Not sure where I should have posted this. I bought a zt 0561 from a dealer. When I was there it was not flipping, got it anyways thinking it just needed to break in. Well it's been about 2 months and still only deploys about halfway when using the flipper. Tried researching the issue but didn't see much on the zt being faulty. Just took it apart but everything seems fine. Thumb studs deploy the knife fast. Thoughts or ideas appreciated
