Free to do what you want, but I’ll rehash my comment above. My L31 had the clicking and lock rock. Not sure if it came out of box that way or if it happened after my first take down when I removed the lanyard.

Aside - I have a suspicion that quite a few of us who experienced the bad lock rock also took down our knives within the first 10 minutes of receipt.

To be clear, the clicking was so bad, I could hold the knife in a pretty standard grip, and if I choked my thumb up towards the tip, I could click the blade forward with a bit of pressure. It was not a flex, it was an audible click.

A little part of me knew this couldn’t be right. You know how these things are built. Like when you see a Sebenza that isn’t centered, you know someone pinched a washer...

So I retraced my steps, did another takedown, and tightened up every piece during reassembly. First the stand off near the lanyard hole. Completely tightened. Then both screws on the stop pin. Completely tightened. Then I slid the blade and bushing/washers into the frame - completely tightened. Zero lock rock. Zero click. A few days later with an almost obsessive amount of rechecking for lock rock, and still nothing - it is perfect.

I really can’t believe this was a matter of break in. I’ve had the knife for a week. The lock rock was complete user error in my end - I think you may find the same to be true for you. Either way, please try my suggestion and report some feedback.

Not sure if you have read the whole thread...both rileybassman1 rileybassman1 and I have tried every sort of order to re-assemble our 31’s and nada. Also, mine still has side to side play, and I’m not new at this. Haha.
Glad yours worked out for you.

I have two 31's. Both with lock flex out of the box. Yes, they have been taken apart now to remove the lanyard. But I checked them straight out of the box.

My first, about a month ago, you can barely feel it now. Rock solid side to side, and very smooth.

Second, a few days old, its there but less out of the box than my first. Rock solid side to side. Also very smooth.

I'm keeping both.

Understood. Sorry to hear that you made the effort and it did not work out for you. Hopefully you/CRK are able to get things sorted out down the road.

This Covid “house arrest” stuff has me a little cranky. I’m glad you posted in this thread...and thank you for your input and troubleshooting.
I could probably live with the lock flex if i must...but not the side/side play.
My 31 Micarta is headed to the mothership shortly...thanks again.

Hey thanks for the feedback/findings...

Yea, Sharp mentioned it, but he and I have tried just about everything on these...

Here's a quick some up from the last 2 weeks for me on this thread:

Came with rock new and off center and poor action.

Cleaning and lubing and assembling, basically with your instructions, provides the best action... But has lock rock - and pretty substantially for what a sebenza should have... And there is a tiny hint of side to side... Not as bad as Sharp's copy... But still it's there when assembling in this manner.

If I assemble and tighten the pivot down prior to the bushing screws, I can get the action crazy tight... Like others have reported... Like have to open like a slip joint. If I do a careful hybrid assembly between the pivot and bushing screws, I can get the action to be side to side play free, decent action, but not thumb flickable. Centering is good right now, but very touchy depending on what is tightened when.

I've had it apart probably a dozen times and this is as good as I can get it... And I have audible clicks (there's a vid a few pages back)

From seeing other reports here, the pj versions seem to be better for some reason... My current thought is that since the inlay versions still have a locator hole under the clip, perhaps the fact that it's a similar cut to the 21 but doesn't have the larger, stickier, surface area of the titanium lock bar, that it causes more up and down lock bar movement then the pj versions.

Idk what to try next... I'm happy you and others have a good working version... Once CRK opens I may send it in - I'm just annoyed they are claiming that any movement is normal and acceptable... I have several $200 benchmades and zts that lock up more solid then this... for $550 there should be no "acceptable movement".

I'll post back comparisons once I have the same version in a 21... Idk if it will work or not, but I'm curious to try and put the 31 front scale on the 21 and see if I can make a franken 21 lol.

Best wishes!

Looking forward to seeing what the future holds for this model. I was going to hold out for a 31 with inlays. Now I may be keeping an eye out for a 21 again instead. Never thought I would see a thread like this on the legendary Sebenza. The fact that so many knives have made it out with not only lock flex, but side to side play, leaves me with a big chance to never risk my money with a 31; even when they do fix the situation. To top things of, a Sebenza should be a, "tighten all 3 screws and the action is perfect". Now there's instances of needing finesse with assembly. Rough stuff.

I wonder what the employees on the assembly/final tuning stage in house where thinking during the change. A lot of the same individuals had to have been experienced with the 21 as it passed quality control. These same issues would never have been acceptable on a finished 21, not even close.

I'm actually considering buying a back up 21 now before they start drying up..

I just did...

It's interesting to me as I've been thinking about it ... In a crowded market where other companies have caught up/surpassed CRK with regard to especially materials - and in some cases workmanship, their biggest selling point IMO was simple, consistent, rock solid knives... 2 of those 3 are potentially compromised with many of these 31s... I don't know how long they can ask the prices they do and keep selling based off of name alone.

That is not meant to be a dis at all... I just feel like watching/reading in recent years it seems like the price point is already difficult to swallow for some with the given materials. S45vn will help with that I think... I paid $25 more for my LNIB box shirogorov then I did for my 31 inlaid... Just something I have been pondering. I would hate for them to take a hit because of this.

I don’t understand the side to side play thing at all. I can take the pivot screw completely out of my 21 and the lock up is still bank vault tight. I wonder if the pivot bushing isn’t the right size on these 31’s.

It is possible, but seems like they would just use the 21's which would be the same.

Maybe the new fitted stop pin? 0.0005" too wide?

Well I heard back today after sending a video of the clicking lock rock... their response was that this was "totally normal" :-(

Guess I'll wait to see if anyone has any luck getting theirs looked at/worked on...

I cannot understand this for the life of me. How is this normal? And how are they, a company who prides themselves on precision machining, ok with his!

What?? Wow.

I couldn’t agree more. Doesn’t make any sense.

The reason why so many people buy a CRK is to step up into the next level of knife ownership. I always took pride in owning one because of the craftsmanship and very high attention to detail that went into every one I have ever owned. I received a large inkosi back in 2016 that came with a bunt tip and horrible grind. They were very quick to recognize the issue and make sure the knife was corrected and returned to me in perfect working order. I am just flabbergasted by the response that some of you have gotten from them. “It’s normal”. I’m sorry....not on a crk it’s not. At least for me.

I caved tonight. Bought a 21 brand new with inlays. I’m over it. Better safe than sorry.

I had some big goals coming up this year and was going to wait for the right time and get a 31. No longer going down that route.

I'm trying really hard to justify buying a Sebenza 31/21. Do I want a 600€ Sebenza 31 that has totally normal blade play/lock rock or 600€ Sebenza 21 that can't have blade replaced if needed.

What do we get with that price if not high quality (tolerance levels) and service?

It really is a hard and weird pill to swallow. I hate to admit this but after reading through this thread and seeing what has been happening with the new 31, I am getting a little turned off by crk. I really hate to even say that. I honestly never thought I would say this. I love/loved every one I have owned. And currently only own a small pj21. Should I use it, or just keep it in the safe? If there will be no blades or parts availability in the future, I do not want to risk damaging it to the point where it is unable to be repaired by the mother ship. When I use my knives, like many of you, I use them for everything. So there’s always that risk. I don’t know. I’m just rambling at this point.
I’ve even thought about picking up another inkosi but now I am a little disgusted with all this. Call me crazy, say I’m jumping the gun.....maybe. I’m sorry, I am just a little bothered by this and cannot seem to explain.
