I have an idea for a new thread...

[gummibear]

Please tell us more. Is that the same as Damascus steel? Is that effect achieved by folding and beating? Who made it?

 

Yes it is Damascus steel and made in Germany by a blacksmith.His son makes the knives.I bought this one at a medieval fair here in Lux but I also ordered a few off ebay but can't get them delivered here,so i will collect them when i am in SA.

400 layers? Just out of curiosity, how does that work? You take a sheet and hammer it flat, fold it, hammer it, fold it, hammer it, and so on right (heating it in between ofcourse). So if you start with the first sheet(1'layer") and keep folding it, the layers add up like this: 1:2:4:8:16:32:64:128:256:512 isn't that right?

 

EDIT: ooh and "howmuch" do they cost? :-)

This reminds me of an old maths teaser: if you could fold a sheet of paper an infinite number of times, how many folds would it take before the pile of paper would be high enough to reach the moon? I don't remember the exact answer, but it's a lot less than one thinks and, of course, the last fold takes you halfway there.

Originally Damascus steel was made up of remelted steel, often of different grades, which caused the mottled look....or so I was told by a knife maker.

This one i bought on a ebay auction for $40.

I am sure that this steel is pushed out by big companies using hydrolic presses and not a guy hitting it silly.AFAIK they start by welding different grades of steel together and then heating it and hitting it and they do that over and over.

Look closely and you’ll see two moving objects in this. The most obvious one is a meteor however, more subtly in the middle towards the top right, there’s a small object moving slowly up and that is a fuselage of a Russian rocket breaking up in the upper atmosphere.

I thought you could only fold a piece of paper 7 times...
