I purchased two Manix 2 black blade (C101GPBBK2) knives...one each from two different sellers. The most striking difference is the amount of light reflected by the blade:
The one on the top IS a black blade but reflects so much more light than the one on the bottom.
Then the pocket clips are at different angles:
Finally, the letters on the front of the blade appear to be the same font but are just slightly thicker on one of them (and again, notice the greater reflection from the one on the right):
Any thoughts on whether one of these is fake? Is this natural variation? Is one from an older batch and the other from a newer batch? I can tell you which knife came from which seller, but I want to withhold that information so as not to influence the responses.
