Imgur-user feadpool shared this fascinating look at sword history, starting with the mythical swords of samurais and Vikings and proceeding into a more, depthful look at medieval metallurgy. Game of Thrones should find this all very interesting!

"Samurai swords were way better than anything made in Europe!"
Not true at all, the reason Japanese swords are so mythologised is because Japan has very poor quality iron, it takes a great deal of skill to turn it into sword-quality steel, folding it to mix out impurities and strengthen the material.
The same general principles were used in Viking era swords resulting in beautiful pattern welded swords. They mixed different types of iron and steel, some very hard, some more springy, then folded and twisted them together to mix the properties and create beautiful patterns on the steel.
These swords were considered just as magical as Japanese ones, they were named & honoured, passed down generation to generation & considered to be nearly alive.
