    I want to say from the get-go, that I really like this knife. My problem is that despite tightening the pivot screw, I am still able to open the knife with just a flick of my wrist, no usage of either the flipper or thumb studs. By definition it is now a "gravity knife", which is not legal here or in many other places. Any ideas/help would be appreciated!

    Is this a joke?

    One guy was just complaining about it not opening up easy enough?

    It has the detent, to keep it closed, it should be visible.

    I think since you have to flip your wrist it is not just gravity its centrifugal force as well. I think gravity knife is more aimed at balisong's/butterfly knives where you can drop it and turn and it will open without the hard wrist flip.

    My Groove opens like this and I love it!, I can flip it, wrist flick it or pull it out and push it around with my thumb.

    Not a joke on my part, definitely a concern.

    Post a vid of your issue. It seems contrary to issues others are having.

    Are you just saying that the detent is weak?

    I can't post a video, have to be up at 0400. I can hold the knife on it's side and without touching the thumb studs or flipper, I can have the blade deployed and locked in place.

    Tried again to tighten down the pivot screw, broke two torx bits. Pivot screw is as tight as possible, and I can still open the knife with a flick of the wrist, without using the flipper or thumb studs. Unless Thomas or someone else has the answer it will be going back...I REALLY like this knife, but a "gravity blade" is a definite no go both here in NJ, and in WV where we have our vacation place.

    I would give the lockbar a slight bend - it will help slow the speed of deployment and get that detent back where it's supposed to be.

    So, I would have to disassemble the knife to give the lockbar a slight bend right? Will my bending the lockbar void the warranty? I really want to keep this knife, but I really want to maintain it's warranty and value also...

    I have now destroyed 3 torx #8 bits trying to loosen the pivot screw in order to disassemble the knife, and can not loosen the pivot screw. So, does this go back to ZT or the dealer to fix?

    Try calling the dealer and hear what he has to say. If you've got a customerservice-oriented dealer that would be willing to swap your 560 for another one, then let the dealer have it. If you have to wait for the dealer to send it in to ZT, then you might as well do it yourself and save yourself some time.

    Deal with Kershaws directly. Send it back, sounds like a defect.

    Kershaw/ZT will fix it. Just contact them. I have found they communicate with you very well through email. They will fix it for you no problem.

    I had to use a lighter on my 0551 to get the pivot screw loose. My small soldering iron didn't work. I heated up the pivot on the Ti side until I was able to turn the pivot screw. They use mucho loctite when assembling their knives.

    Is your problem that there is NO DETENT? Or is the detent just weak?

    Yeah, sounds like it's just missing the detent ball. Either way sending it in would be the best bet.

    If you can flick it open by wrist action only, it's still considered illegal, at least in Canada, California and a bunch of other places.

    Hopefully this is just a one-off problem, and not in a bunch of 560/561s!
