my new CQC8 had an off center blade, and i was told to do as follows by a fellow forumite, would give him/her credit, but i dont remember who it was, anyway, thanks again, it does work.
*loosen all the screws (IE pivot, handle screws) but dont remove them. then open and close the knife a few times, and everything in mine seemed to just line up, as if by magic!! ya do have to work it a few times, about a dozen/or so. but it worked on mine. the blade is PERFECTLY centered now, i guess it just had to 'work itself into place'?? after it seems to line up, tighten the screws back, i had to do this twice(loosen/manipulate/tighten)to get it rightfirsttime was almost, but not quite right, second time, bingo!!
there were further steps to take if this doesnt work, but since i didnt need them, i dont remember, am sure someone will chime in w/them, though. try this first.
good luck
