as the title, i want to know the safety movements in using the forearms to attack, especially the one with the forearms weapon like in hung gar, i am not knowledgeable in unarmed fighting but i believe it risky in damaging the wrist or the forearms if not done right, or maybe correct me if i am mistaken, and if theres any difference in using pure metal bracelet (not the ring one, i remember the original or historical one is made from bronze with spike) rather than leather?
here some forearms weapon example i can found.
