How are there Damascus steel knives if we don’t know how to make it?

[take this post for example](https://www.reddit.com/r/gifs/comments/as9yhf/cutting_with_my_new_razor_sharp_damascus_knife/?st=JSC0ENZO&amp;sh=c3dafea6)
how are they using a brand new Damascus steel knife, I thought we didn’t know how to make it? Or is it not “true” (if that’s the right word) Damascus steel and just an imitation?
Damascus steel is a type of steel that was used in the past, considered to be some kind of "super plastic". [1] Due to a lack of knowledge regarding the chemical makeup of the original ore, true Damascus steel has been lost. [3] However, modern Damascus steel blades are made from a variety of steel types welded together to form billets, which contain strips of iron to provide the necessary firmness on a molecular level. [1][2] These billets are then stretched out and layered according to the needs denoted by the particular application of the blade. [2]
Historic methods of constructing Damascus steel knives with wootz steel are a lost art [1]. However, within the modern day, pattern welding is the most common method utilized to create Damascus steel knives [1]. Therefore, if you have a pattern welded Damascus steel knife with acid etching, it is a legitimate and real Damascus steel knife [1]. Damascus steel was routinely manufactured up until the 18th century when the original source of iron ore in Indian mines was depleted [2]. Due to a lack of knowledge regarding the ore's chemical makeup, true Damascus steel was lost [2]. This metallurgically-magical material is known for its ability to provide a hard, yet flexible, blade that can endure incredible abuse with little damage to, or degradation of, the edge, a rare feat even by today's standards [2].
