Even though aikido does not always train to strike the openings or vital points when you seriously look at the technique you can see the opportunity for multiple strikes throughout a technique. This is sort of like some styles of karate like Ryukyu Kempo/Tuite where they show all the strikes to vital points inherent in the forms or katas. As an example, I can think of two atemi strikes that can be performed without disrupting the flow off a tenkan blend against a munetsuki strike. One may be obvious the other more subtle. They can be done with speed and power causing either pain compliance or possibly numbness in the arm. It makes them more compliant for kotegaeshi
