I just received mine so I did the preliminary comparison to compare to my older and non-CQI Spydiechef:
The lock up seems to be even later than the first Gen 'chef which I used to own! Just by eyeballing it, looks like 75% lock up; I don't have my older one anymore, but just going by my fuzzy memory, it wasn't as late as this newer version.
The dreaded lock-stick is again present, just like the older one had it which I eventually had eradicated by using the Sharpie trick and copious amount of opening and closing, repeat x 100s! I have gone ahead and applied Sharpie to this one's tang too and will repeat the previous routine!
That annoying lanyard hole barrel rattle is there too, FWIW.
