With a good enough fake, you can fool anyone. They tend to be too large, which is obviously hard to tell in a picture, and some of them have silver screws, which is a dead giveaway. The best thing I can say at this point is that if you can't be confident due to the source of the knife which is a fake and which is real, shop elsewhere. I really wish that wasn't the case, and believe me, the counterfeiters upset me to know end.
