Lock rock

[Lucabrasi]

So I have now discovered my Chef has lock rock. Has always had super late lock up but had not noticed the rocking until today. I also realized I can push the lockbar over 100 percent.

Is there anything I can do about this? I have been considering carbidizing the lock face, just haven’t gotten the tools yet. Is it possible to layer on enough carbide to eliminate or reduce the rock? Or is the added layer too thin to impact this. The rock is audible, not really all that slight.

I love this knife, had been my favorite Spyderco but this was an unwelcome discovery.

Exchange it or make a warranty claim.

No framelock should have 100 percent lockup/ lock rock.

You mean "back lock", right?

OP said chef, as in spydiechef.

Man, I'm silly... :o
Did not read properly, thought he meant the Chief, not the Chef...

I’ve had it since December is that a viable option?

[Lucabrasi]

And right, I have multiple other frame locks that don’t move 1 iota. I guess the late lockup I had read that was common enough to not be upset about but didn’t realize it had this much mobility while the lock is engaged. If I were a betting man I’d say it has always been this way, I just hadn’t checked previously to know.

I would go to customer service with that. No frame lock should have that issue so soon.

Yes that's what the warranty if for. I agree with the others. The lock up should never be that late

[Lucabrasi]

Ok, I emailed Spyderco about it including pics and a video demonstrating the lock rock. I’ve never had to do any warranty work before, besides asking for a new screw that I stripped, which was generously and readily handled. So wasn’t sure the process.

Also had taken interest in the idea of carbidizing lock faces so was hoping somebody would tell me that would fix it. But seems like going the warranty route is smarter. Thank you for your input.

Hi, Lucabrasi:
I'm sorry to hear about the issues with your Spydiechef. W&R will likely need you to send your knife in for evaluation. It might save you some time to send it in now and let them evaluate it. You'll find all of the information you need here, https://www.spyderco.com/service-suppor ... ty-repair/. Please be sure to include the W&R form with your knife. Our W&R team will do their best to assist you.

[Lucabrasi]

Thank you, I will send it out soon.

The Spydiechef has a very thin lock bar, and the lock face is not perpendicular to the lock bar itself. The combination of the two allows the lock bar to flex at the frame, which leads to lock rock and late lockup on these knives. Next time you open your knife, watch the gap between the lock and the frame.. You will see what I mean. The lock bar actually flexes away from the frame. I think a small change in the geometry of the lock face would fix this problem.

Well just got word from Spyderco that this is not a problem. So when I get it back I’ll go back to the carbidizing the lock face plan and try to layer it on thick.

They said lock rock is not a problem?? Did they give any further explanation?

[JonLeBlanc]

May I ask what exactly lock rock is?

Vertical blade play, as opposed to much more common lateral blade play.

A bit of lateral blade play is no big deal, in fact a lot of people will deliberately loosen their pivots to the point of very slight lateral play in order to get the best possible opening/closing action.

Vertical blade play, or lock rock, is considered a VERY big deal.

Oh ok, yeah I can see how both would be a problem, but I definitely wouldn't want vertical play.

With regular lateral play you can usually fix it by just tightening the pivot, but unless it’s really major it won’t actually cause any issues that I’m aware of. Honestly most knives will eventually develop it just from the pivot loosening over time, especially if you’re rough with them.

They said that it is within spec and doesn’t qualify as a warranty issue for repair or replacement. Said a small about of “flex” can be expected. Can’t say I’m satisfied with this response relative to a $230 dollar knife when a 90 dollar Kershaw can nail it. But what am I supposed to do? I didn’t want to send it in, was convinced here this was an obvious warranty issue and then told nothing to see here when I did. So I guess I’ll experiment with carbidizing as I originally planned.

I have a ten second video that demonstrates the audible rock to show I’m not making this up, but can’t figure out how to embed. So I guess my word will have to do.
