Gokyo is the fifth technique in the series of techniques the Sensei established. And it is primarily used in removing a knife, or a Tonto, from your partner's hand. But we'll demonstrate it real briefly.
Let's start with the Shomenuchi. So normally when we start Shomenuchi, in this whole series we begin from Ikkyo. Things change a little bit at Gokyo. Normally we would have our hand on top, and rotate it over, so that I'm grabbing his wrist from the top here, if we were to execute Ikkyo. For Gokyo, both hands come up underneath. As I move away I'm going to grab his wrist from underneath, and lock the elbow. And move away from my partner, shoulder goes down. Knee closest to my partner is down. And I'm going to use the elbow to lift. Hand slides underneath the elbow, and you want to put pressure down on the elbow. With a pin. So Gokyo. Shomenuchi. Up. Turn. You've got the hand from underneath and the elbow is locked. Straight down on top of the shoulder, Again, knee that is closest to your partner is up. Lift the elbow. I'm going to use my hand to push my partner's hand underneath the elbow, and apply pressure. You'll notice that it's almost impossible for my partner to make a fist in this position. Which is exactly why it works very well with the Tonto.
So from that same attack overhand, the Shomenuchi, one of the reasons I don't want to put my hand here, is if the blade were to cut down and make contact with my wrist. That's why I'm going to come from underneath, lock the elbow and take it away from my partner's body, and drop. When it's out, slide the Tonto underneath, and the hand will pop open. It's very difficult to keep a fist in this position.
You can also see this from Yokomenuchi. Open, reach across and take the wrist, turn the hips, create the pin, and take the knife. Alright?
Gokyo. Number five.
