Does flipping open a folder shorten the life of the lock?

Pretty new to folders and I will be up front and honest to knowing jack about terms like detent and lock rock, but recently I found a folder I actually like an want to keep, a ZT 0550. Since owning it I noticed the framelock (I think) has been locking deeper on the bottom of the blade. Nothing drastic just like it started at about 10% of the blade and now is at about 25. Is this normal? Should I not flick it open? Does flicking it open damage the lock over time? Will the lock ever get to a point where its completely on the opposite side? Thanks for the help.
 
Locks wear, I'm sure that KAI/Kershaw/ZT will have no problems fixing when the time comes.
 
Its simple wear and tear. Even with my Umnumzaan, if I rapidly open and deploy the blade, I notice the lockup is deeper, from a standard opening lockup of about 30%-45%, to 65%-70%. You can trust with a ZT that you've got good, hard blade material. And the framelock bar should holdup too. Personally I don't prefer flicking the knife open. Your hands should be able to do it in a nice smooth, repetitive fashion, but whatever. I'm sure your knife will be fine and if anything goes downhill, I'm sure ZT/Kershaw will remedy it. They appear to have an excellent Customer Service warranty according to others on this forum.
 
When one piece of metal rubs against another, in time, one or the other will get smaller. There seems to be a short break in period with folders. I found that the harder that you flip a blade the deeper the liner or frame lock will go. Some makers have a replacement tip for the liner lock. With normal use yours should last quite a long time. Zero Tolerance makes a quality knife.
 
Not sure of your age but I would ventue to say that your thumb joint will wear out before your lock bar / blade tang does.
