Hand Attacking Tools

 
The hand creates so many types of tools that special care should be paid to the selection of the appropriate tool for the appropriate target.

Forefist
Taekwon-do.nl | Hand attacking parts The forefist is generally used for attacking the philtrum, ribs, solar plexus, chest, abdomen, jaw, etc. The main knuckles of the forefinger and middle finger arc the punching parts. The top and the front of the fist should form a right angle so the punching parts can be closely contacted with the target. The wrist should not be bent when the fist is clenched. The forefist is occasionally used for a pressing block

How to make a clenched fist (Jwinun Bop)
If the fist is not made firmly and correctly and if there is even the minutest of air space, the fist will be as weak as untempered steel and as soft as cotton. The fist must be tightly clenched at the moment of impact.
  • Open the hand naturally.
  • Roll the fingers tightly.
  • Press the fingers into the palm, starting with the little finger at the same time bending the thumb toward the inside.
  • Place the thumb on the forefinger and the middle finger pressing the forefinger properly.
The reasons for not bending the wrist are:
  • To prevent the wrist from being blocked or grabbed by the opponent.
  • To align the punching parts of the fist exactly on the target.
  • To concentrate maximum force on the punching parts.
For maximum power the front two knuckles must contact flush against the point of impact. Mathematically, power generated from the hip must flow in a smooth unbroken line through the forearm and out through the apex of the front two knuckles.

Knife hand
Taekwon-do.nl | Hand attacking parts
This is very powerful attacking tool, especially against a side target, and is used for attacking the skull, neck artery, bridge of the nose, temple, philtrum, clavicle, shoulder and floating ribs. The knife-hand is also frequently used for b1ocking.

Press four fingers together bending the middle finger and ring finger slightly inward leaving some space between the forefinger and thumb, so that most of the strength is concentrated on the striking part, the surface from the wrist to the main knuckle of the little finger.

An incorrect way of forming a knife hand is by pressing the thumb against the forefinger. This will weaken both the knife-hand and fingertips. In both cases, the joint of the little finger should not be used by beginners due to its weakness.
