I know the technique at 1:11 where he breaks the hand with the elbow. I know that technique better than I know Jow Ga Kung fu and I can tell you that you would never use that technique to counter a haymaker, or a cross. The follow up after breaking the hand is also unrealistic. That technique is a one shot deal meaning you do the technique then reset into a defensive position because another punch may be coming on it's way. Andyou are right. That knife defense is the freaking worst one I've seen. lol. oh you'll learn about mace. You have already seen one video and now you'll be tempted to watch more. Jake Mace is calling you lol. (in my creepy ghost voice) CAAAAALLLING YOOOOOOU. But seriously Jake is in good enough shape where he can be better than what he is, if he had some legitimate training. He's got a good personality and that's why people watch him. I personally don't care about his martial arts video but I could see me handing out with him and constantly reminding that he's talking crazy when it comes to martial arts self-defense lol. Jake is definitely unique. If I were to make videos I would learn from his personality and how he presents his lessons. Jake mace could probably sell fire on the sun and ice in a blizzard.
