There was a very interesting program on Nat Geo recently called' The Samurai Sword.' It highlighted only on the making of the Katana in the true old way, right from the Casting the steel in the foundry, the forging process at the forgemaster and finally the sharpening of the sword by an expert. It also briefly explained the way Samurai used them. A few Kenjutsu masters too came on the program.
