Trankada: The joint Locking Techniques & Tapi Tapi of Modern Arnis is the fourth book in the "Modern Arnis encyclopedia" series and is the first book ever to be written solely on the locking and binding techniques of Modern Arnis. In addition to the above, this book does what no other book has done; it details the last major development made by Grand Master Remy Pressas prior to his passing, the Tapi-Tapi. This book covers such topics as: empty hand joint-locking, joint-locking with the cane, joint-locking your opponent with your legs, pinning your opponent, Small Circle Jiu-Jitsu exercises, defenses against striking and grabbing attacks, the template of the Tapi-Tapi techniques and their counters as well.
