Hey BF,

I owned a ZT 0620 and didn't like the frame lock. The geometry of the frame lock just felt off, as they had they used a different type of steel lock bar insert vs the 0560 . I felt the lock dis-engaged wayy too easy so I sold the knife. Does the ZT 0630 have the same issue? Does it disengage way too easy or have they tweak the lock geometry from the 0620?

0560 lock(look at the angle of the face and how thin the steel lockbar insert is): https://gyazo.com/36b762bf02aca0cce479bcc62d7d65eb

0620 lock(see how flat the face of the lock is and how large the steel lockbar insert is): https://gyazo.com/1793ed66586a9ef7ac3812246badbdbc

To me the the flat angle of the 0620 makes the frame lock disengage a lot easier than the 0560.

I believe the lock bar inserts are universal throughout the lines.

Are you sure you aren't referencing a 0560 or 0550 without an insert. Those could be tougher to release because of the falling on the titanium.
 
Yeah I didn't like the wimpy lock bar on my 0620 either. They may have made it that way so that the detent would be lighter and allow for a smooth waved open.

Is this the same 620 you abused by prying, botoning, and breaking the tip of? Because any tool you use incorrectly will disappoint....

Just got the 0630cf, don't know what your referring to as whimpy :confused:

Your hand keeps the lock bar from moving, that's the point of a framelock. .. the user helps secure the lock.

Perhaps the whimpy part isn't the knife?
 
And I remember your thread where you broke the tip :rolleyes:

Just like when people beat a knife with a steel hammer and then are clueless as to why it failed.

Common sense isn't all that common anymore.
 
I used the term wimpy to describe the tension on the lock bar. It was a light spring and a light detent which I speculated was purposeful. I prefer a strongly sprung lockbar and strong detent. By contrast, my ZT0562CF has a strongly sprung lockbar and a super (almost too) strong detent.

Personal preference I guess. Different stokes and all.

Luckily many many knives to choose from.
 
Flippers likely have stronger detent for them to... flip lol

Exactly, that was my point. I'm not sure if the OP was complaining about something else.
With my 0620 I felt that the detent was too weak. The knife waved open well but I was afraid that knife could open in my pocket. I could easily shake out the blade.

Gotchya, yea a while back he complained about the zt0620 when he beat the ever loving fecal matter out of it and broke the tip. So no sympathy from me.

I'm all for hard using your tools, just know the limits and realize if you push it and it fails... don't blame the knife.
 
I recently acquired a 0620CF and don't see a problem with it. I'm not a big fan of frame locks in general but the detent seems good. Not impossible to flick open with the plate which I find a bit awkward compared to most studs or holes. And I certainly can't shake it open though I haven't tried to wrist flick or whip the snot out of it which can open most knives if done hard enough. Definitely not worried about it opening in pocket.

The lock bar tension isn't the hardest I've encountered but takes a few lbs of pressure to move and the last little bit to clear the blade tang takes a good bit of pressure and feels good IMO. There is no lock stick with the insert and the lock bar immediately starts moving and doesn't have an initial stiction that has to be overcome like some frame locks have.

Again, not a big fan of frame locks though I've had my share, and I'm happy with my particular knife and see no problem with it. Might even get a 0630 to go with it eventually.

The OP is inquiring about a knife he abused and wondering if a similar model will be the same. The problem is, he is inquiring about the nature of the 620 after he abused it and it failed. Do notice he left this important bit of information out of the OP and rather claims the 620 has an "issue" and is wondering is the 630 line has the same issue. It is impossible for us to tell him if his abused 620 will compare to a non-abused 630. It is also strange that someone who was so very very disappointed with a knife would be considering essentially the same knife with a different blade shape.

Just for reference so we all understand what is going on here:

So prying, batoning, and breaking the tip all make a lock bar less sprung? Hmmmmmmmmmmm....

At what point did this discussion warrant thinly veiled ad hominem attacks? It doesn't even make sense lol. If he was the wimpy one, wouldn't he be complaining about a too strongly sprung lock bar? :confused:

You seem to discuss other peoples post often, I saw you doing the same thing to marcinek, don't like my post report it. Otherwise come over to whine and cheese so I can say what I would really like to say :) If you don't want to drop by I understand.

Often eh? Besides Marcinek who else? Isn't y'all's melt down thread just y'all... discussing other peoples' posts? :)

Still waiting for clarification on the whimpy comment.

The whimpy comment was in reference to gideons lock failure during his batoning. Perhaps if his hand held the framelock more securely (or at all) it wouldn't fail. Any other questions?

Have you posted a single thing in this thread about a 0620?:confused: Or are you just here to discuss my posts? You are not a mod... are you? Then please come to the place where "we" discuss posts. :)

Otherwise contribute something to the thread other than commenting on my posts, or don't. Then perhaps a real mod will drop by and remind us that discussing each other isn't a great choice. Care to continue?
