Developed in response to requests from Wushu practitioners for swords with ultra-flexible blades, the Practical Wushu (SH2062) sword from Hanwei has a spring steel blade that tapers to almost paper-thin at the tip. The light weight (barely one pound) of the sword makes it extremely fast in skilled hands.
