Can't imagine this one being real, with the pink spacers, a strange stamp and the shiny mirror polished blade. I am not an expert but I dear to say this one is fake. I am contacting the seller. Can't imagine anyone buying this knife mistaken it for a real one. Even the shape near the hilt is not straight.
