Query: Excellent Fencing Book

Aldo Nadi was one of the greatest fencers, and his logic is still the greatest, even today. This is book is about great fencing, not the poke and hack technique (could you even call it that?) that is adopted today. If more people were to read this book, the fencing world as we know it would improve greatly. This book is about what makes the sport great-- Finesse over firepower, courtesy over barbarism, and honor over winning at all costs. Definite recommended reading for those who are already fencing, although non-fencers might find it perplexing. He does outline exactly how to come into the guard postion, how to grip the sword (assuming no pistol grip is implemented), however. Recommended reading for all people who aspire to be truly great at fencing.
