I find partial serrations annoying. The serrated part is often too small to be of much use and the lack of continuity messes with usage. Serrations are handy for cutting line, but full with maybe a small section non serrated at the end for fine work seems a better design. If you keep it sharp and aren't regularly cutting mooring lines the lack of serrations probably won't be a factor for you.
If you get that knife I would remove the screws and apply threadlocker and reinstall, as cheap knives will have cheap fasteners that back out, get loose, and damage the threads doing so.
The blade steel is 8Cr13MoV. That's fine if the manufacturing process went well. If it didn't it's not, but that's the way it is with a lot of things nowadays, including expensive products.
Do small serrated portions help considerably with belt cuts? I've practiced cutting a couple belts with a CP after shooting up junkers but it's not something I've practiced with a person in the vehicle. I have belt cutters in my vehicles. Anything you've learned in actual practice that would be handy to know?
If you like Kershaw's stuff, prefer US production, and want to save a few bucks, you might want to check out Kershawguy's seconds page. My Leek is from that site and I can't find why it's a second. It's the nicest folder I've had.

Perhaps get both Kershaw knives and carry the less expensive one the next time you pour cement or do something else which risks loss of the knife.

I can't say with any certainty, but I think they do. Understand my sample size is so small that I wouldn't take my word as gospel by any means. I did use that knife to cut an uncooperative person free of his seat belt. He wasn't combative, he was high on wet and t-rexing so his arms were flailing near his chest and I wasn't reaching across him to undo his belt. It went very quickly, but I can't say that one of the zipper cutter things wouldn't have worked as well. There may be some difference in angle and strength to cutting someone else out vs cutting yourself out as well.
I *can* say the window punch works a treat and requires much less force then you'd expect it to. The first time I used it I put my entire hand through the window first blow. After that I learned to tappy-tap and not hulk smash.
