I asked essentially this same question from another knife forum about 4 or 5 years ago. The immediate answers I got from them was, "it’s not real Damascus Steel!
I wasn’t asking if modern multi-layered damascus steel knives were made from ancient wootz steel with authentic methods like swords made in 13th century Persia. Simply, if Damascus Steel knives were any better or different then single steel knives, and, if more layered Damascus Knives were better then those made with less layered Damascus Steels?
No one every answered my question. That forum got lost in their cross discussion to educate me what modern damascus steel wasn’t…
I bought that Damascus steel knife I was interested in, back then, and a few more since that time.
Here’s what I can share. The knife’s shape, that is it’s profile and the thinness of the blade overall and of the cutting edge, contributes more to the knife’s cutting and slicing ability, then anything else. The steel hardness contributes to the knife edge’s durability and longevity. Damascus layered knives can add to the longevity and durability, depending on the steels used and the quality of the damascus forging, along with contributing to the aesthetics of the knife.
More layered Damascus steel knives are in my experience, heavier, and stiffer knives and usually thicker profiled then less layered Damascus steel knives. The hardness of the cutting edge, the center sandwiched layer, determines the hardness, durability and longevity characteristics of the knife, as a whole. My favorite damascus layered knives are those made with fewer layers, then with more layers. They can have a nice balance of lightness, edge profile, flexibilty and aesthetics, all in one. I cannot say the damascus layers contributes anything more to the knife then the aesthetics compared to a single steel knife or a clad steel knife.
The damascus layers are very very thin. These thin layers are sharpened along with the single center steel layer as though it’s one piece of solid steel, like any other knife. It’s not like you can tell that your sharpening the middle layer, the harder cutting layer, instead of the softer steel sandwiched outer layers.
