I don't think it was damascus.
it was actual bronze age sword.
I saw it in a histroy book when I was in the 6th or 7th grade.
Too bad I don't have the picture now, it was a beautiful sword.
It also shown two or more rods of soft iron.
I think a metal, maybe iron, with a certain sulfure content was used for the picture and each rod were about an eighth to a quarter inch thick.
It also shown the metal being twisted, turned and pulled into certain patterns, like a rope.
After the rods were twisted into pattens, they were then hammered flat, then forged, making snake like grooves into the blade, making it also very strong.
The handle was made this way also, but it seem like it was done last, and wasn't as detailed.
Whoever made it though had to be very strong and skilled blacksmith.
I'll look more into this for a picture.
Until then, you could experment with some scrap iron to see if it works.
