Liner lock concern

I just noticed that the liner lock is moving past the "center" of the blade. Instead of being in the center, it's almost flush with the other side of the blade. It's kind of hard to explain, but this should clear it up: the liner lock is moving too far over. Is that normal? It still passes a medium spine whack and the lockup is tight, but I'm worried that it'll go all the way over.
 
I have one Commander that is in the same shape as yours. Has been for a looooong time now. I keep waiting for the liner to jump off the edge of the blade, but it just refuses. I'mm seeing how long it goes.

If your conserned, call EKI. They can always rehab your knife
 
Like Mr. Hollister said, if you're concerned, call EKI. I personally wouldn't worry about it. Just let it be. You said that it's working fine. I've learned from experience, if you try to screw with it yourself, you'll probably screw it up :).

I don't know how many times I've done that, lol. I guess I'll let it be until it goes all the way over and touches the opposite liner, then it's time to give EKI a call.:)
 
My Commander is like that and it's only a month old. All my Emersons have been this way but as long as there's no bladeplay I'm happy with it. My CQC7 is running on about 2.5 years now and the lock is in the same position as it was when the knife was only a few weeks old.
 
All of my Emersons exposed a break-in period, in which not only the action becomes smoother and smoother, but also the liner travels somewhat further. My experience is that they travel about 1/4 to 1/3 further over the blade tang with respect to the position they had when the knife was new. So, if the liner was just flat with the left side of the blade, then it migrates to 1/3 of the tang after the break-in period. Most of my Emersons already started at about 1/4, so after break-in, they are dead center, or just slightly past center. From there, it moves further really very, very slow. I have a CQC7B which was around 1/3 when I bought it (new) and during break-in it traveled slightly past center and stays there for around 1 year now, and this knife sees quite some hard use.

When you look at the tang of the blade, then you'll notice that it is curved a little bit. The radius of that curve seems smaller than the radius the liner would make when you would bend it all the way to the right. Because of this, the more the liner travels over to the right, the slower it goes. It has to 'overcome' the curved ramp, which is only possible after excessive wear due to use of the knife.
 
My user Commander started doing that exact same thing. I guess it is somewhat expected in any liner lock, after a period of time.

Anyway, I sent it back to Emerson and had a knife that was completely redone within 3 weeks. The knife literally looks brand new. As a matter of fact it might be brand new for all I know. Anyway, Emerson certainly stands behind their product.
 
mine is doing the same thing, to the point that it will jam in after a hard opening.

I emailed the folks at emerson and i was told to send it in.
