I'm one who really likes the new pivot bushing system. I love the way it allows the blade to fall so freely it can literally almost "drop" open itself once the blade is pushed past the detent that holds it closed. I sort of "pinch" the blade against the handle to get it past the detent and then it just effortlessly and gently drops open with just gravity and the weight of the handle, in a way that doesn't put undue stress on the lock mechanism, stop pin, etc.
And it likewise closes very effortlessly with one hand as well.
Everyone's entitled to their opinion of course but personally I'll gladly take the very slight lateral or horizontal blade play that isn't noticeable to me at all when actually cutting anything in exchange for these highly enjoyable features or benefits provided by the P2's new bushing system (assuming it's properly adjusted of course).
