Just got mine. Massive blade play side to side. I noticed it immediately when I opened it up and did the compression lock flick (press compression lock, flick knife open and release to lock). The blade immediately hit the blade stop and made a short ringing/rattling sound like the washers or blade were vibrating. Checked from blade play and there's considerable. If you hold the blade open and shake the knife you can feel the rattling of the blade, and sometimes hear it although it's hasn't done it the last few times. Going to need to get this resolved if most times I open the knife I am going to keep this rattling/ringing noise.
All screws are tight, including pivot. Pivot screws are loctited shut, rather not risk destroying them.
