It'w aiki-ken and aiki-jo...
Exactly. Aiki-ken and aiki-jo are just tools to help your aikido.
O-Sensei didn't have any real formal background in the weapons arts. Comparing aiki-ken and aiki-jo with koryu weapons systems like some schools of kenjutsu and jodo each with hundreds of years of study is "rediculious".
