I've never seen Aiki in Aikido weapon work, so I don't know what to call it other than aikido weapons.
Since it seems to match aikido movement of ___________________flavor of any group, there's really nothing to discuss ...its just a bunch of people having fun....until the mid dan and kyu ranked people start to once again " imagine" they're doing real weapons, or that what they're doing is aiki.
Dear Dan ,
If it is not too much trouble may I ask you who have you seen doing Aiki ken /Aiki Jo/Tanto work?As it happens I do not think that serious aikidoka perceive Aikido [body art /weapons/ Batto ho/ Za Zen as fun. Neither do they imagine they are twirling 'real ' weapons as such.In Batto Ho as it happens the use of a live blade is permitted. Naturally if one uses a katana one cannot adopt a flippant approach to using a live blade.Not only would you injure yourself , you may well injure someone else if you did not have a serious attitude /safety in mind.Cheers, Joe.
