Which screw to adjust?

    I just sent one of my ZT560 back for warranty and I pulled out the other one that I just got back from them. They fixed all the issues. I do like it except I think I need to adjust something.

    It flips open nicely with the flipper but I can't use my thumb to open the knife. It takes a lot of force. The other 560, I could use the thumb stud easily. Actually, before I sent it back, I could just hold the handle with my arm hanging down by my side, snap my wrist, and the blade would deploy. I don't want to go about this blindly so I am asking. Can I loosen either the lock bar stabilizer screw or the pivot to require less force to open the knife using the thumb stud? Which one? And it's odd to me to think I can adjust with a screw as I think, conceptually, one is just suppose to screw down screws to a certain torque.

    There is no screw to change this, except the pivot if it is too tight.

    They are also technically not designed as thumbstuds but as stop-pins which can be used as a secondy method of opening.

    On your old knife the detend might have been a little softer which allowed for easier opening.

    I would not suggest trying to manipulate the lock or pivot in any way.
