I don't mind being wrong.

Weapons. Ueshiba doing weapons does not look like any koryu I know of or have seen. In fact, people keep trying to find the koryu he took things from. How about we take Ueshiba at his word ... with aiki, we would do it this way. Which leads us straight back to Daito ryu aiki, now in weapons. Courtesy of Sokaku Takeda.

The Founder showed a great interest in the sword throughout his martial arts career. He even received a Yagyu Shinkage-ryu sword certification from Sokaku Takeda in 1922 although the exact content of his sword training under Sokaku is not known. Later in 1937, he officially joined the Kashima Shinto-ryu classical school which had an influence on his experimentation with the sword especially during the Iwama years from 1942 to about 1960.

O-Sensei made no attempt to codify or develop sword kata to be used formally in aikido training. The sword was for the Founder an extension of divine power to be used only for life-giving purposes. His sword work—and the same can be said of his jo—was merely a different tool for the expression of aiki movement based on the same universal principles as taijutsu techniques.

The founder of AIKIDO, Morihei Ueshiba O-sensei, spent many years adapting techniques from Daito-Ryu Jujitsu and other martial arts to embody the principle of AWASE.
