Book excerpt: In the study of unconventional warfare, few names carry as much weight as Michael D. Echanis. The shadowy hand-to-hand combat pioneer died under mysterious circumstances, but before meeting a violent, fiery death in an unexplained plane crash in Nicaragua, he penned Knife Self-Defence for Combat, the definitive guide to controlling and disarming a knife attacker and a must-have for any paramilitary operative. Previously unavailable to the general public on the open market, this modern mercenary's favorite contains more than 30 fully illustrated techniques.
