Yeah, that's what I'm most interested in personally. Does anybody have a specific method or course to recommend with an emphasis on disabling moves (as well as general utility, ofcourse)?
Silat and the FMA's are loaded with them. With those systems you can't go wrong. You learn how to use the weapons, disarm, disable and even translate it all to empty hand forms.
Considering how knife / shiv attacks are on the rise, I think it would be very beneficial to learn this. How serious are you about self defense? Knife / blade violence is on the rise and will always be the poor mans weapon as guns are not as easy to come by for the vagrant type. I am a firm believer in covering my ***, so I have trained to defend against blades, sticks and guns and how to use them.
