ZT0770 - Is this supposed to be bent?

Here we are having a discussion about knives, and we get a crude insult thrown in which immediately diverts the discussion to the insult. A little courtesy goes a long way. A lack of courtesy could irritate a cantankerous old moderator. Don't.
 
OK. I have to take some of the heat here. First off, I don't think KnottyEagle's comment was aimed at RD. If it was aimed at anyone, it was probably aimed at me. Second, I made a tactical error by asking Thomas a question at USN regarding the 0770CF that had been posed initially by a BF member. Thomas took exception to the fact that the question had come from somebody other than a USN member. (Believe me, that won't happen again!) After Thomas expressed his concern, he proceeded to answer the product question I asked (because, as it turns out, I am a USN member) and I brought the answer back here. There was absolutely nothing in the information Thomas provided that was confidential and would lead a rational human being into believing that it shouldn't be disseminated outside of USN. But some folks took exception to what I did and that's how this thread has devolved to the point it's at now . . .

I apologize if I upset anyone's sensibilities.

My comment wasn't aimed at any specific person. It was to counter what RevDevil said about how It's hard to keep secrets when It's written on the Internet. That was the sole reason of my comment. Not to start drama with anyone, which seems to be what a couple people thought I was trying to start. If you want to keep something on the Internet a secret, shut your mouth. It's simple.

I brought it up because it was expressed by Thomas he wishes for the info shared.

I don't see how keeping your mouth shut helps anything. Your mouth doesn't do the typing, your hands do.
(being the comic relief..... Or trying)

Actually, if one wants to keep a secret, it's best not to post it on the internet at all.
Members of multiple forums will talk. They will do so on the various forums they frequent.
 
This cross-dissemination of information across independent forums reminds me of Dane Cook's introduction to a show in Las Vegas:

"...great to be back here in Vegas....you know how they say 'what happens in Vegas stays in Vegas'....? Well I have a new saying....if it happens in Vegas, and I see it....I'm f---in' telling EVERYBODY!!"

:)
 
Jeez, lighten up.
Cross forum comments are gonna happen.
Does the S in USN now stand for 'Secret'?
And i am expecting my 0770CF to arrive tomorrow. You guys sure it won't fall apart? ;)
I planned to test it de-assisted, but now I'm hesitant to mess with it.
 
It's pretty easy to take apart. It works nice assisted or not. I like it assisted better.
And my metal shield has a slight bend it in. Doesn't rub anything.

Yeah I disassembled mine and deassisted it, tried it out, couldn't get good centering and flipping without blade play so I pit it back together assisted. My metal piece also had a slight bend in it.

Not always.

I'll step away now since we're not even talking about the knife in question anymore.
 
Ok, to help al of the rumors out of the world. In a other thread I asked if the stop pin is strong enough for hard cutting and endurance. The stop pin is only 2 mm deep in the carbon fiber scale and I didn't know if it would be strong enough.

Yesterday I used the 0770cf for gathering wood for a fire in the garden with some friends. I had a large piece of really hard dried wood which I cut in large and small peices with all of my body weight behind it. I even battonned with it (really dont reccommend it!!!) The knife performed perfectly! This is a hard use knife! I even use it to cut cardboard boxes and other stuff on my job (Victorinox in the Netherlands)
I think we have to trust ZT in making great and safe knives.:D
Also the Elmax steel was still able to cut hairs of my arms afterwards. I think this proofs that it is stong enough for everyday (and maybe more) use.
 
Thanks Ruudr. It was, in fact, your question that I posed to Thomas. And again, I admit that I made a tactical error. I thought the world of knife afficiandos is a brotherhood . . . particularly when it comes to sharing product information. I didn't realize there are separate camps in our little world that require us to defend them from one another. Had I simply asked your question in the first person, Thomas would have had no reason to become miffed over its origin and none of this controversy would likely have surfaced. Mea culpa. Mea maxima culpa.

PS: Thank you for reporting the results of your wood gathering yesterday. They're very encouraging. :)

My bride of nearly fifteen years had the day off Wednesday so she accompanied me to the sharp things emporium - Mark's Outdoors - some thirty miles away, where I drooled over the 0770 and 0566 demo's. I was told they were temporarily sold out - good thing, as I was so broke that the trip to Atlanta and the BLADE Show, which starts today, was cancelled. Mrs. Stainz had Randy holding a 0770 for her - and she bought both it and a 0566 for me, presenting me with them when we got home that evening - as sort of my own 'mini-BLADE show'. She is a keeper.

