How can you tell fake damascus steel from real damascus steel? I just bought some knives that were etched pretty deeply to show off their layers. Some of my friends added their 2 cents in and suggested that it may be fake. Now I am wondering. Along the edge grind, I can see minute spots of rust here and there. I thought it was from the one type of metal rusting and the other type not. Is this a way to tell? The pattern is pretty deep, or the acid etch is pretty deep. You can feel the uneven surface when you run your finger across it.
