Iv seen a few fakes here in Taiwan and if you are familiour with the real thing I doubt you would be fooled by one.
The things to look at are the screws and placing of screws being off,
the blade finish and grind are usually sub par at best,
the logo while able to be coppied fairly well is usually placed badly and just dosnt look right (its not been laser etched on the ones iv seen).
The g-10 texture is not the same and the finish and always looks wrong.
The spacer is never the same material EKI use and the thumb discs are odd looking too.
The price is usually a bit of a give away as well
