Re: Tanto Practice - Is true Aikido effective for disarming?
Aikido contains all of the tools you'll ever need to take something out of some ones hand. Ikkyo nikyo, sankyo, yonkyo, gokyo, rokyo, and kotegaeshi are the very foundation of disarms. They are universal to all weapon taking systems, although they have different names in different systems.
Now using them in a high pressure situation is another story. Aikido as a system provides the information you need, however you must train in high stress, unknown, freeform situations in order to learn to use them. This is however, true of any system.
