Mark Kline is a professional martial artist specializing in the study of Kyusho Jitsu (Pressure Point Fighting) as related to martial arts, not for health, but for real life protection. Dr. G. Kikuta originally wrote this book, 25 Lessons in Official Jujitsu, in 1905. Mark Kline has used his expertise as a pressure point specialist to add to this historic manuscript. Each lesson is presented exactly as it was originally published 105 years ago. Mark Kline has added to the manuscript by going into more detail with the weak areas (Kyusho) of the body presented by the original author. This work was too important to let it sit on a shelf collecting dust. So take a journey back in time and get a glimpse of how martial arts was practiced at the turn of the last century.
