This is a common technique in Rope Dart. I teach things like this in a very safe manner, with a soft dog toy at the end of the rope, first! Eventually, after lots and lots and lots of practice and evaluation, I will allow students to practice on targets.
You can see the Rope Dart being used in the movie, “Shang Chi and the Legend of the Ten Rings” by the sister!
The Rope Dart is a beautiful weapon in Kung-Fu, as it represents the softness, agility, fluidity, and grace, while being an incredibly POWERFUL force for self-defense. It doesn’t look very intimidating when it’s not in motion, but then, when you see it being used, it become clear that this soft, beautiful object is quite dangerous!
