, sized for the animal you’re targeting.
-
The small loop acts like a sliding lock, tightening when pulled.
This turns your straight wire into a functioning slip-style snare.
5. Anchor the snare
-
Tie or twist the other end of your wire firmly to a solid anchor (tree, root, stake, or log).
-
Make sure the anchor cannot move — this is what actually holds the trapped animal.
-
Set the snare in position on a trail or funnel point.
-
Use small twigs if needed to keep the loop open and properly oriented.
Once triggered, the animal pulls the main line, the loop tightens instantly, and the anchor holds the snare in place.
Step 5: Set the Snare at Animal Head Height
This is key.
Most failed snares are set too high or too low.
| Animal | Snare Loop Size | Height Off Ground |
|---|---|---|
| Groundhog | 5–6 inch snare loop | 2 inches |
| Opossum | 5–6 inch snare loop | 2 inches |
| Fox | 8 inch snare loop | 8 inches |
| Bobcat | 8 inch snare loop | 8 inches |
| Raccoon | 6–8 inch snare loop | 3–5 inches |
| Coyote | 10–12 inch snare loop | 10–12 inches |
| Wolverine | 8 inch snare loop | 8 inches |
| Beaver | 10 inch snare loop | 2–3 inches |
| Wild Hog | Up to 18 inch snare loop | 10–12 inches |
| Wolves | 18 inch snare loop | 10–12 inches |
Triggering and Function
When the animal passes through:
-
Loop expands around the head or body
-
Wire pulls the lock
-
Lock hits compression point
-
Lock jams
-
Loop tightens instantly
-
Animal’s movement tightens it further
Your job is simply making sure the lock:
-
Slides smoothly
-
Grabs firmly
-
Doesn’t deform under tension
How to Improvise Snare Locks in the Field
If you lose or break your snare locks, you can improvise several types.
1. Can Tab Lock
Cut and fold a soda can tab into a friction channel.
2. Keyring Lock
Use a small metal ring and pinch one side to make a friction angle.
3. Penny Lock
Drill a small hole on opposing ends of a penny
Bend in the center
5. Knotted Cordage Lock
Create a toggle and wrap the wire around it.
Good temporary option.
Common Beginner Mistakes
-
Lock angle too tight (won’t slide)
-
Lock angle too loose (won’t grip)
-
Loop shaped too round
-
Snare anchored poorly
-
Wire kinked or creased
-
Loop set at wrong height
-
Lock facing wrong direction
-
Overhandling the site and scaring game
All of these cost results — but are easy to fix.
Expert Snare Lock Tips
-
Always test loop travel before setting
-
Wipe wire clean to reduce scent
-
Oval loops outperform round ones
-
Keep bends smooth to prevent kinking

Use fresh wire for critical snares
-
Use bending tool and multiwrench for perfect compression angles
-
Test lock grip strength by tightening on a stick
FAQ
Q: What gauge wire works best?
A: 22–26 gauge for small game; thicker wire requires stronger locks.
Q: Can I reuse snare locks?
A: Yes, if not bent out of shape. Retune with bending tool.
Q: Should I oil the lock?
A: No — reduces friction and prevents proper gripping.
Q: Are snares legal everywhere?
A: No — check regulations before setting them.
