The late Grandmaster Wong Shun Leung gave a pair of Butterfly Knives to Tommy Y.K. Yuen. At that time the only BJD suitable for actual use in combat were full custom knives unaffordable by most martial arts practitioners. Most practitioners were forced to train with poorly designed low-quality swords (made by manufacturers with no understanding or love for the art) that were incapable of allowing users to feel how Wing Chun's techniques actually work.
Offered for sale here is our current-generation weapons-grade BJD tailored for the WSL lineage. This is our take on making something the lineage needs, rather than a pure replica of the Tommy Yuen pair - it is an effort to integrate modern design elements, tactical materials, and construction methods; for example, full-tang (American-style) ergonomic handles of Micarta type material, an AISI 304 stainless steel D-Guard, and professionally tempered modern steel blades. These are functional weapons and we make absolutely no representation that these blades are lawful in your jurisdiction.
