Translation
Here begin the plays of reverse strikes with which countless lives have been lost. And the plays of my scholars will follow, showing the cover that I do with the right hand. This is a simple play to do, for this way I will throw him to the ground.
Explanation
The 3rd master and all his scholars defend against a reverse dagger strike. In all cases, you are moving to the outside line of your opponent. As they stab, lunge forward with your left foot and twist your hips clockwise. Cover with your right hand using a hooking block to catch the attackers wrist.
When making the cover, lead with your thumb. Your forearm comes under the dagger blade, and you catch your opponents wrist with your own wrist at the base of your thumb. As soon as you make contact, roll your wrist over into a grab.
As you make the grab, step behind with your right foot so you are to the side of your opponent. You are not aiming to stop the attack, so much as stepping around it.
While controlling the dagger with your right hand, strike with your left hand into your opponents throat using a backhand attack of your own. With your thumb down, extend the thumb and first two fingers into a pincer. These do the actual grab. Curl your bottom two fingers as if making a fist. The knuckles create a spike in the middle which push into the windpipe as you complete the grab. If you have stepped too far back, you will miss the throat, and hit the side of the neck instead. You need to be about 90 degrees from the initial line of attack. This is the situation depicted in the drawing.
Step back with your left foot. As you do so, drop your weight and turn your hips anticlockwise in a volta stabile. Throw your left hand down to your left foot in a straight line. Your opponent will fall on their back with their head by your left foot.
Transfer you opponents dagger hand from your right hand to your left. Kneel on their ribcage with your right knee to pin them down. Holding their right hand palm up, the arm will be locked straight. Place the elbow over your left thigh, creating a first class lever. Finish by pushing down, breaking the elbow.
