My $25 Kershaw Blitz locks up real tight, is centered, stays put when I run, has opened up boxes and cut wire without chipping, and no screws or parts have flown anywhere.
I don't think the OP is wrong to expect at least the same from a $200 give or take knife.
I've got several Kershaw knives that are dandy daily use, light-duty knives, and you're absolutely right. They work great for cutting open a box. I even have one for which I paid triple, as it had the Snap-On name, and I got it off the truck. Very handy.
I'm guessing you've never actually needed to defend your life with your pocket knife, or that you've never been put in the position where it's a distinct possibility...and where reliance on your knife is a little more than merely concerning yourself with cutting open a cardboard box.
I've no illusions that my Kershaw cutters will stay in my hand when it's slick with blood. They won't. I've no illusions about the fine motor skills needed to snick off the little plastic safety before flicking open the knife. Fine for cutting boxes, not fine for use understress and theat of one's life.
My emersons are knives that I do depend on, and which I have depended on in some rather unsavory places (the kind of places where there is no question of the nature of the threat). I took my Kershaw knives, or at least one of them, as well...and it made a handy box cutter.
My knives aren't pretty, and aren't collector items. They're called hard-use,and they get used hard. I've had no items fall off, no screws fail, nothing of the kind, in any way, shape, or form. The only failures of any kind, if they can be called that, were a couple of pocket clips which caught on an object and got bent, when I pulled away. I still have the knives. My knives have been in and out of combat zones, bad neighborhoods, and have seen service in shops, on the street, in the woods, in the rainforest, in the desert, and even in freezing arctic places. I've cut into wood, rope, metal, and flesh. Even cardboard here and there. My knives have been sharpened, oiled, bled-on, and used. Some are worn, some are pristine-new and waiting to be worn. And they will be.
I'm far more interested in a knife that will take me where I need to go and return with me, than whether the knife is pretty. It's a tool. I use it accordingly.
I'd rather see a nice fit and finish, and I'm quite sure this is possible. It is, however, a production knife, and it's one made in the US, and it's one with a respectable reputation that I proved for myself. I'm not concerned about "cool aid drinking." I made the knives prove themselves for me, and they have, such that I have no doubts or concerns when I carry them. When I put an Emerson knife in my pocket or sleeve or belt, it's not there for the name, or the looks, or for the reputation. It's there because it earned the right to be there, and because I trust it.
You have experience with your Emerson knives that says differently?
If so, then go with that experience. If not, gain some experience, then report back.