Not fond of clips or assisted knives, I dissected both, storing their clips and screws and springs in their respective boxes. I thought the bend in the sheet metal was to stiffen it. I did have to hold my nose just right to align everything for re-assembly - and slowly tightening in order seemed to help. My blade was perfectly centered and much easier to deploy in the 0770CF after de-assisting it (The same was true for the 0566.). My fears of a non-lined CF side's strength/durability have faded after fiddling with the 0770CF for a day or so. For that matter, the altered 0566 is just what I wanted - a slightly smaller 0551!

Post de-assist, there was some worry re the 0770CF's remaining safely closed. I tried several KAI never-assisted models with the 0770CF and 0566 - specifically, the 1725Ti/SG2, 4001SW (TILT!), and 0551's.) - all failed the forearm slap test - the 4001SW being the worst! I've carried them, especially the 0551, a bunch of times in my pocket and never had one even start to deploy. I'd rate the de-assisted 0770CF as being safe to carry, post assist removal. Where my 0777 wasn't deemed a keeper here - it was too expensive to carry - the 0770CF is a keeper - and an EDC option... IMHO.

Any update on the 0770 CF rubbing? My flipper is rubbing the inside plate (opposite the lock bar) as well. I did take it apart and tried it de-assisted, and it was horrible so I put it back assisted and now I cannot get it centered. The problem looks to be the lock bar and detent. It is pushing so hard on the blade tang that it is causing the off centerdness and the flipper rubbing on the interior plate. Is there a trick in re-assembling I am missing? I tried swapping the pivot male and female ends and played with how I tightened them against each other. Usually I can get some adjustment by playing with the pivot, but the tip of the blade is actually rubbing the CF because it is so off center, and it doesn't respond to any pivot adjustments.
 
I took some of the bend out of the plate so it no longer rubs. But mine still has the same issues yours does, even with a large washer on both sides.

This isn't a popular opinion, but I think the milling in the CF and the slanted flimsy plate don't provide a solid, perfectly parallel, surface to back the phosphor bronze washer. That, along with the small diameter of the washer, requires the pivot to be quite tight in order to eliminate blade play and properly center the blade when closed. Therefor, the pivot resistance is high (separate from the detent resistance) and the flipping action isn't the best. All the inconsistencies in the manufacturing result in some knives rubbing and some not, some center some don't, and some flip better than others.

I bought the aluminum version and I actually like that model much better. It flips a little better unassisted, and there is no flex in the handles. I've never been much of a CF fan anyway. I much prefer the solid feel of metal handles.
 
I know this is an old thread, but doing the "hinderer" method I can get my 770 perfectly centered every single time. Assisted or not. Open the blade to 90*, back off the handle screws on one side, just enough to get them loose. Snug down the pivot so it's hard to move the blade. Now close the blade and push it over to the lock side (opposite side it favors before centering) and now tighten all of the handles screws back while still holding the blade over to the side. Now the blade should favor the side you were pushing it. Back off the pivot screw and all is well.

Yes, I've seen this method work on other knives as well. It's a way of forcing the each side of the handle to line up perfectly with the other. But since the tolerances are so loose on the backspacer holes the centering would fall out of center after a while. But the real problem, in my opinion, is there is not enough backing support for the clip side washer due to the milling of the CF for the speed safe mechanism. If the washers are not held perfectly square and parallel with a solid backing support they'll be able to rock back and forth along with the blade play. Carbon fiber is a stiff material, but it does have some flex. And when you mill out so much material where it is needed most you're going to have these issues. I considered filling the void with JB weld and sanding a perfectly flat face for the washer to mate with, in the hope that that would eliminate blade play, but I ended just selling the knife. I like the aluminum version better anyway.

It's such a fantastic design. This knife would be a grail for me if it had KVT with a DLC coated blade. I like speed safe too, but I think it's better suited on small knives like the Leek and Scallion.
 
This is an old thread, but the issue seems to be continuing at least to some degree. So I thought I'd resurrect it and see if anyone else is experiencing stop pin or other issues with their ZT 0770CF. To kick it off, here's a post from another thread that appeared on 7/9/15:

I would strongly recommend against the ZT 0770CF. I bought one for my brother in law for Christmas and it has been nothing but trouble. The pocket clip broke right off the bat, we replaced that and due to there being no liners inside the carbon fiber (I guess) the assisted opening flipper action caused the knife to bust the blade stop pin right out of the handle. He actually happened to find it on the floor board of his side by side. It's in a baggie at his house, he is slacking on sending it in.

My 0770CF is still perfect. But admittedly I don't use it that often. So has anybody else had problems with their 0770CF? Or is Leftytwogunz' experience pretty much a one-off?
