When I first got this knife there was silicone oozing out of the scales, gritty button, and slight play. I took the knife apart, thoroughly cleaned and lubricated it, and now it is about as good as it gets. No play whatsoever, no more silicone crap, and it even snaps out faster. The pivot has a T10 and the body screws are T7 size screws. Here is a video of the process of dissasembly and reassembly:
