ZT 0566 - Assisted open mechanism failure

Just save your money and get the xm. Even if you buy the ZT 562cf, you will still want the xm.
 
Tax write off as well. Get the XM if that's what you really want. I'm looking forward to the 562cf though. I wouldn't dream of the XM currently but if I was a firefighter then it would be impossible to resist.
 
So I took the knife apart and removed the broken torsion bar. It was snapped in half. I cleaned out all the grease, dust etc really well. Then I re-oiled and adjusted the pivot perfectly and the blade simply flies open with ease. It's smooth and extremely fast.

Great to hear that it works good as a manual mine does also and I prefer it that way.

Edit to add ZT will send you another to have in case you want to sell the knife later.

If that happened to me, I'd be happy. Saves me the time and effort taking it out myself. But seriously, either take it out completely or I'm sure ZT will take care of you.

It only takes a couple minutes. Not the kind of project that would require scheduling time off work or anything. You'd also save about $10 in shipping costs.

I know, but some people may not be confident in voiding their warranty by taking it apart themselves.

I don't post in the "general area" often. But thought I'd say that if you are a firefighter and plan to use the XM on the job, then it's not a treat to yourself, but a tool that helps you help others.

This.

How many knives will you buy trying to fill in for the XM-18 you want so bad, just 2-3 ZT's and you'll be past the $375 the XM will cost you and if something ever happens, you need money ASAP or don't like it anymore even used you'll be able to flip it for more than your cost anyway.
 
So it's the oddest thing. I got my 0566 about a week ago and it has a really strong detent. I don't mind that at all. I took out the torsion bar within an hour but I just couldn't get the thing to fire out manually. So I put the torsion bar back in for a day (literally) before I got tired of it. Last night I took the scale off, got the torsion bar out, put the scale back on and centered it again. And BAM! This thing fires out like a dream! What caught me by surprise was that I had used it manually for a few days and it flipped horribly. All I did last night was take the torsion bar out, and all of a sudden the action is so much smoother. I didn't lube it or mess with anything else; all I know is that it flips like a champ now and that rules :thumbup:

We are not talking Benchmade here, this would not void the warranty ;) Kershaw/Kai has great customer service and takes care of its customers :thumbup:

This is getting pretty OT but benchmade isn't really that strict. They have my pretty modded 710 now and they were happy to fix it even after I disclosed all the mods. It's got non-factory stand off's (with screws from each side, not the factory style with long screws/captive nuts) and a wave notch ground in the blade and has been fully disassembeled numerous times. When I told them before sending it in they didn't express a single concern about it.
While most companies state "disassembly voids warranty" the thing they're trying to prevent is getting sent bags of parts to put back together.

Money isn't the issue for the most part. My wife and I both have excellent incomes, my problem is that I'm just super cheap. I always feel guilty whenever I get myself something. I've just always been that way. So I usually sell off a knife or two whenever I want a new one.
But after starting this thread and reading through some of the responses, I've been giving this a lot of thought. I'm gonna pull the trigger and get the XM-18. Some good points have been made such as being able to resell it for at least what I paid. And at work it would be awesome. It's a tool I would use daily so I might as well enjoy it. Currently for work I use a Spyderco Assist and it's great especially since I cut a lot of rope and seat belts etc, which is why I never spent crazy amounts on other knives cause they were always for EDC use off the job. But my Assist is simply a tool has no value to me. And it's a pain to sharpen. A really good quality plain edge would work just as well so I've decided that I will get the XM. It will be useful and I'll love it.
 
My 0566 is hard to flip out , since day one and is still hard to flip.
What can I do to make it easier to flip ?
Is there a way to lighten up the detent ??
Thanks dj

Mine was ridiculously hard to flip out when I first got it also. My fingers were so sore from the flipper. I did absolutely nothing to the knife and it eventually got much easier. It was shortly after that though that the torsion bar broke. So my experience might not be of any help to you. There's a definite break in period with these knives from what I've read. Not sure where I read it but one guy said he noticed a significant difference after he took the torsion bar out, made adjustments to the pivot, played around with it as a manual flipper for a few days, then reinstalled the torsion bar. I have no idea how this would help but he claims it did.
 
Oh I forgot to mention that's it's not the detent causing the stiffness. It's the torsion bar. Because as a manual without the torsion bar, I actually find the detent a little on the weak side. Basically there is a lot of force to overcome before the blade opens enough for the torsion bar to assist the blade out.
 
Just a tip for making it smoother and center it better :thumbup: I saw this video right before I got mine and I did this to mine when I got it and it is soooooo smooth. I also did it to my Skyline and it seemed to help it become smoother as well.

Is yours assisted or did you remove the torsion bar? My 0566 without the torsion bar is also very smooth. My blade was already centred though, and when the torsion bar broke, it was not very smooth. But after removing the bar, I cleaned out all the grease, dust etc and applied some M-Pro7 gun oil to the pivot area an reassembled the knife. I adjusted the pivot screw just to the point where there was no blade play. After this the action was super smooth and was my blade was still centered.

What I think djdawg is trying to figure out, and I would like to know myself actually, is how to smooth out the action and make the blade easier to flip WITH the torsion bar assisting it. When my new torsion bar arrives, I would like try my 0566 assisted again. But there's no way in hell I'm gonna keep the assisted action if it's as stiff as when I first got the knife. It was brutally hard and my fingers were so sore.
Anyone have any ideas?
