LED Sabres
Paul Silk is an instructor of the The Silver Sabres Combat Academy (SCCA), a LED Sabre school, teaching traditional sword arts for the purpose of Competitive, Dramatic, Live Combat! The amazing LED sabre is beautiful to watch in motion, safe to use for contact work, and balanced perfectly to allow the study of genuine sword arts. The SSCA core discipline is centred around longsword techniques, with other disciplines becoming available as students complete their basic training.
The internal syllabus is taken directly from traditional Wu Shi Taiji Quan, and the external syllabus is a pure geometrical system based on human anatomy, known as the Eight Spheres Geometry of Combat.
