And wavy pattern on sword surface is made not only by forging but also by quenching. And also beautful wave pattern is controlled by raw material"Tamahagane".So tamahagane is made by ancient steel making “tatara” which high-tech steel maker Hitachi Metals deal with.

In the oldest japanese myth litarure "Kojiki",it was written as a imperial treasure sword that was gotten by the god Susanoo.It is thought that japanese myth is still alive with the last emperor "Tenno" in the world.

Today we "manufacture" Damascus by using two or more very pure types of steel. We use a precisely temperature controlled forge, we understand the atomic structure and metallurgy of the materials, and everything is controlled for. In the past, those guys were digging raw materials out of the ground and learning from trial and error. They probably didn't even think much about the appearance of the steel. In fact, they would have been more impressed by our extremely clean looking steel which has no impurities in it. John That is true. This is a very good point.

Many older blacksmiths found that Damascus steels had markings like they were pattern-welded, and so called their pattern-welded steels Damascus steel. However, true Damascus steel was not formed via pattern welding but by crystal propagation of iron carbides within the metals caused by very specific impurities.

I've seen them use a type on which you grind material off on a running band of sand paper, but the difference i suppose is that you are holding the knife and not the tool... aequitas hey,
