Answer: Not really, but you can
Step-by-step explanation:
The Human Body is extremely weak. Some people don't know that even a soft blow to the front of the necks’ cartilage is very dangerous or fatal. Chopsticks are traditionally utilized as an improvised weapon. Martial artists have trained with them and carried them as weapons for centuries, but as far as I know, no specific martial art teaches chopstick techniques. There is a martial art similar to that idea. Escrima (arnis/ kali) uses motions that can be applied to pretty much any tool or weapon. Things like batons, knives, pens, pencils, etc. Even open hand. Hope it helps you
