the best training for knife fighting/disarmament is the Fillipino martial arts
most Aikido dojos are not going to have instructors who have ever fought with knives (even just sparring with wooden or dull blades) which is important for purposes of disarming
also, the stylistic aikido attacks are not what a knife attacker would use, i.e., Kali uses a 1-10 (pattern) using the centerline as the guide which is more realistic then a "yoko-menuchi", etc.
What are you saying?
Do you think "most" FMA instructors have been in a knife fight?
Do you think the attacks in FMA are not "stylistic"?
Do you think the concept of centerline doesn't play a HUGE role in aikido?
I think it is well past time that we start separating training methodologies from the content of an art.
