I dunno… Watch the video. How out of touch with reality does someone have to be to come up with this stuff? Would swinging a towel at a knife-yielding attacker hellbent on hurting or killing you work? I’m going to say, basically, that is a no. The towel defence method is a dummkopf idea and training. Maybe snapping the towel will work better. 🤪
Such training and easy access to towels might increase the risk of towel fights.
