George Kirby spent his life studying Jujitsu and produced this excellent, insightful, learning resource on Jujitsu as a result of that dedication. Kirby formed the American Jujitsu Association and also involved himself in law enforcement. With Jujitsu, Kirby has written a book that would shape America’s understanding of the style for decades to come, which has always been his goal, to help martial artists develop a better working understanding of Jujitsu. This book will help advanced practitioners and new grapplers quickly put basic Jujitsu techniques into motion.
