Re: Tanto Practice - Is true Aikido effective for disarming?
One of the things we've learned in the police world is the view of a knife versus a gun. A firearm is intimidating certainly, but most people have never experienced what a firearm can do to another human, except on TV and then the actor shows up on the following sitcom. We've all been cut by knives at one time or another and generally know how dangerous they are. As a result people are usually far more frightened of a knife than they are of a gun.
On the other hand a real knife man will cut you to ribbons before you even realize a knife is part of the equation. In my own limited view, if your assailant lets you see his blade, he probably isn't a skilled knife fighter. Does that mean that you can defend yourself more effectively? Perhaps. Maybe he will be really clumbsy in his attack and maybe he will panic and go crazy with his blade.
You're certainly better off than someone who does no martial art at all, but unless you train constantly and rigorously for knife defense, you are going to be injured, and perhaps injured badly.
