It is worth clarifying a few issues here for anybody who has never trained in a martial art and who reads the above and thinks there is some validity to it. Plainly, it shows a Sensei (teacher) demonstrating technique to students in a formal Japanese dojo setting. He is working slowly and deliberately with the co-operation of a senior student to explain principles in and of a technique. It's the same method used by instructors of any martial art from BJJ to Aikido. Every so often you can see him demonstrating technique in a more compact and efficient manner, but it is impossible, in technical arts like this, to understand what he did without the slow, exaggerated demonstration and explanation preceding it. If Perry were rolling with an instructor in BJJ or Aikido who is demonstrating a technique or principal to a class and he decided suddenly to make it real by attacking with full force and speed...... someone is definitely going to get hurt. So Perry has it in for Aikido, that's a given, but from what perspective? I'm confident that Perry has never experienced Aikido in any physical manner. He doesn't seem to recognize a normal dojo teaching environment and has no understanding of dojo etiquette. In case you are wondering about "the stick" and what was going on there; weapons are used in Aikido training primarily to introduce varying combat distances, as well as variations in timing and different initiative concepts and strategies. Students study a limited set of attacks using these weapons; Bokuto (wooden sword), Yari/Jo (wooden pole) and tanto (wooden knife) to better appreciate timing and distancing. Aikido students by virtue of this limited training come to appreciate more than most, the danger a bladed weapon would present, and would be under no illusion as to their ability to offer up any practical defense without endangering their life. For those who may not know, Aikido schools do include randori (sparring) and shiai (competition bouts), similar to Judo. i.e. Shodokan Aikido, Tomiki Aikido. ( ref: www.tomikiaikido.ie) Finally Aikido has a lot of jujutsu techniques in it's arsenal ; including restraints, pins, locks, breaks and throws: finger locks, wrist locks, arm locks, shoulder locks, elbow leg locks, foot locks, hip throws, shoulder throws, arm throws, sacrifice throws and some atemi (strikes). ..it's up to the student to take the time to practice and hone their skills so that they become effective.

@@vosoft I was into boxing for a few years and had friends who took aikido. They quit after realizing that they would not have any practical ability to defend themselves until they had a high black belt which could take decades. The thing that really bothers me is any martial art that teaches knife defense. I know something about knife fighting and I'm telling you that aikido is not teaching a knife defense that will do anything but give false feeling of thinking they can defend. Kids will leave dojo's thinking they can fight having never had a single sparring match in years. Maybe there are aikido dojo's that teach practical self defense, but I don't see it and most martial arts practitioners agree with me. Aikido is 99% wrist lock dependent. Think about that. And BJJ Teaches practical street fighting techniques, not sparring with opponents who cooperate 100%. Its one thing to nit try to hurt your opponent by holding back and another to cooperate 100%. Come on, I am not being a jerk. Think about what I am saying before you go off of a martial arts etiquette rant. Let's be honest and drop the etiquette. Do you honestly think most aikido dojo's prepare students to be able to defend themselves against a real opponent. How can they call them opponents. Opponents are opposing you in sone way, not cooperating, This guy is showing how to deal with someone who helps you throw them. Come on. That's what most aikido dojo's do. They teach how to throw cooperating partnêrs. I say partners because there are no opponents in aikido dojo's.
