Shuto Gedan Barai is a fundamental technique in Shotokan Karate, characterized by a downward sweeping motion using the knife-hand (shuto). From a ready stance, the practitioner raises their arm to shoulder level, elbow slightly bent, and executes a swift downward sweep to block low-level strikes aimed at the lower body. This technique is crucial for defense against kicks and sweeps, emphasizing precise timing and control of movement.
