Hammer Fist Punch. A hammer fist impacts the target using the little finger side of a tight fist. Since this side of the fist is padded, it may be used to strike hard targets, such as the head, without injury to the hand. Another advantage is that it allows you to strike even if you are holding an object in your hand, such as a small flashlight or a yawara stick.
Bolo Punch. The bolo punch is used by boxers, mostly when they are dominating the opponent and are showing off for the crowd and or trying to humiliate the opponent. It is performed by rotating the punching arm as if winding up for the punch and the punching. The motion is similar to that used when winding up a pair of bolo before throwing them. Many times one arm winds up but the other arm throws the punch. In this case, the wind up is used to distract the opponent from the real punch. Ceferino Garcia is commonly thought to be the inventor of the bolo punch, although a 1924 article in the Tacoma News-Tribune reported a Filipino boxer named Macario Flores to be using it. As to why Garcia developed the punch, he said that as a youth he cut sugarcane in the Philippines with a bolo knife, which he would wield in a sweeping uppercut manner. Sugar Ray Leonard used the punch in his rematch with Roberto Duran, the famous "No Más Fight."
Liver Punch. The liver punch is another boxing punch. It a quick punch with a short movement, therefore, many times, spectators see it effects but miss seeing the punch itself. The punch is a left hook or uppercut that impacts under and to the front of the ninth and tenth rib and drive upward to the base of the shoulder blade toward the spine. It is usually delivered after drawing an opponent to lead with his right, which leaves the body exposed. Since the liver is the largest of the vital organs, a blow to it shocks it and causes a sickening feeling and saps the energy from the fighter.
Side Punch. A fore fist punch executed straight out to the side of the body. It is usually delivered from a side facing stance. It may be used as an initial movement before moving in with a combination attack. When used from a side facing position, you are less open to counter attack.
Double-Side Punch. A fore fist punch and reverse punch executed simultaneously toward the side of the body. Because of body position, the leading fore fist punch is executed straight out to the side of the body and the trailing reverse punch is executed across and in front of the chest. It is used to strike two opponents who are attacking simultaneously.
