Bravo, I'm so proud!!!*Holds my hands in front of me, focusing on my chakra flow, focusing towards the entirety of my hands. I pause for a moment, familiarizing myself with constantly feeding the chakra to the two locations, focusing on sustaining an unwavering flow. I then begin to focus more on the shape of the emanating chakra, extending my index and middle fingers fully, while bending my ring and little fingers on each hand, bringing my thumbs into the creases of the two extended fingers. I focus the flow of chakra along the length of my two extended fingers, making the chakra flow out of the end of those fingertips. I then attempt to shape this into a small point in between my two fingers, making it as fine as possible, all the while focusing on maintaining the flow of chakra to that area. I then stop doing this. I then begin imagining that an enemy is close to me, starting to attempt to hit me with a right hook. As the enemy's fist moves to the left side of my head, I quickly bend my knees, lowering myself below the point that his fist is nearing. I then focus a steady flow of chakra into my fingers as I make the finger-striking hand position with my right hand, focusing on making a very fine, sharp point. I then slide my left foot to the enemy's right side, striking at the left side of the wrist of the enemy's right arm (which he is attacking with.), and then quickly sliding my fingers across, causing the slicing of the Ulnar and Radial arteries, which would cause significant blood loss in a relatively short time. (With every heart beat, blood is released from the sliced vessel. This wound, if left untreated will cause a series of circulatory problems that will eventually result in circulatory collapse and then cardiac arrest.) The Ulnar and Radial nerves are also cut, causing the fingers, hand, and significant part of the arm to become numb and immovable(due to the muscles in the forearm and hand that are now unresponsive.), which should probably cause shock, heightening the heart rate, increasing the rate of internal bleeding. The enemy, in the heat of the moment of his full force punch, probably would just be noticing the effects of that first hit as I, retaining the sharp chakra point on both hands, quickly perform three quick strikes, the first two of which target the tenketsu just above the elbow, below the circular formation with the left hand and the tenketsu on the circular formation on the inner side of the arm with the right hand, precisely pointing into the tenketsu, causing it to close, blocking all chakra from moving through those individual vessels past those points. I then proceed with the third strike on the tenketsu on the under side of the arm with the left hand, near the shoulder, above the circular formation, in the middle of two other vessels, effectively blocking chakra from the area just above the elbow and below. As I continue my slide, my body just now moving past his side, I use my right hand to strike the front part of the armpit where the arm and torso meet, severing the right Axillary artery which, by proxy, severs the right subclavian artery that transports blood to the right arm, causing more internal bleeding. This also causes the severing of the Brachial Plexus, leaving the enemy with the ability to do no more than move the top of the right shoulder. As I retract my hand from the last strike, I halt my sliding with my left foot and slide my right foot immediately forward, turning my torso and head to the left so as to face the enemy, putting me behind him, slightly to his right side, behind his shoulder as he finishes his strike, hitting the air in front of him. I then quickly shift my weight forward on to my left leg, which stayed in place as my right one became the one behind me, striking towards the back of his head with my right hand, focusing chakra into it as it nears its target. Upon contact with the back of the enemy's head, I release the chakra into the enemy, damaging the cerebellum, causing the enemy to lose some control over his motor skills, leaving him incapable of being precise in his movements. Aside from the damage taken from the other techniques, he now finds basic motor skills to be quite a challenge and fighting me is now completely out of the question.*
Pointers: The chakra knife is really tiny, so with every hit, only one artery or nerve will be cut, and the more exterior the nerve is, the better. The cuts are only small holes, which means that if the fiber you try to cut is too thick or big, it won't have any effect. With that being said, you can either damage big nerves or arteries, or severe small nerves and veins. Either way, you're limited to very small tissues and wounds, and have to make the most out of that strike. So, for instances, if you aim the knife to the heart, even if you to try to cut the arteries, the damage will be minimal.
Either way, damage to some of the bigger nerves will still cause a lot of pain and impairment of movement, despite not being permanent. So, let's recap, aiming for major arteries and veins, especially near the heart, will not have any effect. Aiming for major nerves will have temporary effects, which is still great. Aiming for tiny arteries/veins will provoke localized internal bleedings, which may or may not be good for you, while severing tiny nerves will result on the permanent loss of utility.
Also when you have the back of the opponent, a nice move is slamming your hand on the Occipital Ridge, which will cause immediate loss of consciousness.
