Copper precision for stronger rigs
The Swimerz double crimp is a small but decisive component in the angler’s kit. Its compact copper form sits quietly on the bench until needed, ready to replace complex knots with clean, mechanical security.
Designed for heavy monofilament and wire lines, this tool streamlines rig assembly. It suits anglers who value accuracy and durability over speed alone, ensuring every connection holds under pressure.

MATERIALS
Why copper outperforms steel
Unlike aluminium or steel, copper resists corrosion and fracture in harsh environments. This material choice means the crimp maintains its integrity season after season, even when exposed to saltwater or abrasive conditions. The metal’s natural properties contribute to a longer service life without compromising structural strength.
DESIGN
Double barrel separation
Each leader strand occupies its own chamber within the double barrel sleeve. This separation prevents strands from overlapping, a common source of damage in single-barrel designs. By keeping lines distinct, the crimp protects against abrasion and ensures a more reliable, predictable connection between components.
IN USE
Light pressure for secure fits
Application is straightforward: slide the crimp onto the line and apply gentle, central pressure with pliers. Overtightening can crush the line, so restraint is key. The smooth bore and burr-free edges allow the line to settle into place without snagging, reducing the risk of micro-damage during assembly.
PRACTICALITY
Fifty units per carton
The pack contains fifty crimps, sufficient for multiple rig builds or a full day on the water. The packing carton measures twelve by seven by one centimetre and weighs zero point one kilograms, making it easy to store in a tackle box or vest pocket without adding significant bulk.
AT A GLANCE

Highlights Summary
- Designed for heavy monofilament and wire lines
- Made from corrosion-resistant copper
- Smoother, safer, and easier to crimp than aluminium or steel alternatives
- Double barrel sleeve prevents leader overlap and damage
- Improves rig strength and speeds up rig-making
- Available in packs of 50
Detailed Features Benefits
- Material Advantage
- Copper crimps are highly resistant to corrosion and less prone to fracture, ensuring long-lasting performance even in harsh environments.
- Ease of Use
- Copper is more easily crimped than aluminium or steel, reducing the risk of damage during rig assembly.
- Precision Engineering
- Smooth bore and burr-free edges protect lines from abrasion and ensure a secure fit.
- Double Barrel Design
- Each leader strand fits snugly in its own chamber, preventing overlap and related damage for safer, more reliable rigs.
- Stronger, More Accurate Rigs
- Crimps reduce the need for knots, resulting in stronger rigs and allowing for precise hook length adjustments to meet bait clips or impact shields.
- Efficient Rig Building
- Quicker and easier to use than tying dropper knots, saving time and improving accuracy during rig setup.
- Safe Application
- Crimps are slid onto the line and gently squeezed with crimping pliers; overtightening or improper crimping can damage the line, so only light, central pressure is needed.
