Sebenza 31 Lock Rock?!

Status
Not open for further replies.
I would like to see how much rock/flex/whatever a 31 has after the ceramic ball has really worn into the lockface and has more surface contact compared to out of the box. Anyone want to volunteer to open and close a 31 a few thousand times and post results?

Here is the response I received from CRK:

"We are aware of the concern from customers but there are no plans to change the design. Lock rock, or vertical blade play, is when a lock begins to move vertically. Unsafe vertical play happens when a lockbar isn't fully engaging and there's a little space between the end of the lockbar and the tang of the blade. This isn't the case with the Sebenza 31.

When applying force to the spine of the Sebenza 31's blade, you will feel some vertical movement. Rest assured, your lock-up is secure. This movement is the lockbar flexing in response to pressure, though the ceramic ball, acting as a fulcrum, will maintain its position against the blade tang. It is very much a sound lock and when put to the test, proves stronger than the heat treated lock on the Sebenza 21. All of our models with ceramic ball interfaces have varying degrees of lock flex so this is not abnormal, though the Sebenza 31 seems to be under extra scrutiny as it is the newest.
All that being said, we do take customer feedback seriously and appreciate you relaying your concerns. Please let me know if you have any questions."

Welcome to the new generation of CRK...”forget rock solid knives. Random amounts of up and down play for a stronger lock that will hold your blade securely in place when using it in the wrong direction, is our new motto!”

At least my Sebenza 21 lock is rock solid enough for me,even if CRK said:

right?!?!?

it’s ok to have varying amounts of play even within the 31 line??

if everyone was consistent then I could get behind this. Maybe I’m in the minority here but come on.....

$600 for a knife that may or may not have some degree of flex??

it’s not an issue on other knives because it’s fairly consistent and minor which is ok.

Why use a knife in the wrong direction? :confused:

Your posts in this thread are offensive...you came into this thread with absolutely no new information, and nothing helpful, and just started swinging it around.
Now you somehow think you were right all along.
Tell me how to stop the up and down play...actually don’t bother. Now I realize what the ignore option is for.
 
So who is gonna put this to a test to see what fails or doesnt? Stick the blade deep into something and see if anything fails. I dont think it will

come on, show some balls. You could be the 1st with a video stabbing it through a car door. Blood score extra points :)
Or has some genius already done it?

Thanks for posting their response. CRK has went from aerospace machining tolerances to being OK if their new 31 has so much lock flex it makes a clicking noise. None of my other CRK knives even come close to doing this. Great stance for CRK to take while other companies where catching up to them in manufacturing, now those companies will exceed them. Wow, well that makes it easy to spend my money elsewhere. Way too much inconsistency for me to drop cash on a 31 now.

He mentioned how easy it is to break the lock on a 21, and the ceramic ball interface is a much stronger lock.

Is there any truth to his claim or is CRK now embracing the fine art of construing alternative facts?! I hear that's all the rage in this day and age.

In my little world I've had both a 25 and a Inkosi lock fail, but never a Sebenza. Seems to me that the ceramic ball is somewhat prone to slip off the blades lock face, and while I would surmise that the indention from heavy use formed by the ceramic ball on the S35VN lock face would counteract this slipping, I have reasons to assume that lock bar flexing does nothing but counteract strong locking even if the ceramic ball comes to rest in a very deep indention.

I agree.

I don't find the recent statement from CRK to be particularly illuminating. I think we all understand that the ceramic ball itself is going to be harder than the heat treated titanium lock face of the 21 lock bar, but that is not the same thing as insinuating that the entire 31 lock mechanism is stronger. I'm doubtful that is the case. The legendary CRK reputation for attention to detail seems to be slipping.

What I have heard to date would certainly keep me from buying a 31.

My first foray into this thread...

I'll reiterate what was asked, has anyone with a complaint sent theirs in to CRK?

We know that they don't have a presence in this forum as of now, so pissing and moaning in a thread they won't read about knives that haven't been sent in solves nothing. I'm a firm believer that if you have a problem with a person or organization, you speak to someone who can do something about it. Some of you have had a bad first experience with CRK and it sounds like you'll choose to not be back with them. I can respect that. They're not guaranteed a second chance. At the same time, villifying Tim or the company without giving them a chance to make things right in each of these cases is asinine. If you don't like it, send it back, send it in, or sell it. Complaining to people who have no power to solve your issue fixes nothing.

They are "supposed" to be monitoring their subforum but they don't. God knows why.

If I had a product to sell and was trying to be the best at it, I would certainly be interested in user feedback...
