ZT 0630 lock vs 0620?

[kniferbro]

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? 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?

I asked you a question lol. No need to have a melt down!!!

Didn't think so.


Back on topic, I need to pick up another blade from you Scott, perhaps another 0630cf with a different anodizing for variety! And gideon, use the knife correctly and the 0620 or 0630 cf or not cf will be a great blade. I have been happy with mine for a long while now without issue.

Okay, yes I beat the shit out of that knife. After I realized how easy the lock would disengage and wanted to test it. But, that is not what I mean. The knife would also fail an extremely light spine whack. What I meant is, not the detent in deploying. Now to the person who said all the lockbars on the 0560 and 0620 aren't. When you look at the at the faces of the lock, the zt 0560 is more angled and frankly seems to not disengage easily under pressure. But has still doesn't have lock stick.

This is the steel lockbar insert in the 0560(see how insert is small): https://gyazo.com/36b762bf02aca0cce479bcc62d7d65eb

So are you changing your story? Above you say that you noticed the lock slip and then tested it but in the original quote about this knife below you only notice the lock slip after you broke the tip off, pryed with it, and batoned. It is important when discussing such things to get the facts correct or how are we to take you seriously?

Hey BladeForums,

So, I wanted to test out my BM Griptilian 553 (tanto) because of the reputation of the axis lock. I did some cutting, light prying, heavy prying, light batoning and heavy batoning. It passed with flying colours and I was kinda impressed. It was hard wood (I think oak). So I brought out my ZT 0620 because I loved it and thought if the BM Griptilian could handle it easily, I bet my ZT 0620 could. Then after some medium prying... the tip snapped off and I was like what the ****... SO then I did some light batoning it did good, medium batoning it failed. I gave it some more tries and it failed. I didn't hold hard into the lock bar, but it kept just slipping over it looked like. As when I closed it, and engaged the lock again it felt rock solid (hardly any movement, if any at all) but yet, kept disengaging which is extremely disappointing not to mention how easy it was to break the tip on some medium prying and how a knife half as expensive (griptilian) took way more and is still in like perfect shape. I know these aren't everyday tasks, but some light prying and maybe some batoning may be used in a "hard use military knife" as ZT claims there knives are so I thought I would try it. Here are some pictures.

You will also noticed that I removed you bad language in both posts, something you have been warned about before. This is the family friendly part of the forum

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

Would it being less sprung have to to with the bigger problem of the lock slipping? Or did he damage the knife causing it to slip after he abused it and the less sprung lock bar has nothing to do with anything? He's got multiple threads revolving around this subject (4) so why consider buying the exact same knife again? Hmmmmmmmmmmmm

 

[Scurvy092]

If you baton with a folder while it's locked, you don't get to complain about the lock slipping afterwards...

I have no doubts batoning could deform the lockface and cause slippage. I was under the assumption that the OP was referring to the lightly sprung lock bars on the ZT/Emerson collabs that many have cited. I don't see how the mentioned abuse could have defeated the over travel stop and caused the "lazy" feeling in the lock bar.

It's rather complicated, you see, framelock knives have a cut out that allows them to "spring " smashing the top of the blade will bend the relief out of spec. Take a second and think on it. ..you'll get it.

So the smashing on top of the blade would cause the lock bar cut out to permanently deflect enough to cause a measurable change in lock bar tension? Do you have any data to back this up? Even anecdotes would be pretty revealing.

Beating on the knife will totally mess it up. I don't think beating on the knife would change the lock bar tension though.

OP should contact warranty services if he thinks somethings wrong.

And can you guys not act like childeren for once? Does every thread have to devolve in to snide remarks and bickering about who said what?

Actually nevermind. Its funny

That was mentioned by many 3 threads ago. The OP has also since tried to sell the knife without disclosing the abuse and the lock issue. Not sure if it sold and he disclosed the issue privately. Though he did not disclose the abuse here until it was pointed out. He may not still have the knife.

 

[blades&wrenches]

I had a 0630 for a while and didnt have any issues. I felt the lockbar had a good balance between adequate tension for confident lockup while still being able to use the thumb disc comfortably and efficiently. I felt like the lockbar tension was lighter on my 0550. I never batoned or pried heavily with them though.

 

[DapperDan]

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.

I own the 0620CF,562CF and the 0630CF all with M390. The tension of the lock bar are the same on mine. The detent on my 0630 and 0562 are very strong. Like you say; almost too strong. On a side note when I got my 0630 I was kind of disappointed that it was exactly the same as the 0620 just a different blade shape. I bet I could swap out the blades and they would work just fine.

 

[toker]

The ZT620 and ZT630 should be virtually identical apart from the blade shape.

That being said, I've never had an issue with my ZT620 and the lockbar has a good amount of tension. If you can shake the knife loose from closed position, tighten the pivot.
