Although there are some great products coming from overseas (even some great companies making pretty good knives in... China... although they are licensed products of these companies and not clones) clones are a whole different animal, it seems. And it isn't just with knives.
Recently my younger brother brought a hard drive to me, for his gaming system, as he was having trouble playing some games on it. I did some tinkering and through some sleuthing and some testing managed to figure out it was a very, very convincing clone of the actual hard drive he needed for his product. The difference being the clones CAN do most everything the real thing can, and look good doing it, with the exception of playing some of the games he was trying to play... that part they can't crack yet. In fact in this industry, hard drives like this aren't even sold as clones, but AS the real thing, WITH very convincing packaging and markings to boot. That's how they managed to fool him into buying it (and likely fooled the dealer into buying them as well).
I guess I use that example just to say, while I think there are a lot of great products coming from overseas in general, I think clones in any market, especially if they are intentionally trying to say they are [insert knife brand here] is a terrible practice. I'm not saying that's what was being done with the knives you picked up, (though that may be) but clones tend to leave a bad taste in my mouth, I'm afraid.
I can't fault you for finding the edge, cutting, fit and finish or whatever good, if it's good it's good, but I still think it is somewhat questionable. Through life experience I've also recently learned of a trend in business known as "dumping."
I'm going off on a tangent here but I guess my point is, there are certain rules, and it becomes distasteful when they aren't followed. Not trying to jump on a soapbox here in any way though.
