Large Insingo 21 alignment

So I have mentioned this a couple times about my Insingo that I've had since May this year, and I sent it back already to fix the problem.

The problem is that my sebenza falls out of alignment fairly quickly. When I first received the knife I noticed right away that the blade was uncentered and that the detent was ridiculously hard. I disassembled the knife and reassembled it with no change, so I sent it back to CRK.

I received it 7 weeks later perfectly centered and buttery smooth, but after about a month it was slightly off center and the detent was harder (though not quite as hard as when it was new).

I took it apart last week to clean it, and when I reassembled it I purposely biased the blade towards the opposite side while tightening it down, and it was perfectly centered and the detent was perfectly smooth. After a week of use it is again slightly off center and the detent is stiff.

I'm wondering how to go about dealing with this situation, because I'm afraid if I send the knife back to CRK again I'll be without it for 2 months (it's my only Seb) and then they'll do whatever they did last time which was seemingly a small bandaid on a bigger problem. And while I really wish my knife was consistently damn near perfectly centered and with a flawless detent, I'm wondering if I'm SOL on this issue.

Any thoughts???

I would call CRK again and tell them just what you posted above, including your concerns.

I'm a newbie here compared to others, but I've got two large 21's and a Zaan. I use all three regularly and I've never had those problems with any of them. All contact I've had with CRK CS has been favorable and productive, with any questions/problems resolved satisfactorily.

They really are great to work with. I believe they will understand your concerns and do right by you. :thumbup:

Edit: If you can post pics of the problem, that might help.
 
Is your pivot screw or stop pin screw backing off? They should be tight (snug) against the titanium. What side does it want to favor?

ETA: Are you reassembling properly (scales together first, etc...)?

I did notice one time that he pivot screw backed off a little on its own but I tightened it down completely and it never did that again, guessing I just forgot to tighten it one time I cleaned it.

It holds secure though otherwise.

I'll give them a call! Thanks.
 
Most times I post my opinion of CRKs blade centering, I get swamped by claims that they are all perfect, and I'm somehow to blame, or need to take my knife apart (again, and again, and maybe again)

Owning 3 small 21s, 4 large 21s, a 25, and an Umnum, I would attest that CRKs do not all have perfect centering. And no, it is not a pinched washer, nor is it dirt, nor is it that I put it together wrong, they just are the same as most knives: many have perfect centering, and quite a few don't. My Insingos are the worst offenders. The blades are perfectly parallel to the slabs, but the grinds are just off enough to notice. Sure you can reef on the knife and twist it while tightening down the screws to create a temporary centering, but over time the knife will migrate back to its natural state.

I am a huge fan of CRK, and have spent thousands of dollars on their designs, which I like very much. The only reason I write this is to maybe point out that we all have very high expectations that might need to be toned down a bit when it comes to CRKs products. They are great value production knives, but are by no means all flawless, and that's OK. If the blade favours one side or the other by a millimeter, the knife is not defective, it's just not perfect, which does not diminish its usefulness or great design.
 
Ive also spent thousands of dollars on CRKs, and only one of mine was slightly off center. It was old and of indeterminate origin.

Where are you going? You stated your experience, I stated mine.

I've personally seen what kind of process the knives go through before they go in that box. As I would expect, all of mine are centered.
 
Ya this is a stupid thread I should have just called CRK from the start. Only reason I didn't is because it seems to be a rare problem and I've already sent it back for 2 months. When I decide I don't mind not having it for 2 more months I'll send it back to CRK. For the time being ill just keep using it. Thanks for the replies.

Must of been a different dude inspecting mine before they were boxed. Guess its rotten luck for me! Oh well.
 
Two of my CRK's have off centred blades after putting them back together with their blades in the closed position. So with these two I loosened off all the screws, deploy the blade then tighten all the screws down and both of them come up perfectly centred.....I'd be curious to see if others could improve their off centred blades in the same way.

Second this, although I only have one small 21, it to is slightly off center due to the grinding of the tip. Blade is perfectly centered between the slabs so I don't worry at all.
 
Only time I experienced a not centered blade was, when the pivot screw came loose.
Fixed the pivot screw with Teflon seal tape - problem solved.
Hope this helps.

PS: Please let us know how this works out.
 
The knife will not go from being centred to being off on it's own, either the pivot is backing out or "another problem" exists. While an off centre blade is very unusual it does happen, it can be down to the edge bevel, blade grind, warping or fit of the knife. All of those will be a constant though and not one that flip-flops form being there to not being there. You sent the knife to CRK and they sent it back fixed so I expect that there is "another problem" at the helm here.
 
How I would proceed is depending on the extremity of the "problem" (which we still have not see a photo of).

Given that concept, I'd suppose CRK will ask you to send it in.

Honestly I have not inspected mine since I got them (photo below). They work well, so I use them and suppose they are likely centered, but if they don't rub something during deployment, I don't care much, and just use them. (Just my 2 cents).
