There are a few things you can look for to determine if a Damascus knife is fake, these are:
How it looks
The most obvious sign that a knife is fake is the lack of a wavy pattern on the blade. If the blade or knife looks completely smooth without the intricate design, it’s likely not made from Damascus steel.
Quality of Metal
The quality of the materials used in the knife can also signify that it’s fake. Damascus knives are made with high-quality materials, so if the blade seems to be made from cheap materials, then it’s likely not authentic.
Price
The knife’s price can also be a sign that it’s fake. A Damascus knife is typically more expensive than other knives, so if the blade is being sold for a lower price, it’s likely not authentic.
