I do the grip of my master that was seen previously, and my right hand leaves it grip, and if I hold you under the right elbow I can dislocate the arm. And also with such a grip I can put you on the bind that is the strong key, that the third remedy master of dagger shows in the sixth play.
Against a sottano attack, use a sword grip to grab your opponents wrist using the cover of the 9th master. Step back with the left foot, overextending your opponent. As you do so, slide your right hand up to grab the elbow joint as shown. What happens next depends on the balance point of your opponent.
If they are pulled completely forward, then take a second step back with your right foot. As you do so, brush your left hand across to your left hip and lock it there, directing your opponents blade past the front of your waist. Make a sudden volta stabile and pull your right hand up to your left shoulder in a fast, sharp movement. Your opponent will go flying past you at tremendous speed with a broken elbow. There is too much leverage for them to prevent this.
Alternatively, if your opponent is not pulled completely off balance at the picture point and withdraws their arm, you can push your right hand to the left slightly. This will move the dagger a little to the left, and also bend the opponents arm. As they withdraw their arm, step forward again with the left foot into the gap you have just created.
As you step through, keep your right hand as a fixed point in space. With your left hand, scoop your opponents right wrist down and then up. Set your left foot against your opponents right foot, push your hips under theirs to steal their centre, and then arc your right foot behind you to turn 180 degrees. Your left hand pushes down on the back of your opponents shoulder. Their right hand will be bent behind their back and pushed high up on their spine. This bind appears several times throughout armizare, first being described in the 5th scholar of the 3rd master of dagger.
