Miyamoto Musashi is considered one of the greatest swordsmen who ever lived winning 61 duels. He was known for his unique "dual wielding" style when at the time everyone else was using only one katana. He was so good that in some occasions he would humiliate his opponents by using wooden swords instead of real swords. Musashi also wrote a book called "The Book of Five Rings". In this book, he explains his view on tactics, strategy and techniques related to swordsmanship. It's an amazing book. Al
