Well did some trading to get this one from SC-Rebel(Ron). Great person to deal with by the way. Now for this CQC7. It isn't an A model or a B model just says CQC7 on it. It is a CE blade and if I am not mistaken it is about .5" longer than the last CQC7A I owned. This has green scales with what I would consider nicely polished liners, which all my other EKI's didn't have. Except for maybe a Comm. This has a far better edge on it than any previous ones I have owned. Also an extremely good point to it. Again good enough to stick easily into my cutting board. The edge is good enough to easily shave hair and slice paper with 0 drag on it. The serrations are on the smallish side but like the plain edge they are rippers. Very sharp indeed. Lock up is just a bit past mid point on the choil and is rock solid. Took it all apart and cleaned it and then teflon taped everything down after a bit of lube in the right places and voila a new EKI fan is born. They should all be this good! Keep'em sharp
