Book excerpt: The jo appears to be the lowliest of all tools--an ordinary length of wood--yet it’s an exceptional weapon. While no one speaks of famous jo makers the way they do of sword smiths, the jo is capable of snapping the best swords ever forged. Packed with information on correct grips, stances, postures and etiquette, the book also outlines striking methods, combination techniques, and a 31-count formal solo exercise called tandoku renshu, making it the ultimate resource for those who appreciate Japan’s most subtle weapon.
