Problem with CQC-7


February 17, 2003, 08:32 PM
The liner lock on my Emerson CQC-7 fails with minimal pressure applied to the rear of the blade.

Any ideas for a quick fix?

Mine, too. I'm calling EKI this week. I'll post updates later.

I've been flamed to shreds by EKI fans for saying this, but here it is again: I've seen this happen on a lot of EKI liner locks. The lock is, obviously, not safe. I personally don't believe there is a quick fix ... I'm skeptical there's any fix at all in many cases. The problem is the geometry between the liner and blade tang. Sometimes re-grinding the liner can fix tje problem; other times, it can't.

Liner locks are extraordinarily difficult to consistently manufacture reliably. It's why I avoid that lock format completely for hard use knives. Difficult to make one reliable liner lock; very difficult to make many. Just my opinion, from trying out very many of them.

I tend to agree, Joe. Absent something like the L.A.W.K.S. system, I think I'll forego liner locks in the future.

Problem is, all my current fave knives are liner locks.

While I've never had any problems with any of my liner lock knives, I'm not much of a Emerson Production fan. Infact, over the years I've always ended up trading off my Emerson's for others that I just needed.

IMHO, the production Emersons are one of the most over rated production knives out there right now and, like Mont Blanc fountain pens, living off an marketing driven reputation.

Well, I'll go against the flow here and say the Emerson liner locks I've used were are great.
Yes a liner lock wears out after a couple years of real hard use (like I put mine through), but 2 weeks at EKI and it had brand new liners and is rock solid once again.
Send it to EKI, they'll take care of it.

Any lock can fail... all locks have their disadvantages... dont like it? Get a fixed blade. ;)

I've only owned one Emerson product, a 2000 Commander. I really tried to like that knife but ended up selling it. I just didn't like the chisel grind at all. But we're talking locks here... I was able to notice a slight flex when I tested the liner lock on it. A lot of pressure had to be used in order to get the flex, but it was there. Never had it disengage however. The only liner lock I've ever handled that seemed super strong is the one on my Spyderco Military. Now that's a solid liner lock!

I agree with Jar, EKI production knives seem over rated. Lots of hype out there, which is one reason I purchased the Commander. I just had to know what all the hoo ha was about. Now that the knife has come and gone, I still don't see where all the hype comes from.

I carried that Commander for an entire summer and when something needed to be cut, I usually fished around in my pocket (past the Commander) and grabbed my old Copenhagen Snuff Old Timer. The Wave had a neato factor, but cutting with that chisel grind was like trying to cut something with a WWII bayonet.

Just my opinion. :(

I'm not the biggest fan of the edge grind either... the blade itself is double beveled, V Ground, but the edge is a Chisel... that, in combination with being a Re-Curve, makes it hard to sharpen... buut.... if you make a little effort, and take the 15 extra minutes to get a really good edge on it, it'll cut like mad.
Or, you could take an extra hour, and a series of various grits of diamond hone, and make it a V grind like I've done with my commander. Its a lot nicer like that for work where you dont want the knife cut to pull off to one side or the other.

Emersons dont have the finest fit and finish, but the only thing I've ever noticed in that regard is that the liners arent super finished, they are a little rough. Everything else seems to me to be the fit and finish quality of Benchmade, Spyderco or others. All the new Emersons I've handled were some of the smoothest production knives I've found, to open and close. My Commander when it was new was almost smoother than the Emerson custom I had for a short-while (now there was a knife!).
I have done hideous things with my Commander, I've dug around in the dirt, I've made it cut things it shouldnt cut, I've used it as a screw-driver, to pry with, to chop with, I've used the serrations to saw through all sorts of tough materials.... I even used it to scrape tar off a tin roof one day. No wonder the liner needed a change after two years, its a wonder it didnt need it before.

I still say they are some of the toughest knives around... mine have been I know that.

If I were to buy a CQC7 I'd stick to BM. Much better customer service. EKIs service in my experience has really lagged. Thus granted that BM is a bigger company. I havea CQC7B and all its been good for is throwing at trees while I am camping. The liner lock is really bad. The pivot screws always needs to be adjusted and the tanto blade isnt all that sharp. (This is before it became a throwing knife :))
