Butterfly Swords Form

Functional Butterfly swords for wing chun / hung gar?
Im looking for a pair of butterfly swords that would be functional for practice and performance, but at the same time I want them to be well made, decent looking, and practical. The majority of the butterfly swords on the “market” are pretty crappy but i found a set of paul chen swords with Rattan wrapping. Im not sure if the rattan on the handles would impede any form of practice or not but i really like the blades as they match the demensions of my arm. Thoughts? And if these are terrible, any suggestions for a quality pair of swords that aren’t just for show? (and I think these are.)
