I'm carrying a Case medium stockman today. 6318 Pocket Worn Old Red Bone in SS. To me, there is nothing wrong with it (well, one thing, but I'll get to that). Slim serpentine shape with rounded bolsters carries easily.
I have all three blades razor sharp after spending a little time on some Arkansas stones and a strop. The factory edge was sharp but with the typical burr that needed stropping off, but a little more toothy than I generally like. It was certainly ready to use once the burr was removed, but I prefer a bit more refined edge. The 420HC steel seems to like Arkansas stones.
Good looking and good feeling knife with a consistent dark red dye on the bone. They usually do a good dye job on the Pocket Worn Old Red from my experience with them.
Good walk and talk and nice snap on all three blades. Smooth, non-gritty consistent pulls. In general, just a fine pocket knife. I don't recall what I paid for it but it would have been less than $40 at the time, bought unseen over the Internet from an auction site seller that I'd done business with in the past. Factory new, never opened or unwrapped.
Now like I said, there's nothing at all wrong with it. It has blade rub. All crinked-blade knives I own have blade rub, no matter who made them. So to me, that is not an issue. It's just how they are made. There is a little bit of a gap, visible if you look for it but not big enough to get a piece of paper in, between one of the backsprings and a liner. When the main clip blade is fully open, the backspring is just a tiny bit proud. Not something I'd normally notice without looking at it up close. I've got more expensive knives from other companies that are much worse in that regard.
Now - the one thing I mentioned before - the sheepsfoot blade sits a little higher than I like when closed. It is normal for the 6318, but I find I like to file the kick down a little to lower it some. Just personal preference and something I have done on a few other stockman patterns for the same reason.
So - some people may approach it as "coarse blade grinds with a burr, backspring gap, proud sheepsfoot when closed, and blade rub, what a piece of junk." I approach it as "what a great looking and great cutting knife. Needs a couple of minor tweaks and ready to go."
So it's all about your expectations and what makes you happy. If you get out a magnifying glass and inspect your pocket knives looking for flaws, you'll find them. I'd rather be a little less observant and happier with my knives. As long as they work well, feel good in my hand, and look pretty to the naked eye, I'm willing to overlook little issues that I would never have noticed if I hadn't gone looking for them in the first place.
I've got a few Case knives that I'm not overjoyed with, but in general they're good enough for me.
