Did a little prying today with my zt 0562cf and the lock failed.

[precisionshootist]

Is it me or am I getting a sense that many of us are in denial of the obvious? IMO, the issue for the OPs situation was not the quality of the ZT knife, it was not the heavy duty build of the knife and it certainly wasn't that he used his knife inappropriately. In fact the OP's employment of his knife is EXACTLY why we carry a heavy duty "hard use" folder. This type of folder is for when the unexpected situation comes up and you DON'T have a prybar or screwdriver or a hatchet, a hammer or a heavy fixed blade knife. So what is the problem? IMO, the problem is that frame and liner locks are not nearly as strong as we once thought and many still believe. Bottom line, heavy frame locks and liner locks may look strong but that's where it ends. No matter what the quality level, this design is very week. I would go as far to say this is a flawed design. They are unreliable and easily damaged by anything even approaching hard use. By comparison, a $60 Cold Steel Rajah 3 with TriAd lock would have done this pry job and not even flinched.

The lock failed to lock the blade, but the lock didn't break. What is the "weak" part you're talking about?

Whenever I research complaints about locks breaking, it is usually a back lock. Frame locks and liner locks can get damaged and wedge the knife open - but isn't that a success story? How often do they go the other way and release the blade?

A lock can fail to lock, can break all together, or go out of spec (bend) but hold. The first two are definitely the worst.

The issue isn't that frame locks aren't as strong as many of us thought/still believe. The issue is that by design and definition a frame lock is horrible beyond words for the situation posed by the OP. We're talking the kind of precision where being off by a few millimeters is the difference between solid lockup and failure of the mechanism, how does it not make perfect sense that the lock would develop issues. Is it premature given the described force and such? Maybe. But we're talking about something that, by default, is weak in that way. We may as well be discussing why they don't make lightbulbs thicker to avoid breaking when dropped.

It has never made sense to me that most so called "overbuilt" folders are liner or frame locks. How can something be overbuilt and hard use but incorporate such weak locking mechanisms?

Some of the replies on this thread are laughable. Seriously? A little light prying WITH A ZT and everyone is up in arms. I thought these were tools no? "Hey bro don't set my hammer down on concrete you could scratch it!" I feel bad for y'all's knives, probably have never seen an honest days work.

Nothing was ever aimed at you. Your comment on the relevance of knife purpose was suitable for quoting, but I know nothing of what knives you own, and don't have a reason to. I was commenting on one particular trend in purchasing, the 'overbuilt' knife that doesn't work quite as well as a knife, which often is not used as a knife.


Fanboy much?

Being a fan of a brand is not against the forum rules.

Next stupid comment?

I've thoroughly enjoyed it.

Dear OP, what you're gonna' want to do is go pick up a Benchmade 940.


Seriously though, I want to try out one of these ZT knives, but I haven't found anything I like. I hate flippers and frame locks, too. Lol.

 

[mqqn]

Not sure how it was trolling - I was responding to the other person's post about how ZT markets their knives and I pulled up a quote from the company's website to make a point that they are actually marketed as overbuilt items for hard use. I brought this up because Krissing did so in the first place, not because I was trying to be rude.

You really believe that? You come into a thread where some jamoke has reportedly ruined a knife by using it to pry apart a pallet (or boards that are stapled together - does not matter) and take the time to go to the ZT web site, copy some marketing text, past it here and then add your snarky comment about hard use knives should be able to do occasional prying, not just "slicing thin paper".

You are here to keep the ball in the air, just like several others in this thread.

Do you own ZT knives, or are you just here for the argument, like some of the other trolls in this thread? What kind of knives to you like?

If your comments are just aimed at pissing people off then you are trolling no matter if you intended to be rude.

If you are going to say your contribution to this thread is to show that ZT knives are not made for cutting and can't cut things let's see your demonstration of your facts.

Did you even read what light prying was, or just scanning the headlines for something to add your special brand of intelligence?

The op pried a sheet of particle board (go look up MSB if you and your hard working knives don't know what that is) that was "stapled" to a 2x4 stud - sounds like he was doing "light" demolition work.

Also, did you or any of the other ZT bashing trolls in this thread happen to note that the OP was able to fix his knife by tightening the screws? Did you?

No, I didn't think so.

Yeah, feed all the trolls. That should certainly help the situation. :thumbup:

Wow, I guess everyone seems like a troll if you willingly interpret anything someone says to be an attack on your favorite brand.

I was replying to Krissig's comments about how a knife isn't built to do things other than cut and his thoughts that criticism of a knife isn't valid if the issues in question arose when a knife is doing anything other than cutting. My comments are only in response to his comments. I am not making a generalization about ZT knives.

 

[BenchCo Spydermade]

Wow, us knife nuts sure do sweat the details lol! IMO, most knives will work for most edc tasks. For example, not much is going to outslice an opinel or ffg apydie. However, when I carry my tanto kizer, while it may not slice as well as others, it still serves me very well. Only it does crack my apple when I cut it...

With prying I really don't get it. Even overbuilt knives come to a point at the tip. Thus, no matter how thick the knifestock is, the tip, the part you pry with, will be vulnerable. That thick stock would probably not make as much a dif as people think in prying because of that. But I don't get mad, its his knife, his money. Why do people care so much? Easy come easy go, Galileo, Scaramouche, can you do the fandango? Yes, you can!

How did my post extolling the capability of a ZT knife to handle the OP's task through mockery of its critics equate to me being a "ZT bashing troll"? It seems you're the one scanning headlines; did you read my post? Did you?

 

[BenchCo Spydermade]

Oh yeah, a lot of people are talking about "light prying". Let's remember that prying takes leverage to use a light pressure on one end to make much more pressure.on the prying end, the tip,.which is the thinnest part of ANY knife. This is why even heavy duty knives don't include prying in their job description. In an emergency, you do what you gotta.do, but if there are ANY other options, why use a 200$ knife for the task. I'd leave for an hour to get a crow bar before resorting to that. Anyway, glad your knifes OK.

With some blade styles in some situations, you can insert the blade part way in between the immovable object and the object to be pried off, then twist the knife so that the spine is the part of the blade doing the prying. This still puts stress on the tip but it's not like the very tip is doing the prying.
