Use the Korda Krimps.

I assume you've done this , are you saying one us better than the other.

I also assume that there is no trick I'm missing here, I'm crimping correctly they just snap at that pressure?

It always starts with the boom slipping in the crimp which shreds the boom material then snaps , can't understand why ?

Are you saying korda ones are better ? Have you some experience with both?

Would Whychwood pliers work with Korda crimps ?

The only way to find out which crimp works best for YOU is to test one type against the other.

here is another suggestion; crimp both ends but with a swivel in one of the loops. Then tie some reel line to the swivel and use your normal knot to fix that to something. Then pull and see what breaks first.

If the crimp goes, then you have a problem, if the mainline knot goes then the crimps are strong enough.

no you assume wrong lol I havent done it but I do have both sets

the Korda ones were a problem but then they changed the crimps by then I had lost confidence and bought the Wychwood set and for me I think they are much better I did not have any problems

in a fishing situation your mainline would probably fail long before a crimp so maybe you could test that ?

Used Wychwood and Korda crimps, both carry carp tax but are ok. But then I use Amnesia which is much cheaper and I like the bit of stretch it has.

Prefer crimps from a sea angling supplier on Ebay much cheaper and seem easier to use.

Thanks, I lost a fish the other day when the crimped boom failed , that's why I started testing it, the 25lb boom appeared to have snapped at the crimp.

When I did tests the tested hooklinks snapped the same way as mine had when I lost the fish. ie at the crimp.

Lack if confidence in them now.

Asked the question on here in case someone could see I was doing something wrong, or could suggest a solution . If that's not the case and I am crimping correctly then I'll look at a different solution.

Do you think Korda crimps would work with Whychwood pliers ?

The solution is tying a knot?

I just did a test for you.
8" of 25lb Ace Riga-mortis line, Korda 0.6 Krimp, Wychwood Crimper tool.
Loops were 15mm. Ends were unblobbed
The pull effort was sufficient to make me concerned the rig puller tools would pull apart.
No line slip whatsoever.
Next test was with a black builders bucket and water.
The loop failed at 22lb (that's the bucket filled about 3 inches from the top by way of comparison ) by the line pulling through one crimp.
Both Krimps had flared at each end as normal with the Wychwood tool which is narrower than the Korda one.

Conclusions;
A: You are Garth and I claim my £5.
B: Use a different line.
C: As I have no picture of your crimp, are you 100% sure the crimp is not getting twisted and then flattened in the jaws of the crimper ? The crimp must stay upright . With my crimping example the jaws do not meet exactly, there is still a slight gap.

I use the korda 0.6mm crimps and pliers and 25lb boom. Also, crimp using the large hole in the pliers. just make sure its in the notch properly and squeeze the pliers as hard as you can. Hand on heart not had an issue.

...That said I do use the Gemini booms now instead for convenience which are outstanding and neater.

Very tempted to tie a fig of 8 knot, but wonder hiw bulky that would be with 25lb boom, and how that would effect pulling it through weed , of which there is a lot on my lake.

Thanks for your help, I see you used korda crimps with Whychwood pliers, this obviously works for you, so may try that !

Yes crimp is correct way in pliers I've been meticulous in getting that right in case that was the issue.

Just to double check when you look at the Whychwood pliers with the 6mm hole at the top, the crimp should sit in the pliers like a figure of 8 lay on its side , or like looking down the barrels of a side by side shotgun, oo like this ?

What kind of rigs are you using the boom for? How big do you need the loop to be? I think the hook and lead will catch a lot more weed than a figure of 8 knot in the boom. You might even get away with using an overhand loop knot in such heavy material.

Drop the lead, and hope hook is inside the carps mouth so out of the way ! But yes thought of overhand knot , haven't got around to testing that yet.

I have both Korda and Wychwood crimps and pliers.
I much prefer the Wychwood tool and components .
I only used the Korda Krimp in the Wychwood tool to test for you.
The crimps need to be like 8 in the jaws, like an over under shotgun, one half of the crimp in each jaw.
Are you sure?

This action cannot be undone.

Yes, continue
