My experiences with Case factory edge grinds have been varied. Sometimes, they have a pretty rough but sharp grind that just needs deburring. Some have needed a fair bit of work. A few have been pocket-ready right out of the box. One of those, oddly enough, was the lowly $20 black synthetic Sod Buster Jr. Cut like a laser, didn't even need stropping.
I did put in the time and effort to learn how to sharpen properly, so very few factory edges are as sharp as I can achieve. Hence, anything I carry is going to get sharpened anyway. As long as the basic grind is good enough to where I don't have to do any major thinning or reprofiling, I don't mind a coarse grind or a burr.
A couple of Queen D2 knives really taught me to up my sharpening game. Man did those need some work. Also taught me to not be afraid of coarse stones, and to learn to love SiC (i.e. Norton Crystolon) for when you gotta get rid of some metal. Though again, I have another Queen knife that is on par with the best GECs I own, with excellent grinds and a super-sharp factory edge that needed no work.
But yeah, I have had some Rough Rider and even Taylor LLC Old Timers that were usably sharp with good edges right out of the box, better than many (but not all) Case knives.
I don't think I have bought a new Case knife in over 5 years so I don't know what the current crop is like, though.
