From internet, I found that the founder of aikido fought with a naval officer in 1925. At that time, a naval officer have weapon and the founder of aikido was unarmed. The founder of aikido won this fight without hurting the officer. If someone who don't understand aikido will not understand winning without hurting. For me, although I understand but I want to know what kind of techniques did he use? The founder of aikido practiced many different kinds of martial art. So did he only use aikido techniques or did he use any other techniques? By using the simplest words, most of the martial art techniques are for the knock down purpose(at least can get a little pain in real street fight). But I think that there may have some techniques which can't hurt each other and make victory like the founder of aikido used.
Please share your ideas and let me know where can I find this history?




However, thanks for reading my question.
