What Size Korda Krimps Should You Use? A Quick Guide for Carp Rigs

When it comes to tying super neat, strong, and reliable rigs, Korda Krimps are a decent alternative. But with different sizes available, choosing the right Krimp size for your hooklink material can feel a bit confusing—especially if you’re new to the method. Use the wrong one, and you risk a weak connection or damaged line. Use the right one, and you’ve got a clean, bulletproof rig.

Let’s break it down.


:toolbox: What Are Korda Krimps?

Korda Krimps are small metal tubes used in conjunction with the Korda Krimp Tool to create ultra-strong, tidy loops and attachments in your rigs. They’re perfect for stiff materials that are tricky to knot, such as Boom, Mouth Trap, or other fluorocarbon hooklinks.


:straight_ruler: Krimp Sizes Explained

Korda Krimps come in three sizes:

  • Small (0.6mm)
  • Medium (0.7mm)
  • Large (0.9mm)

Each size is designed for a specific range of hooklink diameters. Here’s a simple breakdown:

Krimp Size Suitable Line Diameter (mm) Commonly Used With
Small (0.6mm) ~0.43–0.55mm Mouth Trap (15lb), Boom (15lb)
Medium (0.7mm) ~0.55–0.65mm Boom (20lb), stiff coated braids
Large (0.9mm) ~0.65–0.75mm Boom (25lb+), heavy mono

:light_bulb: Pro Tip: The Krimp should fit snugly over the line but slide on without too much force. If it’s loose or too tight, try the next size up or down.


:wrench: How to Use Krimps (Properly!)

  1. Cut your hooklink to length.
  2. Slide a Krimp onto the line.
  3. Create a loop or rig end and thread the tag end back through the Krimp.
  4. Position it carefully—don’t pinch the loop too tightly.
  5. Use the Korda Krimp Tool to press down with even pressure.
  6. Test the rig’s strength before fishing with it.

:warning: Common Mistakes to Avoid

  • Using the wrong Krimp size: Too small, and it crushes the line; too large, and it slips.
  • Over-crimping: This can weaken the line.
  • Not testing: Always give your rig a firm pull after crimping to make sure it’s secure.

:bullseye: Final Word

The right size Korda Krimp depends entirely on the diameter of your hooklink material, not just the breaking strain. When in doubt, check the packaging on your hooklink or experiment with a few test crimps. Once you dial in the perfect match, you’ll wonder how you ever rigged without them.
