Although the UFC has done a lot to kill Bullshido, there's still a big elephant in the room that refuses to die: unarmed techniques against knife attackers. It really blows my mind how people can still believe in this crap, especially when there's almost no example of them being executed in real life. The closest I could find was this badass Chinese female cop sneaking behind a guy, but even then if she failed they could have blasted him before he stabbed her to death. Nevertheless, self-Defense systems like Krav Maga still teach this crap like it was proven in real life. What they should be teaching people is to carry a concealed knife and use it against a knife wielding attacker. So learning something like Argentina's Esgrima Criolla would be more helpful in the street than bullshido fantasy techniques.
