Unsharpened swords (metal) in kungfu are not toys. Toys are made of plastic. If you kid the metal sword that are unsharpened, you can for sure see some tragic stuff happen. An unsharpen sword can also kill. I used to practice sword fighting with my student in 2006-2007 with these unsharpened spring steel swords. Not the wushu stuff, but dragon well stuff. He used to got his whole forearm bleeding and stuff and it was too dangerous even I am being careful, mind you that we are going at full speed too just to be fun and practical. So I was the one who say we gotta stop doing the practice with metal sword unless his skills is about my level, or else it would be too crazy.. and so we stopped the practice. he was enjoying it though, lots of bleeding and stuff. "with unsharpened swords".
Don't look at things like that, you ae underestimating unsharpened stuff. LoL!
