So I've been wondering: What are the origis of iriminague?
Fabrício Lemos, Brazil
It is my understanding that irimi-nage was refined from the battlefield technique (weren't they all!) on entering thru an enemy's attack and attempting to break his neck by twisting the helmet violently (which was securely strapped to the head). Obviously the developement of martial "practice" dictated a gentler method.
Any other theories?
