They go by many names - guandao, kwan sword, kwan’s knife... I have seen a lot of them online that break down into three parts. Does anyone sell one that is just one piece? Does anyone have experience with the ones that break down? Can they be used for aggressive form work and practice? Light to moderate contact? Not interested in a floppy blade. Heavy is fine. Just looking for a solid weapon to learn the form and develop the fitness to do it. Preferably one that doesn’t break after a year of use. Any recommendations or shared experiences are welcome and appreciated!
