Interesting blade failure on a Sebenza...

HaHa. Well it's unlikely that wiping the blade on his pants leg CAUSED the blade to break. But accumulated stress over time could weaken the blade sufficiently for it fail with little effort. It's sort of like the straw that broke the camel's back. It's also water under the bridge as CRK apparently replaced the blade. So I guess Chris agreed that the failure was due to a material defect and did what he had to do. I would expect nothing less from CRK. :thumbup:

I don't know why, but lately, members here have been trying to throw logic out of the window and blame knife makers for anything or shout abuse. I don't get it.

The blade broke, CRK replaced it under warranty, everything is all well again... Until someone shouts "THAT IS IMPOSSIBLE!" :foot:
 
Chris Reeve said they had about a 100 blades returned broken, since they started producing Sebenza's.
You could break any blade if you wanted to...

That's not surprising given Chris's QC. The only way to reduce that further would be to x-ray every blade that leaves the shop. To the best of my knowledge, no manufacturer does that.

In the world of knifemaking, paying for someone to x-ray the steel is quite expensive. Even then, that would only rule out the few blades, here and there, that are fractured.

They should be giving each knife a full MRI!
 
Yep. That's why it's rarely done. Only time I've ever heard of it is when a blade broke and the manufacturer needed to dig deep into the cause of the failure to find out why it happened. Some defects are easier to pinpoint than others. But unless a pattern of failures has developed which is clearly not the case in this instance, it's not worth doing.

This is very true and you are not alone in noticing this. It's plain old trolling and nothing more. However, if it doesn't come to a stop some incentives will be issued to help with that. It's already tired and unoriginal. I guess it's easier to act out like a kid than formulate any sort of thoughtful commentary. Kind of like visiting the chimp area of the zoo.
 
Many years ago I HAD A 55 LB. cast iron anvil I was trying to straighten a piece of steel on. I hit it pretty hard with a 5 lb. sledge and it cracked through it and half way down it. My point any metal can break. However CRK makes some of the finest knives I have ever had the privilege of owning. If one of the two I own were to break I would still say CRK makes some of the finest knives I have ever had the privilege of owning and would not hesitate to purchase another.
 
Guess I'll open my own knife company and use depleted uranium blades.

There's one member in particular who seems to delight in trolling CRK threads that I hope gets that incentive sooner rather than later.
 
Good on CRK for replacing the blade.
Things happen and its nice to see people being taken care of.

Breaking the blade wiping from wiping it on your pants sounds unrealistic.
 
To the op: why didn't you post this thread in the CRK forum ? This didn't happen from wiping the blade on a pant leg.

How was the knife used before this happened...was it dropped on concrete or a floor. Was the knife abused, we don't know anything about

how the knife was used before the blade broke.

Negative comments about CRK as usual.
 
If you look at the blade, the fracture is very clean (as far as one can tell from the photos). If this knife was broken with brute force than there would be substantial damage at the point of fracture (deformations, chipping, etc.). Glass may give you such a clean breaking surface, but not a tough, not-too-high-HRC steel. On top of that - the pivot seems undisturbed - that would hardly be the case if brute force was involved.

If this was a HRC65 honyaki Japanese kitchen knife blade, than fracture like this could happen if the knife would be dropped on hard surface, but this is pocket knife developed and optimised for hard use. So I would suggest stop proposing that the OP made up the story.

$hit happens, OP had bad luck, CRK handled the issue honourably. CRK was not lessened in the process in any way - my own Sebenza did not become any worse. If CRK received 100 broken blades over 25 years, than they must be well under 1% failure rate (and probably under 0.1%). Respect. End of the story.
