Folded steel
Just what does it mean? I've read a lot on several sites that the sword is made of hand tempered folded steel, but just what does folded steel mean? (And if you're wondering what a 17 year old is doing here I so happen to be interested in swords and will probably start with either kendo or hapkido sometime soon) |

The process of folding steel for a sword blade is to me quite self explanitory. First you have a billet(brick) of mild(low carbon content) steel and a billet of high carbon content steel. They are heated at the same time in the forge and when they reach the proper temperature they are beaten together until they form a single billet. then you would flatten the billet out enough as to alow you fold it in half and beat it together again. this process of folding the steel over and over again is what they mean by "folded steel" you may also have heard it called "pattern welded steel" or "damascus"(not "damascus etched" mind you.) |

The man above gave a good explaination of what it is, but failed to tell you why they fold it. The reason is because steel used to be hard to make. The best steel that could be made was called "blister steel". This is a block of iron with very high carbon content in some spots and nearly none in other places, thus forming "blisters" of high carbont steel. In Europe to overcome this they would twist and weld the blade bar into itself producing a strange wavy pattern. It was still uneven, but the distribution was slightly better. This is what is called damascus steel. (Cool side note-Some parts of the edge would wear out faster than others, resulting in a blade with a micro-serated edge) Anyway, to the cool part. In Japan they found a different solution. By folding a bar of blister steel and regular iron into each other a few times (just 7 would produce over 250 layers) they had a sword which was, in effect, an steel sword all they way through. I hope I was of help |
