  • Martial artists start by curling their fingers down into a fist.
  • They then lift their middle finger until the last knuckle of the middle finger is even with the second knuckle of the ring finger and pointer finger.
  • They can also reinforce their extended knuckle with the thumb. Place the side of the thumb on the first knuckle of the middle finger.
  • Martial artists can strike forward with this fist against a target. Less effective against hard/bony targets.
  • They can also punch down on the back of the hand that is holding them in order to force an attacker to release them.
