Jeet Kune Do (Way of the Empty Fist) or Jun Fan Gung-fu (Bruce Lee's Kung-fu) is the modern martial arts system and philosophy created by Bruce Lee and further developed by Guru Dan Inosanto amongst others. The "style of no style" is known for its mixing of techniques from various systems and its refusal to be enclosed into one traditional style. Empty hand-to-hand combat in regards to hand based techniques in Jeet Kune Do are generally made up of, but not limited to, Wing Chun, Western Boxing, and Kali. Lower body techniques are by and large Muay Thai, Savate, and Kickboxing based. However, Silat leg trapping techniques are also utilized. Grappling methods are generally from the Filipino martial arts, techniques called Dumogs, while other locks closely resemble Japanese Jujutsu. Weapon based combat is a combination of the Filipino arts Kali/Eskrima/Arnis and Fencing. While some schools and instructors will also emphasize the staff, nunchuka, etc., the main weapons used in Jeet Kune Do are the stick and the knife; Fencing is used for its footwork and deceptive lunging and bating techniques.
