Konnichi wa, I had checked out this book on "Secrets of the Samurai" and found a lot of good information on almost every Samurai in Japanese history. I also found a small stroy about the blacksmiths Muramasa and Masamune. they were blacksmiths who created the toughest and sharpest steel. But one of them was considered evil along with his sword. How true is this story?:bow: does anybody know or heard of Masamune and Muramasa?
