I got an 882 in trade, and overall I'm impressed. No it isn't an 880/881, but you can actually carry this in a pocket, unlike the 880 I had.
Lockup is solid, no blade play, and the liner lock cannot be dis-engaged in any grip (unlike some other knives I've had). I do not pry with any folder, nor will I whack the spine to see if I can cause failure. Personally, I don't see a need for a thicker liner lock, but if Buck does it, then it only makes the knife tougher.
The grip and choil allow you to choke up on the knife, and the rough finish on the blade allows you to hold it by the blade for fine work.
Serrations. I'm not a fan of them on any blade, and I can't see the utility of 1" of them on any edge. Not a rip on this knife, just serrations in general.
It is also much more comfortable to use than the blocky 880.
I don't see it as a replacement for the 880, you want one or the other, or both but for different jobs.
