Re: Tanto Practice - Is true Aikido effective for disarming?
I just attended a Bob Koga seminar last weekend. For those who don't know of Koga Sensei, he is the architect of "Practical Aikido" and a long-time police defensive tactics instructor. Originally a martial artist, Koga Sensei became "The Man" for law enforcement with LAPD. All this is to suggest that he knows what he's talking about.
He made the statement that martial artists have an advantage over the average person when confronted with a knife, but they could also count on one of two consequences when defending unarmed: they will die or be seriously injured. He said the only way he would attempt to take a knife away while unarmed is if he were locked in an empty room, stark naked, with his attacker. Otherwise he would attempt to flee or find a weapon of some sort.
He said the major advantage to being a martial artist is the development of awareness over time and the skill to see and feel when trouble is brewing. Since most of his teaching is to cops, he doesn't use terms like "ma ai" or "zanshin", but rather distance and awareness.
Can you do it? Sure. Will you be injured? Quite probably. Should you do it? Only if you have no other choice.
