I've had my Backpocket for a couple days now. I wanted to carry and use it a little bit before I commented. It is a very cool knife. The fit and finish on mine is superb. Out of box sharpness was good. The grinds are even, the swedge is symmetrical and crisp. The backspring is flush in all three positions. The blade is perfectly centered. The pins are perfectly round, flat and flush. The shield is perfectly fitted. The ebony is dark, even and rich, the lanyard tube is very nicely executed. There are no gaps anywhere. The only, tiny issue with this knife was that there was a little bit of polishing compound in the pivot, so the action was gritty at first. After being cleaned out, it is nice and smooth. Pull is about a 5 or a 6, right where I like it.
As I promised above, here is a side-by-side image with a GEC #23- albeit a terrible one. The bolsters on the Case are fine, what you see in the image above is just a fingerprint.

The knives are fairly similar, both being single-bladed, Remington-style, 4 5/8" trappers. But they vary significantly in the details. The Case is thinner and lighter. The GEC has a flat-ended joint, while the Case does not. The swedge on the GEC is ground to a harsh point which can catch on your hand when the knife is closed, the swedge on the Case transitions smoothly. The nail nick on the GEC is positioned directly above the finger swell in the handle, so that it is hard to get to. The nail nick on the Case is positioned properly, so that it is easy to use. The Case has a lanyard tube, the GEC does not. The GEC has domed pins, the Case has flush pins. The blade profiles are different- with the GEC having a sodbuster flavor, the Case has a pronounced clip. The GEC has more belly, the Case is more sexy.
I like both knives. The Case is certainly a worthy pattern. I don't understand why it isn't being better received. My one concern with the pattern is that the scales seem a bit thin. I would personally like to see them a bit beefier, but the knife overall seems plenty stout. Blade and liner thickness is identical to the GEC #23, which is considered a super heavy-duty knife. The Case is certainly easier to use than the GEC, as it is much, much more comfortable to get open.
As for Case's quality "deteriorating", I do not believe that to be the case (no pun intended) AT ALL. My backpocket is made to the same level of fit & finish as my Swayback Jack, which has the reputation of being a superbly finished knife. I find current production Cases to be favorably comparable to any other current production knives on the market, period. This includes GEC, which I like, collect, and own many of.
