all of the “real” Martial arts from back before guns were about using weapons. those aren’t really practiced as much anymore because they’re all useless in the face of firearms anyway. why spend years training with a knife when the same time could be spent training with a gun. if combat effectiveness is your goal then you need to learn modern combat techniques.

that said, there’s plenty to be learned from it, and it’s not like it can’t help you in a fight. but as another commenter said, the real way to win every fight is by avoiding them. so really the best thing to learn is de-escalation and recognizing danger.
