I have a CQC7B and it doesn't seem like the liner lock is fully engaging. No lock failures but just a bit of the liner doesn't move over to contact the tang. Should all of the liner engage the tang?
All of the liner used to engage the tang until I set the tension screw with loctite and practiced opening it with a flick of the wrist several times.
Is there a quick fix?

Chad, That's a tough one. I'm trying to think what could cause that. Basically, it's the opposite of wear. Somehow, you've gained material (i.e. closed the distance).

Just to be clear, the liner on my CQC7A measures 0.050" thick. Are you saying that only a half, or 0.025", of your liner is in contact with the tang?
 
Sorry if I confused you. More than half of the liner is in contact with the tang, in fact most of the liner is in contact with the tang. It fails by just a hair's breadth of fully contacting the tang, is this normal?

I've had the same problem with several liner lock folders. I judge the reliability of the locks on my knives with the following:

1) The knife should not close when you grip the knife tightly in a fist. In other words, gripping the knife tightly should no disengage the lock.

2) You should not be able to disengage the lock by trying to force the blade closed with the lock engaged. The tang should not be able to slide on the liner, closing the blade.

If one or two of these events occur, I would deem the lock defective and send it in for work.
 
As long as most of the lock is engaging the tang, I'd think you'd be alright. Just make sure the contact area is clean and not linty or anything, and the lock should eventually make it's way across. Unless you're planning on stabbing car doors or something, in which case I'd send it in for a tweak. Everbody says Emerson customer service is great. I'd just ride it out and savor the longer-wearing lock, though. (Maybe you should listen to the others though --I have too many cuts to be giving advice.)

Great responses. Yeah, I'd say the same thing. As long as your getting a tight lock-up and no slippage, you'll have an extremely long wearing knife. Give it a while, and see how it breaks itself in. If at the end of that time it's slipping, do what the other guys and send back. Emerson Customer Service is excellent.

Note: chief dignitary had a good point. Don't get oil or grease on the tang.
