The muscle groups and angle range of movement of the fingers are very small, so the fingers are the most vulnerable joints in the human body.
In general, the normal range of motion of the fingers is as follows: the opening and closing degree of the thumb is about 50-60 degrees (Figure A-1); The opening and closing degree between the remaining four fingers is generally not more than 35 degrees (Figure A-2); The four-finger dorsal hand is upturned, generally between 10 degrees and 30 degrees (Figure A-3); Flexed into a fist can reach 80 degrees to 90 degrees (Figure A-4).
Therefore, we implement the finger grappling technique, which is to follow the direction of the enemy’s finger range of motion maximum, exert force to force the enemy’s knuckles beyond the limit of the normal range of motion mentioned above, and be oppressed and hit by the superphysiological limit, resulting in severe pain and having to give in and beg for mercy.
Sorted out 12 sets of knuckle grappling techniques and shared them with you.
First, pout your thumb
The enemy points and provokes us with his right hand in front of us; Seeing the opportunity, we grasp the enemy’s right thumb with our right hand, clench it with four fingers, clasp the enemy’s metacarpophalangeal knuckles with our little finger, clasp the wrist downwards and pull back the enemy’s thumb that is pressed down, causing severe pain in the thumb and begging for mercy (Figures 1-1, Figs. 1-2).
2. Pouting index finger (1)
The enemy’s palms are facing down, ready to poke us in the throat; Our side quickly grabbed the enemy’s index finger, and the side of our little finger pressed the metacarpophalangeal joint of the enemy’s index finger, first moved forward, then pressed down and dragged back, so that the enemy’s index finger turned up beyond its limit and was painful, so as to bow down and catch (Figures 2-1, Fig. 2-2).
3. Pouting index finger (2)
The enemy’s palm strikes us, and we use our hand to grasp the enemy’s index finger extending from the palm, turn the wrist inward, and force the enemy’s palm upward; Immediately after our side, we press the metacarpophalangeal joint of the enemy’s index finger with the middle section of the index finger, press down and push forward with the thumb, then shake the wrist upward, stretch the arm up, and pout the enemy’s index finger downwards to force the enemy to submit (Fig. 3-1, Fig. 3-2).
4. Thumb pressure
Our side pretends to shake hands with the enemy, when our hand just touches the enemy’s hand, we slightly lift the elbow wrist outward, the thumb presses the metacarpophalangeal joint on the side of the enemy’s thumb, the index finger is extended forward, the thumb is pressed down hard, the upper end of the enemy’s thumb is jammed with the index finger and reversed, and then the entire wrist is rolled to the side forward and down, forcing the enemy to fall to the ground and catch (Figure 4-1, Figure 4-2).
5. Double buckle finger
When the enemy reaches out to us, we will aim at the enemy’s mouth and snap our index finger forward. Immediately, our wrist was lifted upwards, twisted the enemy’s thumb back with thumb pressure, and took advantage of the enemy’s pain to separate the four fingers, and used the tiger mouth of the other hand to aim at the enemy’s little finger, move the front thumb back, and kickback the index finger of the back hand, and at the same time drag the wrist down to submit the enemy to the enemy (Fig. 5-1, Fig. 5-2).
6. Flip your fingers
When the enemy reaches out to us, we first hold the enemy’s hand and twist it back, clasp the enemy’s little finger with four fingers and little finger at the same time, immediately exert force, flip the enemy’s wrist clockwise, and at the same time tightly clasp the metacarpophalangeal knuckle of the enemy’s little finger with the middle knuckle of the four fingers, sit on the wrist and pout the finger, and submit the enemy (Fig. 6-1, Fig. 6-2).
7. Oblique fingering
The enemy punches us in the chest with a straight right fist; We block the defense with our left arm and grab his right wrist, while our right thumb and index finger clasp the little finger of the enemy’s right hand, and our left thumb and index finger press the enemy’s right thumb. Immediately, our right hand clasped the enemy’s right little finger down, and the left hand pushed his thumb diagonally up, causing severe pain and giving in (Fig. 7-1, Fig. 7-2, Fig. 7-3).
8. Clamp the elbow and pull the finger
From behind the enemy’s flank, we grasp the ring finger and little finger of the enemy’s left hand with our right hand, and press the thumb against its metacarpophalangeal joint. We put the enemy’s big arm in the crook of our elbow, push the enemy’s elbow joint with the left hand, push the enemy’s metacarpophalangeal joint with the thumb of the right hand, and pull the enemy’s finger back to cause severe pain and yield (Fig. 8-1, Fig. 8-2).
IX. Sub-fingers
We can force the enemy to submit and capture by grabbing the enemy’s fingers with both hands and tearing them to the sides (Figs. 9-1, Fig. 9-2). If the enemy stops us from behind, we can also tear the enemy’s fingers to free us (Figure 9-3).
10. Pressure arm sub-finger
We grasp the enemy’s ring finger and little finger from the enemy’s side, roll our fingers and raise our arms to press the enemy’s elbow joint, support the enemy’s wrist with the left hand, and continue to flex the wrist with the right hand, while using the big arm to force down the enemy’s elbow joint to make the enemy fall to the ground (Figure 10-1, Figure 10-2-Figure 10-3).
11. Positive pressure finger (1)
If our wrist is caught by the enemy, we should first penetrate the wrist from the bottom out and then upwards, so that the enemy’s mouth turns downward. Immediately, we clasped the enemy’s wrist with the four fingers of the other hand, and the thumb firmly held the enemy’s thumb, causing the enemy’s thumb to abduct beyond its activity limit and cause pain, so as to give in and capture (Figures 11-1, Fig. 11-2).
12. Positive pressure finger (2)
The enemy’s left hand grasps our left wrist; With our right hand, we grab the enemy’s left big arm, lean down, and press the enemy’s thumb with the left wrist to submit the enemy (Fig. 12-1, Fig. 12-2).
