I've read this book more times than I can remember. It's very smart. The "way of strategy" does not seem to have changed much in the last 500 or so years and Musashi's ideas are still applicable today to zero-sum games.
He was known for wielding 2 long swords, but IMHO, directly relating the techniques he describes to double stick, or whatever, would be vastly underestimating the concepts that make up most of the book. As he says, if you "know the ways of men", the weapons become secondary.
I bet Musashi could do more damage with a plastic spoon than most people wielding a stick ... if plastic spoons had been invented in the 16th century..
