I have a CRK with lock rock.

I've had more CR's than I care to count and have never seen that.

May I asked what type of duty that knife has seen?
 
How about a little more info. The lock face angle looks wrong and for a hard use knife it looks like new.:confused:
 
Also that's not lock rock. That's what appears to be a worn out lock on an old classic Sebenza.

So send it on in under warranty and let us know what Chris says about.

I mainly used it for cutting a lot of stuff that required a lot of downward pressure. The knife is about seven years old The scales have been re blasted, that's why it looks new.
 
Question...? How much has it been used? The thumb stud is still mostly blue and I can't see too many scratches /scuffs on the handles. But that is defiantly not the norm for a sebenza.
 
That's not lock rock. That's replace the lock bar. Did it just happen? It had to be noticeable over time. Just send it in and it will be good as new.
 
Ha I see I commented on that video. I don't see how that could happen under normal use, I think we are missing some info.
 
Send it in to CRK for evaluation. That certainly isn't right; however, it most certainly didn't happen overnight--surely you noticed play developing a long time ago. They are mechanical instruments subject to wear and tear; they need periodic maintenance; you blasted the handles and sharpened it so only was receiving SOME care and maintenance. It would have been a good idea to send it in for warranty work before you let it get this bad.

You mentioned you were a dealer--is this your personal knife you have had in your possession since new? Or, is this a customer knife that has recently been returned for you? My questions are pointed to the fact that the last individual in recent memory who started a similar discussion had bought a Sebenza used and refused to believe CRK when they told him the previous owner had abused the knife and caused his similar issues.

Please provide more details. Also, it would be interesting to see the knife torn down so we can have a look at the internals, lock face, blade tang, etc.
 
The blade was swapped. This is what happens when people swap blades. I have tried different blades to see how the fit over the years. You end up with one of 3 things. One that the lockbar will not even engage, one that fits decently, and one that has lock rock. This is the one that has lock rock obviously. I have had over 50 sebenzas, so I am well versed in them.
 
This is what happens when people decide to make youtube vids and post on forums, instead of contacting the manufacturer or reseller in the first place, as they should always do.
It leaves everyone reading to speculate. With poor explanation in the video and 0% information given in the thread, it does CRK a disservice, IMHO.

qft..
 
Hmmm.. If someone other than crk blasted it I wonder if they blasted the lock bar on the lockup area?
 
I don't see how that happened under normal use, but as somebody above says, that appears to be a blade swap, or other
modifications were made. Even if not, what in the world is to be gained by putting that in YT and on here without having talked to the maker first? I don't see how some of these makers haven't lost their minds, yet. There are constantly threads and YT videos popping up about some kind of "problem" with a maker's knife, and in almost every case they put it on the internet for the world to see before contacting the maker first to give him a chance to see what's going on. And in almost every case there's some vital information that the person conveniently "forgot" to tell everybody that's usually a real game changer. I wish everybody could see what it feels like to make your living with your hands, and have people, usually anonymously on the Interwebz, assail your product without having the decency to let you address the problem, first.
 
I watched the video.
This is no lock rock, this is a very loose blade.
The lockbar has been bended over to a degree where it can only be disengaged with a lot of force, hence the great force needed to open en close.
At 3.03 you can see clearly that the lockbar looks deformed like being hammered on the spine of the blade, maybe a swapped blade like nyefmaker said.
This knife did not leave the CRK plant in this state, no, just impossible.

I peened the lockbar of my 1999 BG42 large regular lefthanded Sebenza to bring it back from 100% to 45% lockpercentage. It has no play in any direction, locks solid and very good and it is not sticky anymore.
It took quite some force hammering with a 1kg (2.2 lbs) hammer and a 6mm (just under 1/4") nail punch to get this effect. The titanium is hard and does not deform easily.
This technique is not recommended and no one should try this, it voids the warranty. Just didn't want to have the risk of loosing it in the mail, I live 8.160km (5.070miles) from Boise, Idaho. Straight line on Google Earth.

The knife in the video has either been misused, or the titanium is to soft, or the blade is swapped with the badly hammered original blade?
I would not like to see Chris Reeve's face when he gets this knife in his hands.
Sad to see a masterpiece like the Sebenza in a state like this.

Math.
 
Too many questions to answer them all right now. Here are a few though. Its always been my knife not a customers, I never did a blade swap, the blasting was done by Reeve, the lockbar slowly went over, once it hit about half way the lock started moving over faster. I don't know if a couple posters were kidding, about it's not lock rock. If I shake the knife up and down, it is rock lock. You can hear it undeniably. I think madmath is closest. It feels like the ti is soft compared to others I have had. And no, I never hammered the spine with anything. Have to go for now. Will check back in a couple days. Have a happy and safe 4th!

I emailed Chris about this thread, so I expect a response probably next week.
I have decided to send it back in.
 
I should be out the door right now, but looking harder at the lockbar, its clearly indented. Not sure if it is soft or not, but it seems that way?
