ZT 0550 grind issues?

I agree the para 2 is an awesome knife, and I still carry it all the time but it is also a finicky knife...I always have to adjust it though, the pivot can become tempramental if the knife is jarred or dropped...takes a bit of time with some loctite and a torx to get it right again.

You seem to have a lot of trouble with knives...
 
I am still curious if anyone has noticed the issue with the detent ball I have with my knife...? Open it slowly and you will probably notice that the ball hangs up in two places very close together just before the lock engages. I'm fairly sure it has to do with some sort of manufacturing process and at this point my curiousity has got the better of me and I want to know why? Lol!
 
The grind on mine was also not very good. Not too much of a problem since it needed a reprofile on my Edge Pro given that it was >25 degrees per side. The only issue I still have with the knife is the detent is weak. Just a slight shake will have the blade dropping open.

Here is a pretty bad picture. Still need to take one of the new edge profile.

Figured this was going to come... I am a bit picky, most of my knives (spyderco and BM mostly) are pretty close to perfect, like the para 2 is. But, I found that if you do use it hard or drop it the wrong way
the pivot can break loose or the liners can become mis-aligned. But I have never owned a ZT or a framelock for that matter and the things I have noticed so far bug me a bit.
The issues with the para 2 I have noticed do not though, because those issues are due to the design of the knife itself.

What are you doing with your knives if you pivot breaks loose often? Also do you drop you knives often? How high do you drop them from?

I have dropped my share of knives and if they're closed, the tend to open a bit or all the way. Unless they fall on their tips or their edges, I tend not to get ANY damage or misalignment. Well, sometimes the scales get dinged.

The grind on mine is just like yours on one side and a fair bit higher on the other. All of the blades I looked at were the same way, with close serial numbers. I would have to bring the edge a fair bit higher to match them.

I am an electrician and I use my knives at work, for work. So they do get dropped from time to time. I have ONLY had this problem with the Para 2. But it did not come like that new, and is easily fixed if it does happen. So that is why I mentioned it was finicky.

I have to respectably disagree. I have heard enough excuses just like that when I started a thread at Spyderco's forum recently raising a similar issue. At the end of the day, it all about quality control and the attitude towards the end users. $200 for a knife is NOT a small number, The minimum wage is $7.25 per hour in this country, so a fair amount of attention should be paid to reflect the price premium. I would not be surprised that the knife in question was made in USA. The only Spydercos that I had problems with are mostly American made, their Taichung production lines are excellent.

If I was not mistaken, all ZT’s are made in USA, their Shun Japanese division builds excellent products. I own many Shun’s, never had single problem, great grind jobs on every piece, and most of them are under $200, so go figure.

You may now feel the urge of accusing me of being against American made products. Not at all! But comments like this are about the most unpatriotic thing that anyone could have done. Why? Because you are not doing American makers any good by sending message that what they are building is just fine. Comments like this have been sending that message for a long time and the makers are reading it loud and clear. Is it a time for a change? You bet!

So I guess I'm figuring you feel American knife manufacturing is in the toilet, but everywhere else is perfect? Time for a change...?

Please pardon me if I misrepresented your thoughts.
 
I own over 20 different Para knives and none of them have a loose pivot,at all. Especially the Para2. The pivot bolts are tightened down all the way and they don't move at all.

I have an 0561 and the grind is perfect. In fact, it came with the best factory edge/grinds I have ever received on a production knife. A tiny bit of stropping and it whittled hair. My latest Delica (ZDP) did come with with a perfect edge. It has a bit too much ground off, and near the ricasso ended up being quite a bit lower than the edge. But, it is what it is. I have never seen a primary or secondary grind that cant be fixed with a bit of elbow grease. Some people don't like to put in the work and that's fine. Myself, I don't see why I would miss out on a great knife even if the factory grinds aren't up to par. YMMV

Yes, I have to respectably point it out since you asked, you did misrepresented it.

I gave a couple examples as Excellent executions. But "excellent" does NOT equal to "perfect/flawless", it is way more than acceptable at their respective price points comparing to their American made counterparts. What I've mentioned was from personal experiences, YMMV. But the comments I was replying to sending a wrong message which does the makers no good.

Yeh, I have about 5 paras and another coming and I have the same experience as Rev and Bernard.

I guess our experience trumps your opinion. :p

Well, in my opinion, it is :)

I guess I got a bad one, I cannot tighten the pivot down all the way or it wont open, and when I get it loose enough to open smoothly it has play in it. Do some reading on the net, there are people with similar issues.

Like I tell people with their car. "If you have this many issues with your car (knife), than It probably isn't for you. I would suggest you look for something else". We have a customer that GM has given her 4 brand new cars and she is in nit-picking every week about something else.
 
Like I said, still use the knife...those issues dont bug me that much. If it did it would be in the mail to Spyderco already.
