Translation
From the play before me, and as the scholar said, I put my sword at your neck, and I can easily cut your throat because I feel you do not have a protective collar.
Explanation
Following on from a pommel strike as either the 2nd scholar or the 3rd scholar of narrow play, you now enter this devastating finishing move.
You begin this play on the outside line of your opponent, with their sword safely out of the way to your right. Your own right hand is perfectly placed in front of their face. Keep it as a stable point for a moment and move everything around that.
Turn your wrist, spinning your sword in a horizontal arc around your opponents neck. As you do so, step past your opponent with your right foot. Step with your front foot turned toward your opponent as you do so. Quickly follow with your left foot in a light, fast movement.
Raise your left hand up to your left shoulder. As your left foot lands, your sword should slap with the flat of the blade into your hand. You will be facing the complete opposite direction from where you started. This is the moment depicted in the drawing.
Step back with your right foot, and as you do so, pull your right hand back to your right shoulder. This will pull your opponent backwards off balance and stretch their neck out. Your sword blade should go under their chin, with the flat of the blade just balancing on the corner of their jaw. Their head should be cradled under your chin.
Pivot 180 degrees on the balls of your feet, to end facing the same direction you were facing originally. Your right foot should be forward. As you pivot, roll your wrists down and pull both hands back as tight to your shoulders as you can.
The edge of the blade will roll onto the left carotid artery. Although your arms are locking the head in place, it is the turn of the hips which does all the damage. You are effectively throwing your opponent in a backward twist by the head using a sharp object to grab them. This will sever all the way to the neck bone with dramatic results.
