Disassembly wasn't needed to smooth out. He disassembled to remove some of the lube. I spoke with author of the video and the blade play was due to the lack of Loctite used as the pivot was backing out. Upon adding Loctite and tightening the pivot down blade play was gone. The smoothing out issue is common with most any knife in my experience. The pocket clip should be easy enough to remove and bend to the desired tension. While it really shouldn't have any of these issues on a $400 plus knife they are fairly simple to correct but the disassembly was not necessary to correct any of them.
